Hi To solve your problem you don't need to learn s19 code. You must only something like encoder0_low_threshold= 75; in your program (c and nod s19). You must only replace the 0 (zero) according to your used analog port. For further information refer (...) (23 years ago, 22-Aug-01, to lugnet.robotics.handyboard)

hi, I am using handy board to control my robot. In order to implement dead reckoning, I brought a pair of shaft encoders which give 1000 counts per revolution.

Hello again, I was surprised to find that my expansion board servo ports were putting 9 volts. Is this the way the board was designed or is this in error. Most servos I have come across work in the upper 4 to 6 volt range. The servo I have runs (...) (23 years ago, 15-Aug-01, to lugnet.robotics.handyboard)
