Pololu RC Switch with Relay

Hello.

It looks like you are only sending one pulse width in your second program, so the state of the switch will never change. Try using this for your loop:

void loop() {
  myservo.writeMicroseconds(2000);  // Send 2ms pulses for 5 seconds
  delay(5000);   
  myservo.writeMicroseconds(1000);  // Send 1ms pulses for 5 seconds
  delay(5000);     
}

If that does not work, could you post some pictures of your setup that shows all of your connections?

For future reference, if you want to operate a relay using a digital signal like in your first post, you could just use a basic relay carrier, like this product:
