/*
|
||||
Graph
|
||||
|
||||
A simple example of communication from the Arduino board to the computer:
|
||||
the value of analog input 0 is sent out the serial port. We call this "serial"
|
||||
communication because the connection appears to both the Arduino and the
|
||||
computer as a serial port, even though it may actually use
|
||||
a USB cable. Bytes are sent one after another (serially) from the Arduino
|
||||
to the computer.
|
||||
|
||||
You can use the Arduino serial monitor to view the sent data, or it can
|
||||
be read by Processing, PD, Max/MSP, or any other program capable of reading
|
||||
data from a serial port. The Processing code below graphs the data received
|
||||
so you can see the value of the analog input changing over time.
|
||||
|
||||
The circuit:
|
||||
Any analog input sensor is attached to analog in pin 0.
