/*
Debounce
Each time the input pin goes from LOW to HIGH (e.g. because of a push-button
press), the output pin is toggled from LOW to HIGH or HIGH to LOW. There's
a minimum delay between toggles to debounce the circuit (i.e. to ignore
noise).
The circuit:
* LED attached from pin 13 to ground
* pushbutton attached from pin 2 to +5V
* 10K resistor attached from pin 2 to ground
* Note: On most Arduino boards, there is already an LED on the board
connected to pin 13, so you don't need any extra components for this example.

/*
State change detection (edge detection)
Often, you don't need to know the state of a digital input all the time,
but you just need to know when the input changes from one state to another.
For example, you want to know when a button goes from OFF to ON. This is called
state change detection, or edge detection.
This example shows how to detect when a button or button changes from off to on
and on to off.
The circuit:
* pushbutton attached to pin 2 from +5V
* 10K resistor attached to pin 2 from ground
* LED attached from pin 13 to ground (or use the built-in LED on

/*
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 is attached to analog in pin 0.

/*
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

Arrays
Demonstrates the use of an array to hold pin numbers
in order to iterate over the pins in a sequence.
Lights multiple LEDs in sequence, then in reverse.
Unlike the For Loop tutorial, where the pins have to be
contiguous, here the pins can be in any random order.
The circuit:
* LEDs from pins 2 through 7 to ground

Conditionals - If statement
This example demonstrates the use of if() statements.
It reads the state of a potentiometer (an analog input) and turns on an LED

The circuit:
* potentiometer connected to analog pin 0.

side pins of the potentiometer go to +5V and ground
* LED connected from digital pin 13 to ground
* Note: On most Arduino boards, there is already an LED on the board
connected to pin 13, so you don't need any extra components for this example.
