(...) How long did it work before? Have you checked the solder and socket connections of the chips in the circuit? Sometimes chips shift in their sockets and incur additional impedance in a connection, causing problems. Is your board subject to (...) (28 years ago, 12-Aug-96, to lugnet.robotics.handyboard)

(...) One thing to note, not all servos are designed to turn 180degrees. The ones designated as "retract servos" are designed to turn 180 degrees, the rest are designed for something around 90degrees. Most can be modified to turn as far as you want (...)

(...) You need to go into the servo.c file, and adjust the minimum and maximum frequencies the servo can handle. If you open servo.c, you'll find instructions as to how to do this. You pretty much just have to adjust the program to suit your servo, (...) (28 years ago, 10-Aug-96, to lugnet.robotics.handyboard)
