  • Big, Auto Dim, Room Clock (using Arduino and WS2811)

    I made three of these clocks years ago. I now added a brightness dimmer that is dimming the leds as the light gets lower and brighting the leds as the light gets higher. You'll need an LDR and a resistor. Google 'LDR and Arduino' and you'll get lots of hits on how to wire it. I use A0 pin.// Check Light sensor and set brightness accordinglyvoid BrightnessCheck(){ const byte sensorPin = 0; // Analog light sensor pin int sensorValue = analogRead(sensorPin); // Read sensor sensorValue = 1023 - sensorValue; //LED gets brighter the darker it is at the sensor that means we have to -invert- the reading from 0-1023 back to 1023-0 const byte LEDbrightness = map(sensorValue, 0, 1023, 20, 255); LEDS.setBrightness(LEDbrightness); };Just replace the above code with your void Brightness…

    Actually it's called initialism. It's the abbreviation made out of the initials. :)
