LED Candle
Posted by admin on September 23rd, 2008
As you can see, the candle is run from a PIC12F675. This is an 8 pin microcontroller with 5 I/O lines. I decided to run the candle from 4 AA batteries, giving me a 6 volt power supply. The battery holder provided a nice base to help the candle remain upright. Because the PIC requires 5 volts, I added a 1N4148 diode that has a 1 volt voltage drop, thus providing me with 5 volts. I used five 15,000mcd LEDs (very bright) to give me a bright flame. This makes the candle much brighter than my storebought candle. I also used 5 LEDs as it gives a much more realistic flame, looking more “flickery.”

This is not a bad little project, but a number of Chinese firms have built application-specific ICs to handle this. You can read about them in my guide to flicking lights, http://www.45mm.com/lighting/flickering.html …
