Hello all,
I have a brushed DC motor that works nearly good enough. I've been using a timer to control when to start/stop the motor. However, after a period of time, the error accumulates and becomes large.
I'd really just like a third wire on my brushed DC motor that pulsed everytime it did 1 revolution. I could then count the pulses on my microcontroller to determine when to stop.
The problem I have is the cheapest method I currently have found are continuous servo's, which run around 10 dollars, and I have to send commands to send it in different directions.
Does anyone know of a place that sells cheap brushed DC motors that has a built-in hall effect sensor or something?
Thanks!
Bill
