Wouldn't it be cool to drive a tiny OLED display, read a color sensor, or even just flash some LEDs directly from your computer?  Sure you can program an Arduino or Trinket to talk to these devices...

This DC-DC 12V to 3.3V 5V 12V Power Module Multi Output Voltage Conversion is also known as Buck Converter or also as Step-Down Voltage Converter. The module is capable of altering the output of...

16mm Metal Annular Push Button Switch - 3-6V - Momentary - Flat Head - Green LED Ring These chrome-plated metal buttons are rugged and look real good while doing it! Simply drill a 16mm hole into...

By popular request, you can now get our 7-segment LED backpacks without the LEDs! These backpacks feature an HT16K33 I2C LED driver, they're simple and easy to use - you can use our very nice library...

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...

Sew a little sparkle into your wearable project with an Adafruit LED Sequin. These are the kid-sister to our popular Flora NeoPixel, they only show a single color and they don't have digital control,...

Our popular Raspberry Pi Ultimate Kits include an assortment of components for circuit building. These are very handy components, so we've made them available as a separate item :) Included...

Split core current transformer are sensors that are used for measuring alternating current. They are particularly useful for measuring whole building electricity consumption (or generation for that...

This is the BC337, an NPN silicon BJT (Bipolar Junction Transistor). This little transistor can help in your project by being used to help drive large loads or amplifying or switching applications...

You have some electrons over here, and you want them over there but you don't want the electrons from over there to be able to come over here? That's what a diode is for, these are directional...

These are high quality Single Pole - Double Throw (SPDT) sealed relays. Use them to switch high voltage, and/or high current devices. This relay's coil is rated up to 12V, with a minimum switching...

What's better than a single LED? Lots of LEDs! A fun way to make a small display is to use an 8x8 matrix or a 4-digit 7-segment display. Matrices like these are 'multiplexed' - so to control all the...

An anemometer is a device used for measuring wind speed, and is a common weather station instrument. This well made anemometer is designed to sit outside and measure wind speed with ease. To use,...

The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straightforward to use. The two large, exposed pads...

The long awaited BME680 from Bosch gives you all the environmental sensing you want in one small package. This little sensor contains temperature, humidity, barometric pressure, and VOC gas sensing...

This is a highly integrated round-shaped all-in-one capacitive fingerprint sensor module, which is nearly as small as a nail plate. The module is controlled via UART commands, fairly easy to use...

This is a great general purpose-actuator for tiny mechanisms. The FS90 offers positive control over a 120 degree angle. Operating angle controlled by standard servo pulses between 900us and 2100us...

A button is a button, and an LED is a LED, but this LED illuminated button is a lovely combination of both! It's a medium sized button, large enough to press easily but not too big that it gets in...

This thumbstick is an analog joystick - more accurate and sensitive than just 'directional' joysticks - with a 'press in to select' button. Since it's analog (potentiometers), you'll need two...
