Serial Call and Response in ASCII
|
|
Language: Wiring/Arduino
|
|
|
|
This program sends an ASCII A (byte of value 65) on startup
|
|
and repeats that until it gets some data in.
|
|
Then it waits for a byte in the serial port, and
|
|
sends three ASCII-encoded, comma-separated sensor values,
|
|
truncated by a linefeed and carriage return,
|
|
whenever it gets a byte in.
|
|
|
|
Thanks to Greg Shakar and Scott Fitzgerald for the improvements
|
|
|
|
The circuit:
|
|
* potentiometers attached to analog inputs 0 and 1
|
|
* pushbutton attached to digital I/O 2
