Christine Lee – Light-Sensitive Bomb (with timing)

This simple circuit keeps track of how long (shadowTime) the light is dimmer than an arbitrarily defined level; when shadowTime is longer than an arbitrarily defined period of time, the bomb will “detonate” in the form of colorful LEDs, preceded by a single “beep” sound, also in the form of an LED. The timer resets to zero whenever: the bomb “detonates”, OR when the light is brighter than the arbitrarily defined level. The circuit is quite simple; the coding is slightly less so.
