Artifical light source with natural candle behavior. Made of red, yellow and/or orange LEDs.
Turned on by "matchstik" light contact (can be capacitive sensor affected by massive metal object, or inductive frequency sensor).
Turned off by finger - capacitive sensor, microphone. Microphone allows candle to be turned off by wind, but also makes it sonic
Program shoud simulate candle fire with PWM on LEDs, random numers proccessing, some value limitations of parameters.
Advanced - torch flame simulator light (with accelerometer), camp fire or kerosine lamps simulator.
