Quick and dirty candle effect with PIC12F675

For best results use a clear amber LED, you can embbed the LED using a tube as cast and pouring molten parafin...

Thanks for your code example. It would be great if you could include a schematic. Because there is no shematic i cant put this in the User Projects section, but i have put the code example in the wiki here

Thank you for your contribution

The schematic could not be more simple ;)
As an alternative you can omit the switch and use an old USB cable to provide the the 5vdc (usually RED cable) and the Ground (usually BLACK cable) this way you can have a romantic companion for your computer...

Code:
