When we design projects by using , there are a lot of equipments with large current or high voltage equipments (such as electromagnetic valve) which usually cannot directly controlled by digital I/O interface,then we can consider solutions based on relay.
This relay output driver shield adopts Omron G5LA relay to supply 1 channel control, the max can link to equipment with 250V AC/DC, therefore it can be used to achieve so many effects,such as electric lamp control.
Modular design makes it easy to connect with The output status of Relay are shown by a light diode for convenient using.
Test Code :
int Relay = 0;
void setup()
{
pinMode(Relay, OUTPUT); //define PIN0 port as output
}
void loop()
{
digitalWrite(Relay, HIGH); //Realy Close
delay(2000);
digitalWrite(Relay, LOW); //Relay Open
delay(2000);
