BlinkM MaxM, preferred Arduino connection

Note, you can run simple tests with the MaxM directly hooked up to Arduino like a regular BlinkM, but it's not very reliable: the poor Arduino chip just can't power those big LEDs on MaxM.

 

The solution is to either use a small breadboard and run power from the Arduino board's power supply to it (instead of powering it from an Arduino chip pin) or pop off the Blaster LED board temporarily.
