If you're tired of the regular-old-twisty potentiometers we carry, why not slide over and try this slide pot? Most famously used on mixers and the transporter control panel on Star Trek, these slide pots are not too long at only 45mm. Use as a voltage divider and you can visually gauge the voltage from low to high. There's a center indentation so you know when you're in the middle. Best of all, it comes with a knob (e.g. nubbin)!
Comes as a standard 10K ohm linear potentiometer, and it works great for breadboarding and prototyping. You can solder to the 3 legs or sorta push it into a solderless breadboard (or a perfboard with large holes).
It has a nice feel, sliding it back and forth is quite satisfying.
Jargon buster
Plain-language definitions for the technical terms used above.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
- solderless breadboard
- A reusable board with rows of internally connected holes for building circuits by pushing in components and jumper wires, with no soldering required. It lets you prototype and rewire a circuit quickly and reversibly before committing to a permanent, soldered build.
