Note that all microcontrollers, which includes an arduino, must be
powered from the superpro protoboard, and it can only supply
something along the lines of 8mA. A stock arduino will draw 20mA,
so we ran a barebones ATmega328 to drive the led strip.

I remember reading in the new game manual that external 9V ARE allowed this year.

All power used in the circuits connected to the Prototype Board must be derived from the power
connections provided within the board including the board’s optional additional 9V battery.
If this is the case ya'll CAN use your actual Arduino with a 9V power. Thoughts?
