ARDUINO WORKSHOP
A bit of history
- 2001 : turning point
- Processing is born @ mit
- Before 2005, we had basic stamp
- It was enough for quite a few projects but had many limitations
History
- It costs around 100$
- Reinterprets basic program each time it runs
- Low memory
- Closed hardware
- Couldn’t run on mac
What is arduino...
ARDUINO IS AN OPEN-SOURCE ELECTRONICS PROTOTYPING PLATFORM BASED ON FLEXIBLE, EASY-TO-USE HARDWARE AND SOFTWARE. IT'S INTENDED FOR ARTISTS, DESIGNERS, HOBBYISTS AND ANYONE INTERESTED IN CREATING INTERACTIVE OBJECTS OR ENVIRONMENTS.
Why arduino...
- Open source hardware and software
- Easy prototyping
- Economical
- Compatible with mac
- And…..lots of examples!!!
Arduino comes in many shapes and sizes
arduino uno
analog vs digital
digital signal
- it is discrete
- it is either 0 or 1
- e.g. switches, triggers
analog signal
- it is a continous signal
- its value ranges from 0 - 256
- e.g. audio signal, temperature

electronics part
- 8 bit AVR micro-controller
- Boot loader
- Usb controller
- External power jack
analog input pins
digital input pins
AVR microcontroller
Typically :
- They use less power than a normal comp.
- Are small and can be battery operated
- Programmed to do specific tasks
- Read voltages
- Generate signals
