Resistive joystick replacement
Archiver
Posts: 46,084
I am looking for ideas and options if any of you have them. Any help
would be greatly apreciated. I have a resistive joystick on a motor
controller, ( formally a wheel chair controller.) The joystick
basically has two 2.5K pots in it, one for the left motor and one for
the right. When the joystick is centered or neutral, the wiper arm
is at 1.25K on both. I also could compare it to a variable voltage
divider. I am looking to replace the joystick mounted on the box
with a Basic stamp. I already have a basic stamp doing other
functions in the robot, but I was planning on adding one to handle
the motor control, and reception of the command signals when the
robot is not in automatic mode. Remember this is a tinkering and
experimentation project, so multiple controllers is okay with me. I
am looking for ideas to have the nbasic stamp simulate the two 2.5K
pots, any ideas? The controller for the motors handles all the H-
bridge, PWM and power issues, so input to it is all that is left.
Once again, any ideas or input would be greatly apreciated. Thanks,
RPW
