Arduino recently unveiled the Arduino Due, a board with a 32-bit Cortex-M3 ARM processor that offers more computing power for makers with complex projects such as FM radios, 3-D printer kits, or drones.

Google has also released an Arduino-based developer board that lets an Android phone interact with motors, sensors, and other devices. This permits building Android apps that use the phone’s camera, motion sensors, touch screen, and Internet connectivity to control a display or a robot.

Arduino is a low-cost microcontroller board that can be connected to all kinds of sensors, lights, motors, and other devices, with easy-to-learn programming software. Arduino has spawned an international do-it-yourself revolution in electronics. More than 250,000 Arduino boards have been sold around the world. You can buy an Arduino board for just about US $30 or build your own from scratch: All hardware schematics and source code are available for free under public licenses. As a result, Arduino has become the most influential open-source hardware movement of its time.
