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!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
