/* Reading a serial ASCII-encoded string.

This sketch demonstrates the Serial parseInt function. It looks for an ASCII string of comma-separated values. It parses them into ints, and uses those to fade an RGB LED.

Circuit: Common-Cathode RGB LED wired like so: * Red anode: digital pin 3 * Green anode: digital pin 5 * Blue anode: digital pin 6 */

// pins for the LEDs: const int redPin = 3; const int greenPin = 5; const int bluePin = 6; void setup { // initialize serial: Serial.begin(9600); // make the pins outputs: pinMode(redPin, OUTPUT); pinMode(greenPin, OUTPUT); pinMode(bluePin, OUTPUT); }

void loop { while (Serial.available > 0) { // look for the next valid integer in the incoming serial stream: int red = Serial.parseInt; // do it again: int green = Serial.parseInt; // do it again: int blue = Serial.parseInt;

// look for the newline. That's the end of your sentence: if (Serial.read == '\n') { // constrain the values to 0 - 255 and invert // if you're using a common-cathode LED, just use "constrain(color, 0, 255);" red = constrain(red, 0, 255); green = constrain(green, 0, 255); blue = constrain(blue, 0, 255);

// fade the red, green, and blue legs of the LED: analogWrite(redPin, red); analogWrite(greenPin, green); analogWrite(bluePin, blue);

// print the three numbers in one string as hexadecimal: Serial.print(red, HEX); Serial.print(green, HEX); Serial.println(blue, HEX); } } }
