“Arduino is a single-board microcontroller designed to make the process of using electronics in multidisciplinary projects more accessible. The hardware consists of a simple open source hardware board designed around an 8-bit Atmel AVR microcontroller, though a new model has been designed around a 32-bit Atmel ARM. The software consists of a standard programming language compiler and a boot loader that executes on themicrocontroller.
Arduino boards can be purchased pre-assembled or do-it-yourself kits. Hardware design information is available for those who would like to assemble an Arduino by hand. It was estimated in mid 2011 that over 300,000 official Arduinos had been commercially produced at that point.“
I think everybody can use arduino. It’s very easy to start without any before experience of using arduino or programming.
