What is Arduino?

Arduino is an open-source electronics platform based around the Atmel AVR microcontroller family. With a free C++ based development environment, Arduino makes it simple to add sensing and control to a huge range of projects, whether you are an engineer, designer, artist or hobbyist. Here at element14 you can find a fantastic range of Arduino boards, shields, tools and learning resources.

Arduino Uno

Arduino Uno



Based on the ATmega328 microcontroller, the Uno is a popular and versatile board from Arduino. With 14 digital I/O pins (of which 6 provide PWM), 6 analogue inputs and a 16 MHz crystal oscillator, you can simply connect to a computer via USB and start your next project. You will find an Uno at the heart of many projects, even the LHC at CERN has one!

Arduino Leonardo

Arduino Leonardo



The Arduino Leonardo features an ATmega32u4 MCU and comes with 20 digital I/O pins (7 for PWM), micro USB and ICSP header. Unlike the Uno and other preceding boards, the Leonardo makes use of the built-in USB communication in the MCU so can be used for keyboard or mouse emulation.
