Introduction

The DFRobot Single Relay blocks the number of electronic modules. It can be used in interactive

projects. This relay shield uses Omron G5LA high-quality relay. It can also be used to control the

lighting, electrical and other equipments. The modular design makes it easy to expand with the

Arduino board (not included). The Relay output state by a light-emitting diode. It can be controlled

through the digital IO port, such as solenoid valves, lamps, motors and other high current or high

voltage devices.

i

int Relay = 3;

void setup()

{

pinMode(13, OUTPUT); //Set Pin13 as output

digitalWrite(13, HIGH); //Set Pin13 High

pinMode(Relay, OUTPUT); //Set Pin3 as output

}

void loop()

{

digitalWrite(Relay, HIGH); //Turn off relay

delay(2000);

digitalWrite(Relay, LOW); //Turn on relay

delay(2000);

}

Result

Every two seconds, LED will be turned on and off.
