Homework
1) Find a good diffuser for your RGB LEDs (e.g. ping pong ball, Styrofoam, etc).
2) Change the code so that you can control the RGB values with multiple key presses. For example, pressing ‘r’ 5 times will set the brightness to 50% (or brightness = 127) and pressing ‘r’ 10 times will set it to 100% (or brightness = 255).
3) (Optional) Come up with other ways of controlling the colors of the LEDs using the keyboard. Here’s your chance to be creative. You can show off to your friends next week. Example: Read colors and set the appropriate RGB values like “orange” might set r=70%, g=50%, and b=0%.
Lab instructions will be passed out during lab and also available as a pdf attached to this page.
