Beat Playground

A rhythm game for the Adafruit Circuit Playground Express.

Setup

1. Install the Arduino SAMD board profile and the Adafruit Circuit Playground and AsyncDelay libraries using the Arduino IDE or CLI

arduino-cli core install arduino:samd
arduino-cli lib install 'Adafruit Circuit Playground'
arduino-cli lib install AsyncDelay

2. Compile and upload Beat Playground to your Circuit Playground Express using the Arduino IDE or CLI

arduino-cli compile beat-playground --fqbn arduino:samd:adafruit_circuitplayground_m0
arduino-cli upload beat-playground --port /dev/ttyACM0

Game Instructions

1. Use the left and right buttons to select a song (see list of songs below). The current selected song number will be displayed on the NeoPixels
2. "Tap" the air with the board (as if you're hitting a drum) to start the song
3. Tap along with the melody. Green lights indicate a correct tap and red lights indicate an incorrect (out of time) tap
4. When the song ends, your score (1-10) will be displayed on the NeoPixels
5. Tap or press either button to return to the song selection menu

Songs Included

1. Twinkle Twinkle Little Star
2. Centuries (Fall Out Boy)
3. Blinding Lights (The Weeknd)
4. Counting Stars (OneRepublic)

Important Constants

Declared at the top of beat-playground/beat-playground.ino

Name	Default	Description
ACCELERATION_THRESHOLD	20	The minimum net acceleration for a tap to be registered (in m/s^2). Update to adjust the sensitivity of the tap detector.
TIMING_THRESHOLD	100	The maximum offset of a correct tap (in ms). Update to adjust the difficulty.
SENSOR_REFRESH_PERIOD	50	How often the program tries to detect a tap (in ms). This should be less than TIMING_THRESHOLD.
