We'll outline the basics of the Arduino itself, what the crazy jumble of wires means, and then step through how to use other people's code and schematics to build your first electronics project ...

The Arduino Sketch (code) uses the external interrupt (int 0) on Arduino’s digital pin 2 (D2). This is used to read the output pulses coming from the water flow sensor. When Arduino detects the pulse, ...

The official Arduino IDE is a dour piece of software designed for uploading code to the ubiquitous and super-cool micro controller. It is a standalone, non-networked app that isn’t very pretty ...
