"""
|
|
This example uses the Open Trivia Database API to display multiple choice trivia questions.
|
|
Tap the screen to start, then a question will appear and a 30 second timer will start.
|
|
The first player to hit their button will get 10 seconds to answer.
|
|
Hit button again to reveal answer. Tap screen to move to next question.
|
|
This program assumes two buttons are attached to D3 and D4 on the Adafruit PyPortal.
