Brick-Big LED

Brick Big LED

This creates a Processing Sketch on the PC that displays a big colorful "LED" on the screen that follows the pin 13 LED on an Arduino.

PROCESSING SKETCH (Copy / paste into New Processing IDE window).

You need to install the free "Processing" IDE on your computer. See: https://processing.org/download/ You will see that it looks almost like Arduino! That's because Arduino was based on Processing. Copy and paste the Processing sketch below into the Processing IDE and run it.
  Make sure you edit this sketch to put in the COM port your Arduino is using!
