Roadblock
Posted: Sat Jul 29, 2017 11:52 pm
I seem to have hit a bit of a roadblock and I'm not quite sure what to do now. With both my SeeedStudio and my PCBWay boards, which are essentially the same, everything sort-of works, up to a point. I have the LCD user interface functional, select a file (so the SD card is operational). The motor starts, the disc stars spinning, the LED lights flash appropriately, the disc gets up to speed, and then - it all stops. I have a feeling it's at the point where the PWM for the disk becomes 0, and the disc starts free-spinning (to slow down). At that point, I guess, there's some disc-as-a-generator happening and perhaps I'm getting some sort of back-current resetting the Arduino...? Dunno. I have a diode on the motor.
