Let's see. First, I'd like to put a pair, if possible, of shaft
encoders on my robot. (It's annoying not being able to tell how far I've
gone!) Anyways, digital inputs 7 and 9 are being used by a 6500 Polaroid
sensor and an RC servo. Is it still possible to use shaft encoders? If
not, is it possible to move either the sonar or servo signals to another
port/line?
