/*
Console Pixel
An example of using the Arduino board to receive data from the
Console on the Arduino Yun. In this case, the Arduino boards turns on an LED when
it receives the character 'H', and turns off the LED when it
receives the character 'L'.
To see the Console, pick your Yun's name and IP address in the Port menu
then open the Port Monitor. You can also see it by opening a terminal window
and typing
ssh root@ yourYunsName.local 'telnet localhost 6571'
then pressing enter. When prompted for the password, enter it.
The circuit:

#include <Console.h>
const int ledPin = 13; // the pin that the LED is attached to
char incomingByte; // a variable to read incoming Console data into
void setup() {
// initialize Console communication:
Bridge.begin();
Console.begin();
while(!Console); // wait for the Console to open from the remote side
Console.println("type H or L to turn pin 13 on or off");
// initialize the LED pin as an output:
pinMode(ledPin, OUTPUT);
}
void loop() {
// see if there's incoming Console data:
if (Console.available() > 0) {
// read the oldest byte in the Console buffer:
incomingByte = Console.read();
Console.println(incomingByte);
// if it's a capital H (ASCII 72), turn on the LED:
if (incomingByte == 'H') {
digitalWrite(ledPin, HIGH);
}
// if it's an L (ASCII 76) turn off the LED:
if (incomingByte == 'L') {
digitalWrite(ledPin, LOW);
}
}
