DIY Candle Simulator

Candle light is usually warm and waves slowly with the random oscillations of the air in the surrounding environment. It should be possible to simulate the effect of a candle with a small electronic circuit that generates random patterns or numbers. Here is a simple such circuit shared by Embedds member.

To create the candle effect you will require two LEDs and a small PIC12F675 microcontroller from Microchip. LEDs can last at least 10 years and provides more intense light with less current than a light bulb! You can control the LED brightness using PWM modulation. Hex files, required to program the PIC microcontroller, are available for download.
