NEW TUTORIAL: LED candles: simple, easy, cheap

LED candles are very common these days. It’s easy to see the attraction — there’s no fire danger and they never need to be replaced (just batteries). But there’s such a wide variation in price and quality that it’s hard to know what to purchase. Some store-bought candles flicker very realistically, others just seem to blink. Some use plain white LEDs, some look like real flames. And there’s no way to know how good a candle will look without buying it.

Thankfully, with Adafruit’s Gemma microcontroller and an RGB LED pixel, making your own LED candle only takes a couple of minutes. Because the LED can create any color and the Gemma can control the flickering very precisely, it will look better than any store-bought candle ever could. Because the parts are so cheap, it will cost much less too!

See the full tutorial here.
