Arduino Candle with remote control

We have lots of light sources around us. Most of them are electricity based – lamps, flashlights, screens. But some time ago one of main light sources were candles. This is amazing, that candles still are popular due to several reasons. They create intimate climate, serve as emergency light, improve odor, and is attribute in many celebrations. The fact is that we love burning candles and probably will continue doing so. Speaking of electronics, candles are great inspiration for many projects. There has been many attempts to build electronic candle with various effects and colors. Some of them try to mimic candle flame flickering, other focus on design and functionality. Jose Daniel Herrera have built his own version of candle. He’s chosen RGB LED strip as light source which is controlled with Arduino Pro. Project was housed inside IKEA lantern which already has candle shape in it. He programmed several effects like rainbow, fade and fire. He wanted easy way of switching between modes, so he used an IR remote control. With a button press you can select any effect… Continue reading

LED candle that fits tealight case

We have seen several LED candle projects around. Their main purpose is to imitate real candle burning. Some of them generate flickering effect using pure code generated random number, other use sensor to sense environment like ambient light variation. It is up to you to judge which of them tend to be more realistic. akafugu made very simple LED candle that runs on Attiny13A microcontroller. It drives single 1W LED. It can be turned on and of fusing single push button. Also there are two flickering modes – high and low intensity. Candle has a base shape of tealight and is powered by single CR2032 battery which ensures operation for about 40-50 hours. Continue reading
