Communication examples include code that allows the Arduino to talk to Processing sketches running on the computer. For more information or to download Processing, see processing.org. There are also Max/MSP patches that can communicate with each Arduino sketch as well.

• Dimmer - Control Brightness of LED with mouse on PC
• Graph: Send data to the computer and graph it in Processing.
• MIDI Note Player
• Physical Pixel: Turn a LED on and off by sending data to your Arduino from Processing
• Serial Call and Response (handshaking)
• Virtual Color Mixer

The following tutorials show how to use various control structures within the C programming language that is in the Arduino IDE.

• Arrays: A variation on the For Loop example that demonstrates how to use an array.
• For Loop Iteration (aka The Knight Rider)
• If Statement Conditional: Use an ‘if statement’ to change the output conditions based on changing the input conditions.
• Switch Case How to choose between a discrete number of values.
• Switch Case 2: A second switch-case example, showing how to take different actions based on the characters received in the serial port.
• While Statement Conditional: How to use a while loop to calibrate a sensor while a button is being read.

Some Mini Projects

• 7 Seg Display and 3x4 Matrix Keypad
