What is an Arduino Shield?

Arduino Shields are expansion modules intended for use with the Arduino board. Since the name “Arduino Shield” is reserved, it can only be used in relation to the original accessories released by the authors of Arduino. Among the shields you will find e.g. controllers for motors and servos, keyboards, displays, sensors, loudspeakers, microphones, measuring devices, communication interfaces, network modules, output expanders and many other expansions. Just like when buying a board, it is always worth checking if it is an original product from Arduino or other good and reliable shield designers (e.g. Adafruit or SparkFun).

With Arduino you can create a virtually unlimited number of projects. The device works perfectly as a driver or controller, so you can use it for intelligent clothing, building automation systems, lighting systems, alarms, security systems, remote controlled vehicles, robots, drones, homemade measuring devices and many other projects. A wide range of projects using different versions of the Arduino board are available on the Forbot technology blog and on YouTube channels for electronics, for example. There are also many describing how the board works and how to use it – one of the most interesting is a series of guides from Simon Monk.
