This is PWM controller I bought for speed control of DC motor:
DC motor rotation direction is controlled using switch: when switch is in position I motor rotates in one direction and when it is in position II motor rotates in opposite direction. Since I need to have limiters also, I removed this switch and shorted controller on this way:
Instead of only motor, I put on output of controller DPDT switch, limiters and motor. It looks like this:
Here is schematic:
Now I can change direction of rotation using DPDT, I have also limiters and of course I can control speed. My question is, is it possible to remotely control direction of rotation instead of manual control using DPDT?
