I have a few bread boards, microcontrollers, resistors, LEDs and so on—the stuff I obviously need to get anything done. But I'd like to step up my prototyping game, and when it comes to choosing switches, buttons, connectors and other handy doodads, there's such an overwhelming array of options to choose from it's hard to know where to start.
What have you found to be useful in your prototyping toolbox?
