This was made for kids to climb a rock wall and they get to push a light up button at the top. Used an Arduino with a 5 sec delay and small LED strip. Parts that are needed will be bass threaded inserts 3 or 4mm, springs and a large surface mount push button and a 10K resistor, 9v battery pack and there is a small space for an on/off switch. The small button spacer is to be glued on the top of the button.
