Heart Box

"Heart Box" was made in a Tic-Tac container. I was inspired by a schematic schowing how to make an LED sensitive to light. There are four photocells that each control two LEDs. The darker it gets at night, the brighter the LEDs shine. Last year, my wife joined  the volunteer 
Emergancy Medical Service for the town we live in, so it was a gift to her. Go Katie!
