Do you know that the red wire from a battery corresponds to Vcc and the black wire to ground? I guess you do. I did. Turns out the guys who created my lead-acid battery didn’t.
I was working on a H-bridge and suddenly it got fried. I checked out the wiring and since everything was color perfect, I attached another H-bridge. And then the second one got fried. After much cursing, I finally debugged the error with a multimeter. To cut a long story short, I have two less H-bridges this morning than what I had last night.
Note to Self – Always check with a multimeter. Thank Thor for not screwing with my development board.
