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

Here we have provided PCB layout, circuit diagram, and Gerber files so that you can build or directly order this Relay Driver Module. Previously we have built 4-channel Relay Driver Module, but this ...

A simple Arduino project to work with Single & Dual Relay modules with ESP01 ESP8266 With Simple http page & ArduinoOTA support to upload code from Arduino IDE wirelessly - No need to remove from ...

Power on the receiver circuit next and wait for five seconds as defined in receiver code. Press pushbutton (S1 or S2) in transmitter circuit to control the corresponding relay in receiver circuit.

This can be done through relay modules and turning your Arduino into an electronic switch. Then, by using a board with wireless capabilities (like UNO WiFi Rev2 or RP-2040 Connect) or adding ...

This system is implemented using the NodeMCU ESP8266 Wi-Fi module, Arduino Uno, 4 channel relay module, temperature sensor (DHT 11), LDR and PIR sensor. The system can control home appliances both of ...
