WIP - concentric rings generated by heartbeats

Dependencies

• NodeJS
• P5.serialserver
• Local server

Use

1. Connect PulseSensor to Arduino (Red - 5V, Black - GND, Purple - A0).
2. Run a server using the companion library p5.serialserver: navigate to p5_serialserver folder on Terminal and start a server using the command node startserver.js. More at https://github.com/p5-serial/p5.serialserver.
3. Upload Arduino code at Arduino/pulseSensorServer.ino to write outputs on the serial port.
4. Go live here! Using VSCode Live Server extension is the easiest way, node should work too.

Other

• Arduino port is set to "/dev/tty.usbmodem101". Change if needed.
• Heartrate values generally around 100-120.

To-Do

• Make rings last longer
• Change texture of rings based on other parameters
• Add patterns to the edge of the rings
• Make background more aesthetically pleasing
• Alter threshold to account for general peak heartrate values
• Adapt for touch screen(?)
• Sound
• Disappear when touched but save to show at end
• Show actual p mirabilis images before disappearing or a tree ring etc.
• Replay rings that are currently frozen
