Pro-150 Push Button Use

If you need to control a Pro-150 via forward / reverse push buttons, a neat way to do it is to use the Pro-150 in joystick mode.

This diagram shows how to wire it up. The pot wiper teminal is held at 2.5V by the 2 x 4k7 resistors, and the fwd / rev switches pull the wiper voltage up or down as required.

The Pro-150 should be programmed by following the instructions here.

With a speed pot of 10k, the speed can be reduced to around 10%.

The diagram shows how we arranged control for two Pro-150s, the diodes and Rev_both switch were included to allow single handed reversing.
