Hey, here's my problem:
I have an assignment, and the i have 2 problems that are killing me, but for now I want to address this one ---> "Draw the complete schematic for the current limiting, computer controlled, motor controller, including all circuit modifications."
The problem I'm having is (apart from the having not reference material to fall back to) is we've only used comparators, NPN transistors and relays to control DC motors but the lectures on how to use them properly is poorly taught so i'm left figuring it out on the spot.
We have been fiddling with some programming in C, using Turbo C.
The parts available are:
Parallel port (DB25)
LM339
2N3904
1N4001
Relay DPDT
Various Resistors values
and of course the motor.
This is the best I can do to explain where i am with this problem. All any any help is appreciated! Cheers, mates=D.
