Quick Draw Duo
- Add some winning and losing sounds.
- Use the accelerometer to change the game to one with a physical draw.
- Find some other uses for a pair of synchronised CPB, e.g. light shows, stereo/spatial audio playback.
- Technical challenge 1: increase the robustness of the communication, e.g. make it recover from transient connectivity issues; match request and response with a suitable identifier.
- Technical challenge 2: understand and set the connection interval for Blutetooth LE GATT transactions and factor this into the design of the board syncronisation process.
- Add a cheat detector to the reaction timer to highlight impossible times and early presses.
- Use the NeoPixels to show the reaction time graphically.
- Increase the complexity of the visual (e.g. different colours, odd vs even) and auditory (e.g. different pitches) stimuli to investigate the additional delays from discrimination.
- Investigate tactile reaction time with some sort of actuator controlled by the CPX/CPB board.
- Examine any effect of using peripheral vision and lower brightness settings on reaction time.
- Add an announcement of each time or the fastest time using sound samples for each digit.
- Independently verify the reaction timing - many smartphones offer high fps video recording in the form of a slow motion mode.
- Circuit Playground Quick Draw - the original project that this one is based on.
- Color Remote with Circuit Playground Bluefruit and Circuit Playground Bluefruit NeoPixel Animation and Color Remote Control - two other projects showing Bluetooth communication between two CPB boards.
