This is incredibly useful when working on an Arduino project. The Arduino Uno board comes equipped with a convenient nut holder located at the back of the board, which can securely hold 3mm nuts in place. Additionally, this versatile board features a standard breadboard area where you can connect and test your circuit components. It also has ample space for anything else you might need to incorporate into your project. This makes it ideal for situations when you're not yet finished with your project and want to put it aside temporarily.
