I want to see if it is possible to drive a Power Functions motor both with variable speed and forward/reverse with my own power source. I am planning to use my own power source, an IR receiver and a motor.
[Power Source] -> [IR Receiver] -> [Motor]
As I understand it, the pin out for Power Functions is as follows:
- C1 +/-9v
- C2 +/-9v
Which of the above pins would I need to power to achieve this?
Do I need to provide a constant 9v to the IR receiver for it to function?
Can I rely on the IR receiver to vary the speed of the motor?
What would happen if the IR receiver was powered with less than 9v?
My power source may not always spin fast enough to develop 9v so I am wondering what would happen in this case.
P.S. I am returning to this hobby after 25 years so not entirely up to speed on how all of the new "stuff" fits together!
