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 ...

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 ...

Here we have used 6V Relay module. Here to turn on the Relay with Arduino we just need to make that Arduino Pin High (A0 in our case) where Relay module is connected. Below given is Relay Driver ...

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 ...

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 ...

This project uses GSM Module (SIM900) with Arduino to switch Relay state by SMS OR CALL. Step 1 (Connect SIM900 With Arduino) Use picture as a reference for connecting SIM900 to Arduino.
