Convert a standard wax candle into a realistic flickering LED candle. Candles are great for enhancing the ambiance of a room but they deteriorate when used and having a naked flame in your house can be dangerous. My goal was to preserve the look and smell of a traditional wax candle while overcoming their disadvantages. I've created a video detailing this process, take a look and consider subscribing to my Youtube Channel.

Step 1: Equipment

Tools:
  • Arduino Uno or Arduino Duemilanove with ATMega328 and breadboard to program the ATTiny85 microcontroller.
  • Soldering equipment
  • Hot glue gun
  • Utility Knife
  • Drill with spade bit
Materials:
  • ATTiny85 microcontroller. Other ATTiny variants will probably also work but this is the one I used.
  • 8 pin microcontroller socket (optional)
  • Orange LED.
  • Switch
  • 1 ohm resistor. This value is calculated based on the use of a 3v power supply and LED with 3v - 3.2v forward voltage.
  • Screw terminal (optional)
  • Small piece of proto board
  • 3v battery pack and AAA batteries.
Great job! Do you know if the ATTiny85 can control 3 leds? I've been wanting to try something like this: <br> <br>http://gadgetgangster.com/find-a-project/56.html?projectnum=229 <br> <br>That uses 3 leds to better simulate flicker and flame movement, but I haven't dived into Arduino enough yet to see if it's feasible.
<p>Its a shame the link doesnt exist any more as I would be interested in this. I shall have to do some research. ;)</p>
Amazing thank you so much
<p>Nice project, but it would be more realistic if wick is also moving </p>
Thank You!! :)
Great Idea, Question. I see a capacitor in one of the photos. How big? Where? And, why? <br>Thanks - Gary
This is amazing! Well done well done. Nice trick using hott glue as a &quot;flame&quot; it adds style and diffuses the light nicely
Cheers, appreciate the kind words. You can never underestimate the abilities of hot glue.
true true. it is a powerful tool/friend
Very nice! I can't wait to try this one!
Thanks! Post some pics of the results.
