This demo uses GEX to drive NeoPixels. It is a Python implementation of the Pomodoro timer.

The strip shows:

• a shortening red strip during the work phase
• dim orange/red when the user should start working
• dim green when the break can be started
• and a shortening green strip during the break phase

The end-of-phase wait states are left by pushing a button, entering the following break or work period.
