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.
