This robot scuttles on two modded servo wheels when the lights are on, but stops when the lights are off or the robot is covered. When switched to song mode, a pushbutton cycles through songs. It plays "Don't Fear the Reaper" (Blue Oyster Cult), "Snow" (Red Hot Chili Peppers), or no song at all. There is also a blinking LED indicator. The speaker's voltage is regulated by a DAC chip and pulsed by a timer, and the speaker and corresponding board come from an old radio. The board is controlled by an eZ430-2012 microcontroller from Texas Instruments and is powered by 4 AA batteries through a 3.3V regulator.
