CUM_MATRIX

(Champaign-Urbana Mass Transit District + LED Matrix)

CUM_MATRIX combines the CUMTD API, a 64x32 LED matrix, and a Raspberry Pi to create a mini timetable of CUMTD bus departures. The board refreshes every 30 seconds and cycles between two screens with two times each, similar to a real timetable.
