This is a 3D printed maze that uses the micro:bit to time how long it takes you to complete it! Challenge your friends! Write a code that times how long it takes you from unpressing pin 1 (start of the maze) to pressing pin 2 (end of the maze). This design uses a 3D printed ball coated in conductive paint and lines of conductive paint from the front of the two holes in the 3D printed base to the ground pin. Threfore when the conductive paint coated ball rests in the hole it completes the circuit and presses either pin1 or pin2.
