Micro-switches are often found in arcade buttons and joysticks but they're also really handy in any kind of mechatronics project or when you need a basic sensor. They are always 'tactile' (clicky...

Medium-sized clicky momentary 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...

The Adafruit Push-button Power Switch is a tidy little design that lets you control a DC power source using an everyday tactile button. The breakout uses a latching analog circuit that is triggered...

This distance sensor bounces IR off objects to determine how far away they are. It returns an analog voltage that can be used to determine how close the nearest object is. Comes with 12" long 3-JST...

These 3-wire cables are 163mm (6.4") long and come as a set. One cable has a JST SM type connector plug on the end. The other cable has a matching JST SM type receptacle connector. They are good for...

These are very interesting 5mm diffused RGB LEDs - instead of having 4 pins to control 3 LEDs, they have only two leads - power and ground. When powered, the LEDs perform a slow fade through the...

Spin two DC motors, step one bi-polar or uni-polar stepper, or fire off two solenoids with 1.2A per channel (3A peak) using the TB6612. These are perhaps better known as "the drivers in our assembled...

LEDs - those blinky things. A must have for power indication, pin status, opto-electronic sensors, and fun blinky displays. This is a very standard, yellow LED. The lens is 3mm in diameter and it is...

Need some indicators? We are big fans of these diffused green LEDs, as featured in the LoL shield. They are fairly bright so they can be seen in daytime, and from any angle. They go easily into a...

Need some indicators? We are big fans of these diffused blue LEDs, as featured in the LoL shield. They are really bright so they can be seen in daytime, and from any angle. They go easily into a...

PowerBoost is the perfect power supply for your portable project! This little DC/DC boost converter module can run from 1.8V batteries or higher, and convert that voltage to 5.2V DC for running your...

Solenoids are basically electromagnets: they are made of a big coil of copper wire with an armature (a slug of metal) in the middle. When the coil is energized, the slug is pulled into the center of...

Adafruit 2471 - HUZZAH ESP8266 Breakout Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz...

These chrome-plated metal buttons are rugged and look real good while doing it! Simply drill a 16mm hole into any material up to 1/2" thick and you can fit these in place, there's even a rubber...

Keep your 5mm LEDs in place with these little plastic LED holders. These are handy for projects using individual LEDs as they look sleek, and your LED won't budge. Slot the LED through the...

These chrome-plated metal buttons are rugged and look real good while doing it! Simply drill a 16mm hole into any material up to 1/2" thick and you can fit these in place, there's even a rubber...

An IC (Integrated Circuit) socket allows you to insert and remove chips easily from an assembled kit or project This item contains 3 of the 28 pin 0.6" wide version. Best used with chips that have...

Design a clock, timer or counter into your next project using our pretty 4-digit seven-segment display. These bright crisp displays are good for adding numeric output. Besides the four 7-segments,...

Make your own USB connections without slicing apart a USB cable and soldering those thin wires inside. These DIY "USB shells" are available in USB A plug, micro B, mini B and USB A socket. Each...

Add a bunch of high-power outputs to a microcontroller system with chainable shift registers. These chips take a serial input (SPI) of 1 byte (8 bits) and then output those digital bits onto 8 pins...
