Data Sheet

// the setup routine runs once when you press reset:
void setup() {
// declare pin 5 to be an output:
pinMode(MotorControl, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(MotorControl,HIGH);// NO3 and COM3 Connected;
delay(1000);
digitalWrite(MotorControl,LOW);// NO3 and COM3 Disconnected;
delay(1000);
}
When Digital 5 set high, NO3 will be connected with COM3. The motor will work and the 3rd Relay Normally
Open Indicator will be lit. Otherwise, Digital 5 set low, NC3 will be connected with COM3. The motor will not
work and the 3rd Relay Normally Open Indicator will be off.
Digital 7 --> COM1 , Digital 6 --> COM2 , Digital 5 --> COM3 , Digital 4 --> COM4.
