serial communication - a communication protocol between computers, 1 byte at a time

uploading Arduino code requires you to use serial port and usb, so you can’t use p5 at the same time. in 0101010 format the voltage goes up and down to send the signal.

9600 - we can change how fast it reads/writes too, but 9600 is default

serial.write() - NO ASCII CONVERSION

• print(255) send 3 pieces of information
• write(255) sends 1 piece of information
