Thats the exact problem I'm having. I would like to have 1 RCX be able to
control the direction of 2 motors. So what I trying to make is a 4 button
controller using 3 touch sensors.
For instance, I want to have 1 RCX control the opening and closing of the
claw, and the rotation of the wrist.
It is even theoritcally (my spelling stinks) possible to use 3 touch sensors
and control both forward and reverse of 3 motors.
Like this:
Given Touch sensors A, B, and C
and Motor outputs 1, 2 and 3
Depressed Switches
A: Forward 1
B: Reverse 1
C: Forward 2
A+B: Reverse 2
A+C: Forward 3
B+C: Reverse 3
I started working on a controller which allowed 3 sensors the ability to
control both directions of 2 motors, but i'm sure it will take more time.

| (...) You should be able to get 3 sensors to control 3 motors like this: Sensor A not pushed = forward Sensor A pushed = reverse Sensor B pushed and not C = Motor 1 Sensor C pushed and not B = Motor 2 Sensor B and C pushed = Motor 3 -Kyle (22 years ago, 10-May-02, to lugnet.robotics)

| By making a good programming you can control lots of functions with one touch sensor, wich would be complicated but it's possible. I have tried using two touch sensors to control motors, let's say you press the sensor once for motor A, twice for B, (...) (22 years ago, 10-May-02, to lugnet.robotics)
