About serial communications
some notes:
  · Electrical: what is the voltage of the pulses?
  · Data rate: How often is a bit of data sent?
  · Logic: Does low voltage  mean the bit is a 0 or a 1?

Lab: serial communications
this week is about serial communications. By using serial communication methods link arduino with p5.js, we can physically controlling the web world.
With the lab constructions, I used the potentiometer to control a simple sketch face's movement that drawing in the p5.js webediter.
This lab is about serial input to P5.JS

I went to Art institute of Chicago this weekend, and I want to share the only interactive piece in art institute museum.
