These are our favorite trimpots, 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...

Nothing makes a project harder to maintain than a lot of loose wiring. That's why we like to use terminal blocks whenever making PCB-to-Wire connections. These particular 3.5mm terminal blocks are...

After a long day out harvesting in the terminal block fields, we've returned with a veritable bounty of these very nice and compact 2.54mm/0.1" terminal blocks in a variety of sizes. Our harvest of...

This potentiometer is a two-in-one, good in a breadboard or with a panel. Its a fairly standard linear taper 10K ohm potentiometer, with a grippy shaft. Its smooth and easy to turn, but not so loose...

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 knob definitely is.  It's a 'soft touch' T18 knob that...

Connect this to that without soldering using these handy mini alligator clip test leads. 15" cables with alligator clip on each end, color coded. You get 12 pieces in 6 colors. Strong and grippy,...

Simple but effective - this breakout board has a USB Micro-B connector, with all 5 pins broken out. Great for pairing with a microcontroller with USB support, or adding USB 5V power to a project. We...

Little clicky switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solderless breadboard. The pins are normally open (disconnected) and when the...

These Simple RF receivers are the easiest way possible to add wireless control, painlessly! There's no programming, configuring or addressing - simply power the receiver with 5-10VDC and press the...

This 4-button keyfob remote goes with Adafruit's basic 315MHz RF receiver modules. It will work with all of them, sending out one of four commands that match up with the four outputs. Its small and...

The "poor man's" accelerometer/motion sensor! These spring-vibration switches are high sensitivity non-directional vibration induced trigger switches. Inside is a very soft spring coiled around a...

Make your own little LED strip arrangement with this stick of NeoPixel LEDs. Adafruit crammed 8 of the tiny 5050 (5mm x 5mm) smart RGB LEDs onto a PCB with mounting holes and a chainable design. Use...

This is hot! Literally! Apply 5-12VDC and the stainless steel fibers in this heating fabric will warm up, creating a little heating pad. On one hand, it's just a gigantic resistor. On the other hand,...

Transistors are powerful little electronic switches, and we really like these NPN transistors whenever we need to control medium-power electronics such as small motors, solenoids, or IR LEDs. We find...

Listen up! This 1.1" (~30mm) diameter speaker is the perfect addition to any breadboard-based audio project where you need 8 Ohm impedance, and have 0.2W or less of power. The two pins are 15mm / 0...

These nice switches are perfect for use with breadboard and perfboard projects. They have 0.1" spacing and snap in nicely into a solderless breadboard. They're easy to switch no matter what size...

Move fluid safely from here to there with this very nice little pump. Unlike most liquid pumps, this is a peristaltic type - the pump squishes the silicone tubing that contains the liquid instead of...

Bring a little bit of Times Square into your home with this 16 x 32 RGB LED matrix panel. These panels are normally used to make video walls, but in New York you can see them on the sides of busses...

Little clicky switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solderless breadboard as shown in this tutorial. The pins are normally open...

The Raspberry Pi B+ / Pi 2 / Pi 3 / Pi 4 has landed on the Maker World like a 40-GPIO pinned, quad-USB ported, credit card sized bomb of DIY joy. And while you can use most of our great Model B...
