RGB LED Shield Kit

This Arduino-compatible shield uses three TI TLC5940 PWM LED driver ships to drive a 4x4 array of RGB LEDs. Each color is controlled by a different chip so you can adjust the reference resistors for the appropriate current. This also includes mounting positions for for three general-purpose buttons that are connected to ground, and a reset button. The TLC5940 chips are not directly connected to any Arduino pins, but a header is provided for you to make a manual connection depending on the needs of your sketch.

Model: OSK101E1P

This board is a version of the circuit used at the first HTINK workshop on March 14th, 2009 at Bug Labs in New York City.

The best library I've seen for interfacing with the TLC5940 chips used in this shield is the tlc5940arduino library. We used it in the HTINK class and it performed very well.

On the shield, the four LEDs at the corners are labeled with their X,Y coordinates: "1,1", "1,4", "4,1", and "4,4". The formula to turn a coordinate into a LED number is (X - 1 + (Y - 1) * 4).
