Hi Everyone, Thanks for the input, I probably won't get to experiment with the encoder until next week unfortunately. :( Brendan, the mouse I have only has one encoder per wheel, but I will test out the circuit and see what I come up with. Also, I usually do delete my address in the reply to field. I must have forgot, at least I remember the topic tags !!!
