Alex Lechkin sent in this cool electronic candle project he made using ATtiny13V
Why not make an electronic candle that will simulate real? After all, thiscandle will work as long as you want, until you “sit” battery. Ask such a purpose, the author has developed an electronic candle on the popular microcontroller ATtiny13V. Included is such a candle in an unusual way. It is worth it just to blow like a candle ignited and begins to reproduce the effect of the light of burning flame. If you blow again, the candle goes out. Thus, organized on-off electronic candles. In order to save battery life after approximately 10 minutes of the candle turns off automatically. To re-enable it, you need to blow on it again. The scheme provided for the control voltage and decrease below the level of the candle goes into alarm. The whole structure is compact enough and. located in Corpus cup from under present candles.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
