| 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 attached to analog in pin 0 | |
