A self-igniting candle implemented using AVR and PIC microcontrollers.
This project has two variations, one using an ATTiny25, the other using a PIC12LF1822.
In a series of minimalistic devices, this electronic candle periodically measures ambient light levels. Once it detects nightfall, it self-ignites and burns for three hours, flickering as a candle does. The flicker intensity changes about every minute, adding more variability.
