Just wanted to ask, if any had some good motor controller that also worked when they etc. put it together with a PIC or other mikro controllers. And if you have, if you would be so kind to post a schmatic of how the motor controller and CPU are connected :0)
In my projekt, the motors i am using can max handle about 4.5Vdc, and are dwaring about 2.5Amp when stall.
Do you all use a opto-cobler between the "brain" and the motor controller?
For now i have spent about 1-2 months, trying to get my robot projekt to work. The motor controller work alone, and my PIC16F876A + a Sharp sensor also work alone. But when i but it together it wont work.
Right now i am trying to get it to work with the motor controller for LMR Mr. Basic. Also using the MR Basic chassie + motors.
If you want any more info, or got any questions just say so, and i will see if i can answer them.
Optocouplers are not necessary. But powerful motors like that draw a lot of current from your power source. If you use batteries, you’d better use separate batteries for motor and controller. Make sure to connect both grounds, so that 0 Volt is the same level for all components.
