These candles flicker like a real candles and can be activated with an actual flame
Story
Flame (or heat) detection relies on the temperature dependence of the LED's forward voltage. This voltage is measured (at very low LED current) by the internal ADC of the PIC12F1501. If the LED voltage remains below a predefined threshold for a sufficient period, the LEDs activate and begin to flicker. The large candle, containing four LEDs, is powered by a Li-Ion battery and includes a USB charger (MCP73831). The small candle, equipped with a single LED, is powered by a CR2032 or LIR2032 battery. The small candle can even be extinguished with a touch of your fingers.
