PWM Expander (RGB LEDs/Servos)
This project is a PWM expander for arduino allowing you to use the TLC5940 chip from TI to make a set of cool PWM LEDs or servo's obey your commands!
This board is the basis of loads of cool projects, it allows your arduino to control more than the usual few PWMs, this has 16 and can daisy chain many chips together with minimal effort.
There is a shield PCB version which I am trying to build and test at the moment but as you can see in the image gallery the first attempt was a bit botched :(
The build is quite simple, just plug it all in and programme the board.
