Once the color sequence is complete, the program will loop back to the beginning and repeat the sequence. For each of these colors, we'll turn the necessary RGB LEDs on or off.Īfter uploading your code, the RGB LED will step through a color sequence beginning with all LEDs off ('black'), red, yellow, green, cyan, blue, magenta, and white. Keep this in mind as you prototype with the LED and mix your colors. turn on the LEDs you will set them LOW instead of HIGH. Note: for this particular LED, the wiring shares a common anode (+), which means to This code will step through the six primary and secondary colors, plus white and black.
