2. What in the world is an Arduino?
• Open Source Electronics Prototyping
Platform
• Just a Microcontroller (eg. ATMega328 in
an Arduino Uno) and other components
fabricated onto a single board allowing
very simple interfacing and
programming!

5. What can I do with it?
• Do Physical Computing!
– sense the physical world (light, temperature,
pressure, etc) and do stuff with the data!
• Build cool mechanical systems driven by code
(like Robots, cars etc.)
• You got the idea!
