No, that's not it. Like I said I'm pretty familiar with using a pot. Even before I ever had an arduino I had electric guitars, lots of them. Besides, I checked with a meter and I was getting a nice variable voltage with my meter, just not on the serial monitor. Maybe my arduino sustained some damage when I burned out that H-Bridge, because the sketch is right as well. Is that possible, for just one part of the IC to be affected? I have an olimexino stm32 that could stand in should this be in need of a new microcontroller. I also have a brand spanking new Mega2560 that I haven't used yet
I haven't had time to verify whether my Atmega328 is damaged or not. The only way I know to check it is to hook it up to my Mega and see if it works there. I got a box of solar cells today, so I'm a bit preoccupied 8) But, just looking at my sketch, will it work? Anyone else using a motor shield?
I'm thinking of doing what I did last time I did something like this and just building a simple driver board and hooking that directly to a parallel port being controlled with EMC2. It worked perfectly, this motor shield business seems to be making things harder, not easier.
