Arduino


Arduino is an awesome tool for physical computing -- it's an open source microcontroller board, plus a free software development environment. Use it to make cool interactive objects that can sense inputs from switches, sensors, and computers, and then control motors, lights, and other physical outputs in the real world!

We've got the latest Arduino boards, clones and mini boards, accessory "shields," starter kits, and more. Check out our Arduino 101 videos and Arduino projects on the MAKE website, then get started!

This is the new Arduino Revision 3! It sports an updated USB controller chip (was an atmega8u, now an atmega16u), duplicated Analog 4 and 5 pins next to the AREF pin (for future shields) and an IOREF pin next to the reset button (to let shields know the I/O voltage of the pins.)

Also, the reset button has moved next to the USB jack to allow for easy access when the shield a shield is on top.

Everything else is the same, processor, driver, board size, upload speed, etc, so it is compatible with all current shields and code.
