4. What is Arduino ®
Arduino ® is an open-source prototyping platform based in easy-to-use hardware and software. Arduino ® boards
are able to read inputs – light-on sensor, a finger on a button or a Twitter message – and turn it into an output –
activating of a motor, turning on an LED, publishing something online. You can tell your board what to do by
sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming
language (based on Wiring) and the Arduino
® software IDE (based on Processing).

5. Overview
Most Arduino ® boards have limited onboard memory storage. The SD card logging shield allows expanding the
storage to up to 2 GB.
If you have a project with any audio, video, graphics, data logging, etc. in it, you will find that having a
removable storage option is essential. Most microcontrollers have extremely limited built-in storage. For
example, even the Arduino
® ATmega2560 has a mere 4k bytes of EEPROM storage. There is more flash (256k)
but you cannot write to it as easily and you have to be careful if you want to store information in flash that
you do not overwrite the programme itself!
