This video tutorial introduces and explains three common jargon terms related to Arduino: Arduino shields, Arduino pins, and breakout boards. Arduino shields are additional circuit boards that expand the capabilities of an Arduino board, such as adding GPS functionality. Arduino pins are the metal prongs on a microcontroller used for input and output connections. Breakout boards are small printed circuit boards with specific circuits, like temperature sensors, that connect to Arduino boards but are generally less expensive than shields.

What are the common uses of an Arduino shield in projects?

How do breakout boards connect to an Arduino, and what are their advantages?
