So I have a [few of these these laying around and I want to figure out how to make it work better for low speed / low duty function of a 12v motor. The motor draws 0.2A at 4v at the lowest speed with a high quality PWM controller. The controller I’m interested in will get it kind of slow, but not slow enough. Also, the motor is very noisy at low speed with the dale wheat controller.
Any help would be good. It has a AVR Tiny chip on it.
I’ve also attached the code, and below is a link to the schematic.

I did email Dale, and he is fine with me modifying this. That is why he keeps everything public. He doesn’t have time to mod for people so he gives all the info away.](http://http://www.dalewheat.com/tag/12v-dimmer-kit/)
