Who says you need to have wires to complete a circuit? Use Bare Conductive Paint instead! Students get hands-on experience designing circuit routes on paper and then painting over them. Secure the touch board on the included LEGO base plate or similar building blocks to form an interactive low-current circuit. Connect to a computer and program with open-source Arduino to play music through the speaker. 15-piece kit includes touch board, 5 lights, speaker, paint, nylon tape, base plate, alligator clips, plastic organizer, and detailed instructions. Recommended for Elementary and up.
