That code could still trigger multiple events due to contact bouncing. I would suggest setting a minimum elapsed time before letting the button trigger another event. For example:

Code:

unsigned long lastTime;
if(digitalRead(buttonPin2)==HIGH)
{
  if (lastTime+250<millis()) {
    Setpoint+=1;
    lastTime=millis();
  }
}

That way, you can click the button once, and it'll increase one degree, or hold it down to increase at a rate of 4 per second. With a bit more coding, you could have it count how long the button stays down, and after say, 2 seconds, have it increase the rate of change.

Thanks for the code! I plan to use it to control multiple servos without having to use delayMicroseconds() for each one.

I would suggest using a specific value for the servo based on the distance.

For example:

Code:

if (inches >= 3) {
   digitalWrite (ledPin, HIGH);
   pos=45;
   myservo.write(pos);
 }
 else {
   digitalWrite (ledPin, LOW);
   pos=135;
   myservo.write(pos);
 }

You might also try putting in an even longer delay than the suggested 4 ms. The servo library may react badly to having the write commands come in too quickly.

I trust you've grounded the receiver and the Arduino together? That's vitally important. Without that ground, you will never receive anything at all.

I love the idea of the TellyMate Shield. I may need to buy one, but I've got one question... What about adding an LM1881 or LMH1980 sync separator to allow the TellyMate to overlay on top of pre-existing video? I'm honestly not sure how hard that would be to do, but it would add a whole new world of useful applications to the TellyMate. For example, live GPS overlay over a video signal.

Wow! I've been fascinated by PID controllers ever since I found out what they were, but have been scared off by the math. This looks like a really useful piece of work. I'll have to find a project to use it in!

I bought the JYE scope from Seeedstudio a couple months ago, and I've been quite happy with it. I haven't had time to get in depth with it, but I'm planning to use it to capture IR codes. For the money, it's a great tool.
