No, I'm not connected with AdaFruit.... but I like them very much. • https://www.adafruit.com/ • https://learn.adafruit.com/adafruit-n... • The software brightness control added to the strandtest demo works like this: • // Connect a potentiometer between the Arduino +5v and Ground, • // wiper to Analog Input potPin declared below. • // • // At the top of the sketch before setup put: • #define potPin A0 • int MaxBright = 127; //sets initial brightness to half • // then in each display function in the strandtest sketch, • // before each strip.show() statement, put: • MaxBright = map (analogRead(potPin), 0,1023,0,255); • strip.setBrightness(MaxBright); • // and now the potentiometer will control the strip brightness.
