By using an Arduino Uno and a single-channel relay module, you can control high-voltage or high-power devices, such as lights, motors, and appliances, from your computer or mobile device. In this blog ...

The relay module will need 5V from Arduino to power up and will get input from four different digital pins of the Arduino. Now let’s connect the relay module to your home appliance. Take the positive ...

Controls power in AC load through a TRIAC, performing AC phase cutting with help of a zero-cross detection circuit in a dimmer module. The module used was a RobotDyn AC Dimmer module paired with an ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

In this Lora project, I have shown how to make the LoRa Arduino ESP8266 control relay using the RYLR896 LoRa module with real-time feedback. So after turning on and off the appliances the receiver ...

The receiver is built around Arduino Nano (Board2), Yoda module (YM2), Yoda adaptor(YA2), 2-channel relay module(RM1), and 5V DC power adaptor. Here, the Yoda module acts as an end-node module. The ...

Temperature Controlled Fan Circuit Diagram. The complete circuit to build the temperature controlled fan using arduino and lm35 project is given below, we have used fritzing software for making most ...

My setup is a relay on the 240V line, a programmed temp swing of 5deg, and cool down period of 5 minutes after ac shutdown before it can turn on again to avoid damaging the compressor.
