[vc_row][vc_column][vc_column_text]There are two types of relay,one is electromagnetic Relay, and this is actually the one for Linker Replay. The other one is solid state Relay (Linker SSR is of this type).  The driving capability of these two types are different.

1. GND of Linker Button -> Pin GPIO 0 of pcDuino
2. VCC of Linker Button -> Pin GPIO 1 of pcDuino
3. SIG of Linker Button -> Pin GPIO 2 of pcDuino
4. GND of Linker Relay -> Pin GND of pcDuino
5. VCC of Linker Relay -> Pin 5V of pcDuino
6. SIG of Linker Relay -> Pin GPIO 9 of pcDuino
7. GND of Linker LED -> Pin GND of pcDuino
8. SIG of Linker LED -> COM port of Linker Relay
9. NO of Linker Relay -> PIn GPIO 13 of pcDuino

int S_pin=9;

void setup() {
// put your setup code here, to run once:
pinMode(S_pin,OUTPUT);
pinMode(butten_pin,INPUT);

pinMode(0,OUTPUT);
digitalWrite(0,LOW);//Use GPIO pin 0 foot as GND

pinMode(1,OUTPUT);
digitalWrite(1,HIGH);//Use GPIO  pin 1 foot as VCC

pinMode(13,OUTPUT);
digitalWrite(13,HIGH);//Use GPIO pin 13 foot as VCC

}

void loop() {
// put your main code here, to run repeatedly:
digitalWrite(S_pin,digitalRead(butten_pin));
}

//When press the button, hearing  the sound of the relay  stiring  up, led will light
