I finally figured it out which is generally better for learning this new language for an old dude. Great sketch and it helps me to learn! Thanks for sharing. Cancel request!

I am in my 70's and the picture on the site is not quite clear enough. Going by the code did not help. Also, if time permits, I could not find out how to determine the min/ max PWM values for a 6 volt 150 ma motor. Thanks very much.

I wrote some PID code for the arduino to make it all work. There is better code in the an arduino PID libarary these days, but hopefully the info is still useful. http://abigmagnet.blogspot.com/search/label/PID I messed around with controlling DC motors using the encoder strips and sensors from ink jets a while ago.
