Wow ! man I was gone!
Decided to dust out my old AVR v1.5 and give it a whirl!
Works! original v1 22hz crystal firmware by Tronic. LCD runs, displays 128-128-513-523.
when pot is moved to either direction the number changes, when I connect second pot the board freaks out.
Can't say same for the H-Bridge V1.2b.
at first all all output LED's worked according to what I moved the pot, suddenly motor 2
green light quit, just the red would light up. Cool, replaced IRF4905L had extra 4, worked for a sec.
Now got new Symptoms:
motor 1 produces 11.79 volts at full bright RED LED (pot full turn on one direction), and Only -2.54 at full GREEN LED (pot full turn in opposite direction)
Motor 2 Produces 11.79 volts at full bright RED LED, and when I move pot anywhere past mid position towards opposite turn stays at .28 volts.
No motor are Attached just multimeter!
And at last Buddy just quit, No LED's reacts nor any voltage is read on the motor out.
I can read 12 volts on the motors supply.
So, I'm out of Extra parts!!!
But I do Have an MD03 here is the link:http://www.robot-electronics.co.uk/htm/md03tech.htm
Can I use Tronic's Avr to control the MD03?
Got 2 laying around, but can't get my head around how to connect them to the AVR.
I see pololu h-bridge are being used, will be ordering soon.
Thanks in advance!
