Product overview

In 2014, the latest Arduino Relay shields digital Relay module using high-quality Relay, ningbo remit to provide all the input and output functions, integrated dynamic module, Relay operating state can be shown, the AD hoc fly-wheel diode protection, highest can pick up 250 v / 3 a communication or 30 v / 3 a dc equipment, so can be Roboboard controller, the Arduino controller to control, the weak current control is transformed into high voltage control. When using Arduino design interactive work, a lot of heavy current or high voltage equipment (such as electric fans, etc.) are usually not directly with the Arduino or other digital I/O interface of single chip microcomputer control, then you can use the digital relay module through the 3 p Sensor cable directly into the Arduino Sensor shields V5.0 Sensor extension board or Arduino MEGA Sensor shields V1.0 extension board special Sensor, it will help you solve this problem, has been making interactive work, a necessary choice.

Application of routine

sample program

int Relay=10 ;                    
void setup()
{  
      pinMode(Relay,INPUT); 
}

void loop()
{
    digitalWrite(Relay,HIGH); 
    delay(1000);                  
    digitalWrite(Relay,LOW); 
    delay(1000);                
 } 

Application effect

The CA, AB end of the relay will be in conduction, continuous cycle.
