ACTIVITY #4: PUSHBUTTON, LED, AND SPEAKER
The LED and speaker can be used as status indicators. Primarily, the beeping and LED
blinking helps you know when the SumoBot is doing its 5 second countdown. These
indicators are also useful for trouble-shooting SumoBot behavior problems. The single
pushbutton can be used along with the indicators to adjust the SumoBot's behavior
between sumo rounds and even select between different operation modes.
