The module is uses SRD relay module to control high-votage elecrical devices. (maximum 250V).It can be used in interactive projects and can also be used to control the lighting, electrical and other equipments. It can be controlled directly by a wide range of microcontrollers and can be controlled through the digital IO port, such as solenoid valves, lamps, motors and other high current or high voltage devices.

Schematic, Wiring

Demo Code

int Relay = 3;
void setup()
  pinMode(Relay, OUTPUT);     //Set Pin3 as output
void loop()
          digitalWrite(Relay, HIGH);   //Turn off relay
          digitalWrite(Relay, LOW);    //Turn on relay
