These are our favorite trim pots, perfect for breadboarding and prototyping. They have a long grippy adjustment knob and with 0.1" spacing, they plug into breadboards or perfboards with ease. This is the same pot that comes with our character LCDs and tutorial packs.

This potentiometer is a two-in-one, good in a breadboard or with a panel. It's a fairly standard linear taper 10K ohm potentiometer, with a grippy shaft. It's smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are 0.2" apart with pin-points, so you can plug it into a breadboard or perfboard. Once you're done prototyping, you can drill a hole into your project box and mount...

As any engineer will tell you, 0.1uF ceramic capacitors are the magic fairy dust of electronics - sprinkle them over your circuit schematics for good luck! But seriously, a 0.1uF capacitor right next to the VCC pin of your chips will improve stability by filtering out power supply spikes and noise that can cause flaky behavior. We love these little guys, they have 0.1" spacing so fit into any perf or breadboard, compact and good quality. We...

This Big Freaking Capacitor is just the trick when you have a lot of current sloshing around your project. They'll help smooth out voltage spikes by providing a little buffering. We use these to help stabilize solar panels on our solar Lipoly charger kit, but they'd also be great with our servo driver boards or on the power connection to our 5V 10A power supply 4700uF capacitance for up to 10V power supplies. 4700uF 10v Electrolytic...

When I was studying power supply electronics in school, the instructor always talked about adding BFC's to the circuit - Big Freakin' Capacitors. This here is UHFC - Unbelievably Huge Freaking Capacitor. If you have a super-cap project that needs up to 700  Farads of capacitance, check it out. Like most super-caps it has a 2.5V-max rated voltage, and remember that unlike a voltage-output battery the voltage drops immediately as it...

This 1K potentiometer is a two-in-one, good in a breadboard or with a panel. Its a fairly standard linear taper 1K ohm potentiometer, with a grippy shaft. Its smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are 0.2" apart with pin-points, so you can plug it into a breadboard or perfboard.

We like capacitors so much we made a kids show about them.   They're super handy and it's really helpful to have a variety lying around to pick and choose from. This is a 10 pack of  10uF 50v  capacitors, so they can be used with any DC voltage up to 50V.  They have a tolerance of ±20% and long flexible pins that make them great for perf or breadboards. Remember that electrolytic capacitors are...

It's half USB Key, half Adafruit Trinket, half mini slide pot ...  it's  Slider Trinkey , the circuit board with a Trinket M0 heart, NeoPixel glow, and a 35mm long 10KΩ slide potentiometer.  The PCB is designed to slip into any USB A port on a computer or laptop. There's an ATSAMD21 microcontroller on board with just enough circuitry to keep it happy. One pin of the microcontroller connects to the middle of...

Oh say can you see By the knob's early light... Sorry - we thought that was clever.  And while it wasn't really, this potentiometer definitely is! We've seen these in miniature synthesizers. They're bigger than a trim-pot, but smaller than a chunky potentiometer. Best of all no knob required! These have a knurled plastic grip with a white stripe marking. Use it as-is, for a low cost adjustment Comes as a standard 10K ohm...

Slip slidin' away  Slip slidin' away  You know the nearer your resistance  The more you're slip slidin' away 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 so cute and short at only 35mm. Use as a voltage divider, and you can visually gauge the voltage...

This Panel Mount Right Angle 10K Linear Potentiometer w/ On-Off Switch is a two-in-one, with both a breadboard-friendly potentiometer and a switch. For the potentiometer-half, you've got a standard linear taper 10K ohm potentiometer, with a grippy shaft. It's smooth and easy to turn, but not so loose that it will shift on its own. It also comes equipped with an on/off switch at the beginning of the shaft's rotation. We like this one...

This potentiometer is a two-in-one: it's a log taper 10K ohm potentiometer , with a grippy shaft an d it comes with an on-off switch . It's smooth and easy to turn, but not so loose that it will shift on its own. We like this one because the legs are 0.2" apart with pin-points, so you can plug it into a perfboard. Note the spacing on the switch/pot pins is 0.2" so it wont work in a solderless breadboard as nicely, unless you...

For the easiest way possible to measure twists, turn to this STEMMA potentiometer breakout (ha!). This plug-n-play pot comes with a JST-PH 2mm connector and a matching  JST PH 3-Pin to Male Header Cables - 200mm, so wiring up is a cinch. Simply plug the cable in, then use the black wire to connect to your ground, white wire to the input/signal pin and the red wire to your power pin. The power pin voltage should match the voltage max of your...

We've had a foot pedal switch in the store for a while but some people have contacted us asking if there was a way to retrofit it to perform variable speed control, like a potentiometer. And here it is! This is a Foot Pedal Potentiometer (a.k.a Sewing Machine Speed Controller). This is a really nice quality one, very sturdy, with a friendly 3.5mm 'audio' connector on the end, so it's incredibly easy to integrate into your...

This Panel Mount 10K Dual Log Potentiometer is a dual-ganged potentiometer that will satisfy all your stereo-signal needs. Instead of just one potentiometer, you actually get two separate pots, 'ganged' together. Turning the grippy shaft twists both standard logarithmic-taper 10Kohm potentiometers. It's smooth and easy to turn, but not so loose that it will shift on its own. We also offer this potentiometer in a singular...
