[TheDarkestNight]

Well I've been interested in Arduino for a while and I started searching and found alot of Arduino Shields, what is an Arduino Shield?

[Spyman]

The Arduino is a small microcontroller and the "shield" is a complementary circuit board adapting its functionality to different usages.

 

An Arduino board consists of an 8-bit Atmel AVR microcontroller with complementary components to facilitate programming and incorporation into other circuits. An important aspect of the Arduino is the standard way that connectors are exposed, allowing the CPU board to be connected to a variety of interchangeable add-on modules (known as shields).
