Step 4Buttons
Buttons, buttons, everywhere.
The ubiquitous 6mm tactile switch is another breadboard staple. When you need only 1 or 2, you can just stick them in the breadboard. But try using more than that, and you'll soon have buttons popping out by themselves all over the place, in addition to growing a nice plate of spaghetti.
The simple tactile switch's most common role is to provide a digital input by temporarily connecting an input pin to either the ground rail or the power rail. By making a button array, you can plug the ground/power rail in just once, and will also have a greater density of buttons that won't fall out. You can make your button array up to 3 buttons deep and still take up the same number of breadboard holes... but I find 2 rows to be a more convenient size.
