Code is explained in the comment section. With analogWrite s maximum output value of 255, each. 1 Your timing code is correct, but it does the wrong thing every second-it sets the color to red, shows it, and then immediately sets the color to black and shows it. In this example RGB LED is set to different colors, it observes a delay of 1 second between each change. When the effect is not running, the LEDs are to be set 100% brightness. Kinda hard for me to read code in another language, but you might want to declare the time in the first if() at the beginning so you can easily modify the speed of the fade. We are going to explore and implement two different RGB crossfade approaches. One further question I’m now struggling with I want this effect to run 8 times every 15 minutes. When you run them at different brightnesses, the red, green and blue mix to form new colors. Thanks Jammy! That stopped the LED flash I was having at 100% brightness, and changing your second if statement to a value of 155 instead of 255 got me exactly what I was after Arduino - LED - Blink Without Delay Lets imagine that Arduino has to do two tasks: blinking LED and checking the button state, which can be pressed anytime. 317 lines (222 sloc) 8.6 KB Raw Blame / SparkFun Inventor's Kit Example sketch 03 RGB LED Make an RGB LED display a rainbow of colors Hardware connections: An RGB LED is actually three LEDs (red, green, and blue) in one package.
