I made this quiz box on gunpei yokoi he is japanese and he created allot of hand held game consoles it took me a while because doing the wires and connecting it all up was a little hard mostly stripping the wires was hard but it was worth it. It works well and this would be cool to do again. 🙂
It works by the metal pins on the box when you touch the wires on the right answer it will light up because there is allot of wires connected on the back to the right question and the right answer. Once you have touched the wire on the right one the light bulb lights up yellow 😀
