Here are a couple of useful resources for learning about programming and electronics using the Arduino board:
- A pretty detailed electronics primer using the Arduino from a very cool woman called Limor Fried: http://www.ladyada.net/learn/arduino/index.html
- The Arduino Programming Notebook by Brian W Evans:
This is an excellent primer on the Arduino’s programming language but also contains very simple circuits so you can get your code to do something in the real world.
Today I managed to control the brightness of an LED with a flex sensor.
