In my last post I looked at using a servo motor with an Arduino and a couple of LED lights to indicate when it would rotate clockwise vs. counter-clockwise. In that post we were using a simple servo motor that had 180 degrees of rotation. We were using the write()…

I was playing around today with my Arduino, running the tutorial for controlling a servo motor. I decided to make it a little more interesting by adding a couple of LEDs. The tutorial uses PWM (pulse width modulation) to control the rotation of the servo motor. It starts at the…
