This example example uses the Arduino board to receive data from the computer. The board turns on an LED when it receives the character 'H', and turns off the LED when it receives the character 'L'.
The data can be sent from the Arduino Software (IDE) serial monitor, or another program like Processing (see code below), Flash (via a serial-net proxy), PD, or Max/MSP.
Step 1: What You Need?

Don't have components? Don't worry. Just click the component's name.
Step 2: Build Your Circuit.
Many Arduino boards have a built-in LED connected to pin 13; if your board has no built-in LED, attach an external LED to pin 13. The long leg, or anode, goes to pin 13 through a 220 resistor. The short leg, or cathode, goes to ground.
Step 3: Upload The Code.
1. Select the Arduino board type: Select Tools >> Board >> Select your correct Arduino board used.
2. Find the port number by accessing device manager on Windows. See the section Port (COM&LPT) and look for an open port named "Arduino Uno (COMxx)". If you are using a different board, you will find a name accordingly. What matters is the xx in COMxx part. In my case, it's COM3. So my port number is 3.
Select the right port: Tools >> Port >> Select the port number.
3. You can find this code in the example of Arduino IDE.
Select File >> Examples >> 04.Communication >> PhysicalPixel
Select File >> Examples >> 04.Communication >> PhysicalPixel
Click press the "upload" button (see the button with right arrow mark).
Processing Code
Copy the Processing code from the code sample above. As you mouse over the center square, the LED on pin 13 should turn on and off. The Processing applet looks like this:
Mouse over the square to turn the LED on and off.
Max patch
The Max/MSP patch looks like the image below. Copy it from the code sample above and paste it into a new patch window.
