Thanks Bill and Audio guru for your help on this.

Looks good. Which schematic did you use?

 

yours.
A great PWM circuit it is...

 

How warm are the part getting? The MOSFET should be cool, the LEDs warm to hot.

 

yup. The MOSFETS are cool and I won't be using any heatsinks on them. The LEDs are getting a little too warm without heatsinks. I think the smoke I mention in the video is residue flux smoking off of the blue leds. I am waiting for my 10W 500Lm 12vf 1A LEDs from Hong Kong and they will be on beefy heatsinks. Right now I am just working on the coding and features of the programming.

 

Yeah, this has been my experience. If the MOSFETs get hot something is wrong, but when a device that drops 3V give or take pulls an amp or more there will be heat.

Are you going to put this in the The Projects Collection?

 

I don't see why not. I will do a write up of it in a couple of days and put it up. I am kind of pressed for time write now with the coding. I have a lot of new syntax to learn and implement by Tuesday.
