The boards feature serial communications interfaces, including [[Universal Serial Bus]] (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the [[C (programming language)|C]] and [[C++]] [[programming language]]s (Embedded C), using a standard API which is also known as the '''Arduino Programming Language''', inspired by the [[Processing (programming language)|Processing language]] and used with a modified version of the Processing IDE.

At that time, the students used a [[BASIC Stamp]] [[microcontroller]] at a cost of $50. In 2004, [[Hernando Barragán]] created the development platform ''[[Wiring (development platform)|Wiring]]'' as a Master's thesis project at IDII, under the supervision of Massimo Banzi and [[Casey Reas]]. Casey Reas is known for co-creating, with Ben Fry, the [[Processing (programming language)|Processing]] development platform.

This was revealed when the Arduino company tried to register the trademark in other areas of the world (they originally registered only in the US), and discovered that it was already registered in Italy. Negotiations with Martino and his firm to bring the trademark under the control of the original Arduino company failed. In 2014, Smart Projects began refusing to pay royalties. They then appointed a new CEO, Federico Musto, who renamed the company ''Arduino SRL'' and created the website ''arduino.org'', copying the graphics and layout of the original ''arduino.cc''.

Some serial Arduino boards contain a level shifter circuit to convert between [[RS-232]] logic levels and [[transistor–transistor logic]] ([[TTL serial]]) level signals. Current Arduino boards are programmed via [[Universal Serial Bus]] (USB), implemented using USB-to-serial adapter chips such as the [[FTDI]] FT232.

Other variants, such as the Arduino Mini and the unofficial Boarduino, use a detachable USB-to-serial adapter board or cable, [[Bluetooth]] or other methods.
