Ouch!
That’s not fun frying stuff, but like you say, you do learn. I just noticed the “wheelchair” thing. If driving those kind a motors, you may be looking at these h-bridges instead of the ones you got. I’ve been wanting to try out those Simple-H ones on a smaller bot, but haven’t gotten that far yet.
Did I mention that micros are a lot cheaper to fry? (running and ducking)
Yeah - I first looked at the
Yeah - I first looked at the OMSCs - but i thought i could squeek by with the simple-H’s, I have a tendency to buy cheap and pay for it later.
Ha ha ha… good point - maybe i’ll come around when I stop laughing/crying

discrepancy
Grog,
There appears to be a discrepancy between your circuit above and the one in the great tutorial from dprg. Today I tried to draw a 555-based pwm generator in Eagle and I discovered that you did not pull up the discharge port (pin 13 in your case). The 10k resistor is “supposed to be” connected with V+.
I have no idea how this affects the circuit.

Good catch Rik!Thanks, the
Good catch Rik!
Thanks, the problem was the diagram - the actual circuit has it connected to V+ correctly. I’ll update the diagram and post it here for reference, a little later.
Workin on passive parallax webcam ranging - it’s going quite well at the moment … can’t stop
