SKU: ETR101 Category:


The Arduino UNO R3 is an open-source microcontroller board based on the Microchip ATmega328P microcontroller. This development board is equipped with sets of digital and analog input/output (I/O) pins that can be interfaced with various expansion boards (shields) and other circuits. The board has 14 Digital pins, 6 Analog pins, and programmable with the Arduino IDE (Integrated Development Environment) via a type B USB cable. It can be powered by the USB cable or by an external 9-volt battery, though it accepts voltages between 7 and 20 volts.

Arduino Uno R3 boards are able to read inputs – light on a sensor, a finger on a button, or a Twitter message – and turn it into an output – activating 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.

Arduino Uno R3 can be used to develop stand-alone interactive objects or can be connected to software on your computer. The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).
