For projects that need a rotary encoder but need to keep it single-sided or need to avoid interrupting traces or devices on the other side, here...

Back in my day, if you wanted to make a mechanical keyboard, you had to solder in expensive key switches onto your PCB - and woe to the person who ...

This switched JST connector is the best way to quickly prototype with our LiPoly batteries. We paired a genuine JST connector with a slide switc...

This T-Slot Photo Interrupter is a simple plastic sensor with two elements - an IR LED and an IR photo-transistor, situated across a U-shaped ga...

Trends come and go, but preparedness is always in fashion! Have you ever been in a situation where you desperately needed a screwdriver right away?...

Little clicky switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solderless breadboard ...

Squeeze once to turn on, squeeze again to turn off! This clicky switch makes a great power switch or mode toggler. We like this switch because it's...

Medium-sized clicky momentary switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solder...

Slim clicky momentary switches are standard input "buttons" on electronic projects. These are half the width of classic 6mm tactile switches so ...

Super-tall clicky momentary switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solderless ...

You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize "Uh oh, this chip has ...

Machine learning has come to the 'edge' - small microcontrollers that can run a very miniature version of TensorFlow Lite to do ML computations. Bu...

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 con...

It's a mini HDMI decoder board! So small and simple, you can use this board as an all-in-one display driver for TTL displays, or perhaps decodi...

A Feather board without ambition is a Feather board without FeatherWings! Spice up your Feather project with a beautiful 2.4" touchscreen display s...

The Art of Electronics 2nd Edition by Paul Horowitz & Winfield Hill HARDCOVER. Considered the best resource, now available at Adafruit. This is...

We absolutely love The Art of Electronics by Paul Horowitz and Winfield Hill. So much so, our Ladyada (Limor Fried, founder and engineer of Adaf...

We love playing with obscure materials that have a creepy-cool or magical quality. Sure, there's invisible ink, but have you ever used heat to make...

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. So far we've carried the very nice MAX31855 whi...

Thermocouples are best used for measuring temperatures that can go above 100°C. This is a bare wires stainless-steel tip probe which can measure...

These 1mm thick double-sided foam tapes are perfect for a variety of small projects. These adhesive rectangles provide a strong bond to most surfac...

Listen up! This 1.5" diameter speaker cone is the perfect addition to any audio project where you need an 8Ω impedance and are using 0.25W of po...

We're keepin' it wheel with this one! Plastic gear-box motors (also known as 'TT' motors) are an easy and low cost way to get your projects movi...
