The article proposes a new approach to temperature control in a building based on the Visible Light Communications technology. This approach is based on using LED lamps as temperature data transmitters as well as for lighting. Light modulation based on the UART standard was used for data transfer. A photodiode with the capability to distinguish relatively weak signals was used for receiving data. All data processing was performed by microcontrollers. UART-based modulation was also performed on a microcontrolle. The article describes in detail schematic circuits of transmitting and receiving devices. Based on developeed schematic circuits, a new experimental setup consisting of two units was created. The transmission unit includes a temperature sensor, a microcontroller, a driver and an LED. The receiving unit includes a photodiode, an amplifier and a microcontroller. An ATmega328P chip was used for both microcontrollers. Experimental setup consists of experimental models of both units. For signal transmission control, measurements of the pulse level and shape were conducted in the receiving device with an oscillograph. The signal level was anaylsed after all electronic components but before entering the microcontroller. Experimental results have shown that data transmission with the use of white LEDs was relatively stable. This allows the possibility of organising wireless control of temperature conditions on premises without Wi-Fi. Perspective uses of temperature control with white LEDs approach include the creation of “Smart house» control system without using wirelines and with cheap microcontrollers, which signficiantly decreases costs of the system.

Ketika suhu terlalu tinggi, maka kipas akan menyala dan lampu akan mati, sedangkan jika suhu lebih rendah dari set point maka lampu menyala kembali dan kipas akan mati. An automatic egg hatching room has been successfully designed by using the DHT-11 sensor based on the ATMega328p microcontroller. The system is designed so that the temperature and humidity of the plant room can be adjusted automatically. Automation of controlling this system is quite complex and requires various integrated components with the ability to read input, data processing and controlling output simultaneously and programmed.

In this paper, a digital trainer was designed and implemented. The purpose of a digital trainer is to teach students logic design skills in the digital electronics laboratory and provide them with hands-on experience in working with and modifying simple network digital circuits. The conventional digital electronics trainer is both costly to obtain and available in limited quantities in most electronics and computer engineering labs, which also leads to high maintenance expenses. Therefore, this project concentrates on developing a digital trainer that is both cost-effective and efficient. The digital trainer was designed with an ATmega328P Microcontroller, which helps monitor and control the functioning of the system features in accordance with a set of written program codes and whose operating voltage ranges from 3.3 to 5.5 volts. It was designed to involve a function generator and LEDs. The function generator requires 12V to generate different waveform outputs, while each LED requires a minimum voltage of 1.7V to glow. The user provides input through the logic switches to the logic gates, which are then read by the Microcontroller. When the input from the logic gate is detected, the ATmega328P Microcontroller sends output through to the LCD, displaying the features in operation with the LEDs and showing the result of the tested circuit.

Full textAbstract:
<p>Intelligent electronic systems are increasingly prevalent in modern society. The development of smart bedrooms for young children, especially those with developmental disabilities, it is based on the responses of passive infrared (PIR) and light dependent resistor (LDR) sensors. The PIR sensor detects children’s movement during the night, triggering the microcontroller to send a bit of 1 to the microcontroller pin connected to an electromagnetic relay, which then switches on a 220 VAC light to illuminate the bedroom. This only occurs if the LDR sensor has high resistance, indicating that the environment is completely dark. The functionality of this intelligent system mainly depends on the program code (sketch) uploaded to the Arduino UNO microcontroller module. The microcontroller is programmed to perform specific functions based on the sensors data. It is based on the responses of PIR and LDR sensors. The PIR sensor detects children’s movement during the night, triggering the microcontroller to send a bit of 1 to the microcontroller pin connected to an electromagnetic relay, which then switches on a 220 VAC light to illuminate the bedroom.

Full textAbstract:
Applications of power supply systems to supply sensors that require high voltage values are widely available in the market in the form of modules. However, in general, setting the voltage value is open by providing a voltage value from the potentiometer or trimmer component which is rotated manually. This becomes less flexible because the operator must always be nearby. The solution option is to implement automatic regulation via a potentiometer attached to an interface component connected to the microcontroller via a serial communication line called I2C. Furthermore, the microcontroller is programmed to receive regulatory commands and monitor the desired voltage value from a computer or mobile phone. This study uses the ATmega328P microcontroller, the MCP4725 DAC module and the CA12P-5TR series HV module from EMCO products. The results of this study are the design, implementation and prototype scheme.

Technology at this time completely occupies the lifestyle of human beings. Even though there is such an advancement in technology, there are still people whose lifestyles are very far from this advancement. The goals of this research are to enable an electric fan to change its speed level automatically in response to temperature changes and to design an automatic fan system that can vary its speed level in response to changes in the environment's temperature. The designed technology creates an atmosphere in which the fan speed is controlled by the system rather than the user. This fan automatically controls itself by sensing the temperature of the room and regulating itself to suit the temperature of the room.

An appearance of radiometers and dosimeters on free sale made it possible to provide better radiation safety for citizens. The effects of radiation may not appear all at once. They can manifest themselves in decades to come in future generations, in the form of cancer, genetic mutations, etc. For this reason, we have developed in this paper a microcontroller-based radiation monitoring system. The system determines an accumulated radiation dose for a certain period, as well as gives alarm signals when the rate of the equivalent dose exceeds. The high reliability of this system is ensured by a rapid response to emergency situations: excess of the allowable power of the equivalent radiation dose and the accumulator charge control. Further, we have composed a microcontroller electronic circuit for the monitoring radiation system. Additionally, an operation algorithm, as well as software for the ATmega328P microcontroller of the Arduino Uno board, have been developed.

In the manufacture of aircraft there are systems - systems that are very complex and must be integrated with each other, these systems are integrated with each other with wireharness transmission media. Wireharness is a collection of cables that are tied to form a bundle into a single unit. The continuity testing tool available today uses a multimeter, the disadvantage of using a multimeter is that it takes a long time to carry out because it must be tested one by one point to be tested while there are quite a lot of points to be tested, both operators often have difficulty when looking for cable addresses on the wirelist, the three tools used are not flexible. The purpose of this research is to design and make an aircraft wireharness continuity test tool that can test quickly because it can test many points at the same time, makes it easier for operators when looking for cable addresses on the wirelist, and is flexible when testing because it can measure two points that are quite far apart. far compared to a multimeter probe. This tool has two parts master and slave and each part uses an Atmega328p microcontroller-based controller as a data processor. Then also used 2 CD74HC4067 ICs, namely a 4 to 16 line multiplexer/demultiplexer whose binary output is controlled by a microcontroller. As well as for unidirectional communication between master and slave using NRF24l01+ (wireless). To operate the tool and display the results of the wireharness test, an application program was created using Visual Studio 2010 with the Visual Basic programming language. The system created will be realized into hardware capable of conducting a continuity test of 32 connection pin points in a multipoint to multipoint manner. After all systems are realized, then further testing is carried out on the tool, where this test is carried out to find out whether this tool can operate in accordance with what was planned. In continuity testing with this tool, it is able to produce good tests because it is able to carry out multipoint continuity tests and the communication distance between master and slave is 20 meters, and the testing time using this tool is 46.2% faster than using a multimeter. By using this continuity tester to speed up the work, the result is safer because the cable connections are not confused, can test the connection is disconnected or connected.

Our new system improves emergency response and medical care coordination by combining the features of the ATmega328P and NodeMCU. A core part of our system uses these microcontroller units to keep track of where ambulances are using GPS. This information is available in real time through a Blynk webpage. This feature makes sure that ambulances are sent out quickly during emergencies by letting dispatchers keep an eye on and redirect vehicles as needed. Our system does more than just manage traffic; it also adds biomedical monitoring to the ambulance infrastructure. The ATmega328P powers biomedical sensors that constantly collect patient data while they are being transported. These sensors include heart rate and temperature monitors. This information is sent to an IoT webpage in real time, so doctors can keep an eye on it from anywhere. Healthcare providers can make smart choices and act quickly, even before the ambulance gets to the hospital, because patient data flows smoothly. This ability to monitor in real time improves patient outcomes by allowing for the early detection of important changes in health status. In short, our system uses ATmega328P and NodeMCU technology to make a complete solution for coordinating emergency response and medical care. We want to make emergency medical services more efficient and effective by combining GPS tracking, traffic management, and biomedical monitoring. This will lead to better outcomes for patients in critical situations.

Toddler development stage is an important thing to always follow-up. A child is not the same as a miniature adult. Small children are still experiencing a process of growth and development. These two processes are important for the child's future in terms of physical and brain development. Delays or abnormalities at the stage of toddler development can have a negative impact on the toddler. This is the reason why knowing the stage of toddler development becomes a very important thing. Monitoring toddler development can be more practical by utilizing a combination of technology between microcontroller control and database usage as a result of monitoring. Monitoring conducted on toddlers can include monitoring the development of body weight, monitoring body temperature, and monitoring the toddler's heart rate. This microcontroller can process data generated by load cell, temperature sensor and heartbeat sensors to be processed and displayed in real time using the web with a MySQL database. Users who have logged in can access data on the development of body weight, body temperature, and heart rate of toddlers with good and organized records wherever and whenever. So that toddler development can be known easily. Designing a monitoring system for toddler development using a microcontroller that is integrated with the MySQL database at the Posyandu Pian Raya Kabupatem Musi Rawas can be a good solution so that toddler development data can be controlled and accessed anytime.

In this study, a low-cost water level measurement device based on an ultrasonic sensor was developed. The ultrasonic sensor used is Maxsonar MB7389, and the data acquisition system uses the ATMega328P Microcontroller. Meanwhile, water level measurement data is displayed in real-time on a computer and also stored in a microSD card where data can be retrieved at any time for analysis. The choice of the Maxsonar MB7389 sensor for sensing water levels is based on its superiority in water resistance so that it can be applied in the field, and the measurement resolution is up to millimeters. Meanwhile, the ATMega328P microcontroller contained in the Arduino Uno board has advantages in terms of its relatively low-cost price, ease to program using the open-source Arduino IDE software, supported by many libraries, and modules. Based on the results of laboratory-scale testing, the measurement device developed can measure the water level quite accurately. That can be seen from the average water level measurement error for sensors without a casing of 0.31 cm and sensors with a PVC pipe sheath of 0.25 cm. Then, the value of the Pearson correlation coefficient (R2) is 0.99 for sensors without pipe casings, and 1 for sensors with PVC pipe casings. Then, based on the ripple comparison of the results of the water level measurement, it can be suggested for the measurement of the highly fluctuating water level (such as sea and river) should use a pipe casing. Meanwhile, for measuring the water level in the tank that is not too volatile, you can use a sensor without a pipe casing.

Целью данной работы является изучение возможности практической реализации нового информационного подхода к автоматическому регулированию на базе микроконтроллерной техники. В современных автоматических системах алгоритмы управления основаны на методах нечеткой логики и использовании искусственных нейронных сетей. Применение разрабатываемого преобразователя управляющих воздействий не требует сложной настройки параметров регулятора с помощью экспертных оценок или проведения процесса «обучения». Анализ научной литературы и современных публикаций выявил отсутствие стандартных библиотек для программирования таких преобразователей на микроконтроллерах или программируемых логических контроллерах. В основной части статьи проведено сравнение аппаратной реализации и принципа работы звена чистого запаздывания и преобразователя управляющих воздействий, разработан алгоритм их выполнения на микроконтроллере ATmega328P. Предлагаемый авторами вариант программной реализации преобразователя управляющих воздействий нулевой вибрации позволяет получить погрешность временной задержки не более 2 %. По результатам экспериментальной оценки разработаны рекомендации по коррекции значений времени запаздывания с учетом требований программного обеспечения микроконтроллера для реализации полученного регулятора. Применение регулятора, работающего на основании новых информационных подходов, позволяет уменьшить время переходного процесса в системах второго порядка с единичной обратной связью и снизить значение перерегулирования до нуля.

AbstractHeavy equipment industry ia an employment sector with potentially high rate of accidents, which might occur due to the operator's own fault, where he or she does not have competence in operating such an equipment. This operator's fault accident ranks number two after that of the mechanic's accident rate, which is the focus of this research. In line with the latest digital electronical development, companies have been able to solve problems confronted with operators, one of which is through the application of biometric authorization device, which has been expected to be able to reduce the rate in the industrial accidents in heavy equipment rental. This device works by requiring authorization of the operator without inserting the manually inserted Ignition key to the machine, but the operator' fingerprint that has been authorized into the system to operate such a machine. This, in turn, Will be able to reduce risks of getting an accident among operators. Fingerprint has Ita function to recognize the operator's identity as well as password to the electronical Ignition key to the machine that not everybody can get acceses to operating the machine to start it up. Design of this electronically controled device is to produce biometrically engine start-up relpacing the currently recognize Ignition switch to crank and switch off the engine using microcontrolled ATmega328P sytem. Results of the study gained from the tests based on the standard operating procedures show based on the standard Operating procedures show a 100% success without any obstacles Keywords : biometric, starting system, mokrokontroller, fingerprint AbstrakIndustri alat berat merupakan lapangan pekerjaan yang dimana memiliki tingkat kecelakaan kerja yang tinggi, banyak kecelakaan kerja terjadi dikarenakan kesalahan operator alat berat itu sendiri, baik itu karena operator tersebut tidak memiliki kompetensi keahlian dalam mengoperasikan kendaraan alat berat tersebut, sehingga operator alat berat menjadi pekerjaan dengan tingkat kecelakaan tertinggi kedua setelah mekanik, itulah yg menjadi dasar penelitian ini dilakukan. Seiring dengan perkembangan teknologi elektronika digital dewasa ini, maka persoalan-persoalan yang dihadapi mampu untuk dipecahkan dan disolusikan yang dialami perusahaan terhadap para operator dilapangan, salah satunya adalah biometric authorization, yang diharapkan dapat mengurangi tingkat kecelakaan kerja didunia industri rental alat berat yang pekerjaannya memerlukan proses otorisasi para operatornya, dimana yang biasanya autorisasi tersebut biasanya menggunakan kunci kontak akan diganti dengan sidik jari (fingerprint). hanya operator yang telah terotorisasilah yang dapat masuk kedalam sistem tersebut untuk mengoperasikan unit. Sehingga diharapkan dapat meminimalisir kecelakaan kerja dikalangan operator. Fingerprint berfungsi sebagai identitas operator dan password sebagai kunci elektroniknya. Dengan menggunakan fingerprint seseorang tak akan mudah mengoperasikan unit dengan sembarangan karena hanya sang operator yang sudah terotorisasi yang bisa starting engine.
