Getting started with interactive projects

using the Arduino, Max and Processing

What’s a micro-controller?

A Micro-controller is an integrated circuit that contains many of the same items that a desktop computer has, such as CPU, memory, etc., but does not include any “human interface” devices like a monitor, keyboard, or mouse. Micro-controllers are mostly designed for machine control applications, rather than human interaction.

Micro-controllers paired with all the peripherals they need to be self-sufficient, such as the Arduino Board, are sometimes called “single-board computers.”

What is Arduino?

• Open Source Physical Computing Platform• Open source: free to inspect & modify• physical computing platform for all sorts of projects• A physical board, a programming environment, a development philosophy• Tiny computer you can program to do all sorts of tasks• Completely stand-alone, or used to communicate with other devices

What is Arduino?

Arduino is also a standardized “bootloader”• A tiny program that loads other programs• It’s alive during first 5 seconds

After 5 seconds, your program runsDon’t need special programmer board with a bootloader

What is Arduino?

Capabilities• 8 kBytes of Flash program memory• 1 kByte of RAM• 12 MHz (Apple II: 1 MHz)• Inputs and Outputs• 13 digital input/output pins• 5 analog input pins

Digital I/O can read switches and buttons, control LEDs and motorsAnalog input can read knobs or other varying sensorsAnalog output can be done with PWM

• Arduino is very similar to Basic Stamp (if you know it)• but cheaper, faster, & open source• Uses AVR ATmega8 or Atmega168 microcontroller chip Basic Stamp uses PIC microcontroller chip.

PICs and AVRs are very comparable, one’s not necessarily better than the otherAVRs are a little easier if you’re using a language like C (stack-based)Don’t need to worry about the chip particulars for now

“ArduinoDimmer” Simple MAX patch to send data to the arduino

1) Quit Max

2) In the arduino environment open: arduinoSerialreader_wiring.pde

4) start Max

3) Upload to Arduino

5) open Arduino2Max_MaxPatch
