Here, we are using a 4 relay module because we will only control four appliances. If you want to automate a different number of appliances, you can use a different relay module. There are many relay ...

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.

SIM900-Arduino-Relay-Control This project uses GSM Module (SIM900) with Arduino to switch Relay state by SMS OR CALL.

This project demonstrates how to interface a relay module with an Arduino to control high-voltage appliances safely. The setup involves using a relay as a switch, allowing the Arduino to control ...

Simply, it’s an Arduino library for communicating with Modbus slaves over RS232/485 via RTU (remote terminal unit) protocol. In conclusion, the Modbus 2-channel 5V relay module is a very useful device ...

The RGB LED module lets you make all sorts of colors with just four pins from the Arduino. Learn how to do it here!

Arduino and L293D Circuit Diagram Now that we have completely understood how the L293D motor driver IC works we can connect all the required wires to the L293d Arduino, and we can write some code to ...
