The four programs are:

1. Button 1 turns on and off the LEDs.
2. Count up clock on the 4 digit 7 segment display.
3. Fade the RGB LED.
4. Display the ambient light level on the 4 digit 7 segment display.

To exit out of any of the programs, simply tap Button 2 and you will be taken back to the input.

Working on this project taught me several things including:

• Shift registers and how they work
• Bounce issues with inputs and how to fix that
• What the different pins on an Arduino Uno are capable of
• Static variables
• Volatile variables
• Libraries
• And a few other things that I’m forgetting!

If you would like to look at my wild spaghetti code or the Fritzing files, it’s all available on a GitHub repository.
