Pymcu is Fun.

I started to the use the pymcu device.

What a cool little device. I have been using it to modulate the speed of fans for testing power usage on a server.  I really find the pulse width modulation feature very simple to use. It help me get my job done.

I think I am going to have some fun with this with my son on some school projects.
