start with morphing plasma, but allow going to color cycling if desired.

Power to the board is either via pin headers or a set of mini screw terminals.
ARDUINO LED MATRIX DRIVER DRIVER
Without any external circuits, play and shine.
8 bits colors support with 6 bits correction for each color in every dots.Colorduino is easy to cascade by IIC and Power interface.
The ATmega more CPU bandwidth for performing other tasks. By using the DM163, the Colors shield gains three 8+6-bit channels of hardware PWM control of the LED’s freeing up the MCU from having to implement it in software. Colorsduino pairs the M54564 with a single DM163 constant current driver. This design is to make user easily modify or write the firmware ofĬolorduino by Arduino IDE. The Colorduino is a RGB LED matrix driver platform basis on ATMega 328P.
