Arduino is an open-source electronics platform consisting of hardware and software. Every aspect is designed to be straightforward so you can learn to code or design a project, quickly and easily. It’s designed for students, programmers, designers, hobbyists and tinkerers.
The Arduino open-source software (IDE) is there to help too. It makes is much easier to write code and transfer it to your board.

Arduino AVR Development Boards

We have a range of Arduino boards at RS that feature an AVR ATmega microcontroller at the core. Most of the boards feature the 32u4 microcontroller with the Mega boards featuring the ATmega 2560 and the Uno/Nano boards featuring the ATmega328 microcontroller. These Arduino boards are designed to be used with Arduino IDE programming software.
