/* 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 Created 26 Sept. 2005 by Tom Igoe modified 24 Apr 2012 by Tom Igoe and Scott Fitzgerald This example code is in the public domain. http://www.arduino.cc/en/Tutorial/SerialCallResponseASCII */ int firstSensor = 0; // first analog sensor int secondSensor = 0; // second analog sensor int thirdSensor = 0; // digital sensor int inByte = 0; // incoming serial byte void setup() { // start serial port at 9600 bps and wait for port to open: Serial.begin(9600); while (!Serial) { ; // wait for serial port to connect.
