What minimum required for start playing Arduino?
The following is a list of items that must be held to start the arduino:
- Arduino board
- USB cable
- Notebook / PC
That's it for a start, if you want to add other components can provide some LEDs and switches.
You can start with the example code contained in Arduino software, begin from Blink, Fade, Button, and so on. Very fun when trying to change the sample code. Once satisfied with the sample code you can create by combining examples. Example code can also be obtained at http://arduino.cc/en/Tutorial/HomePage .
A lot of the forums that discuss Arduino, making it easier to learn, most of them are very happy to share.
