Maker: Ben Combee

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.

Note:
Pin selection is determined by the user: the buttons and FTDI chip signals are connected through jumpered headers to allow reassignment so the shield can be used on the Mega or stacked with other shields that need those pins.
