This project consists of building a microchip that will output a PWM signal, that is consantly being updated VIA given input parameters.
The chip is already completed, it has the ability to controla servo motor 60 degrees in both directions flawlessly. The problem is that I was using a servo for the prototype and it works. However, the motor that it now needs to be used on, is some sort of brushed DC motor.
I know for a fact that the brushed DC motor does what I need to do, because it is off of a car and has already worked, but it only had two inputs so it puzzled me. I did a little reading and and apparently it operates with the supply voltage and the PWM signal together?
^ pre info
--------------------------------------------------
Ok so, what I have, a PWM signal and a supply voltage. The car manufacturer states that it uses some sort of H-Bridge to mesh the PWM signal with the supply voltage. I guess what I'm getting at is how can I build something similar to this, and what will the output look like to the motor.
If i'm unclear in anyway feel free to tell me I didnt explain it well.
The motor i'm using for the final prototype has the ability to be controled to a 45 degree rotation and hold its position with just two I/O pins. I just need to know how this is being accomplished.
Thanks a lot; you guys are always helpful.
