Add a potentiometer to your breadboard project tnat won't fall out, thanks to two 3-pin headers on each side. Plus, it's extremely small so it won't waste breadboard space. The eeZee Potentiometer comes in values of 1k, 10k, and 100k ohms. The big knob is easy to turn by hand or with a small screwdriver.
The pinout is intuitive. The potentiometer has a middle-pin wiper, and two pins for each side of the resistor. Likewise, on each side of the board, the middle pin is the wiper, the other two pins are each end of the resistor.
Solder on the pin headers by first installing them in your breadboard, then placing the board over the headers. Now, solder one pin of one side. Then solder one pin of the other side. Solder the remaining pins. Be sure to use rosin core solder and, ideally, flux pen or flux paste. Clean up the mess with toothbrush and 99% rubbing alcohol. And that's it. You're ready to go.
