p5.js

• LeapMotion API doc: https://docs.ultraleap.com/api-reference/unity-api/class/class_leap_1_1_hand.html?highlight=hand direction
• leap motion finger detection demo: https://editor.p5js.org/zqyoiv/sketches/guBtRbSQ4
• next step:
  • understand hand.direction() [x ,y, z] array and make the right judgement.
  • think about the layout of the installation.

Arduino

• successfully make serial communication to instruct which LED will light up depends on p5.js output
• Learning: how to debug serial communication:
  • code arduino, open serial monitor, send msg to make sure arduino side is correct
  • close serial monitor
  • code p5, see hardware reaction.
  • Note: the long side of LED is positive
