PIR sensors are used to detect motion from pets/humanoids from about 5 meters away (possibly works on zombies, not guaranteed). This sensor is much smaller than most PIR modules, which makes it great...

Simple but effective - this breakout board has a USB Mini-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...

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...

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...

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...

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...

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

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...

Make a scrolling sign, or a small video display with this 8x8 gridded pixel white LED matrix. Only 1.2" on a side, it is quite visible but not so large it won't plug into a breadboard! There are...
