MINIMALIST LED LIGHT DETECTING candle

Our flickering LED circuit integrated two understood circuit, as well as definitely wasn’t graceful since of it. [sprite_tm] saw rather a few areas where the circuit might be reduced. He ended up taking it down to just two LEDs, a battery, as well as an ATtiny13. The very first step was getting rid of the present limiting resistors. The datasheet shows that with a 3V supply the AVR will limit the present well below the maximum current. The light sensor was eliminated next. [sprite_tm] referenced an earlier publish on sensing with LEDs. He measures the voltage across one of the LEDs while it is off to see exactly how much light is hitting it. The present draw while on is 10mA as well as 50uA while off.
