This is an OLED display module, 1.5inch diagonal, 128x128 pixels, 16 gray scale, with embedded controller, communicating via SPI or I2C interface. Features 128x128 high resolution 16 gray scale, better display effect Supports SPI or I2C interface,...

Pulse Sensor is a plug-and-play heart-rate sensor for Arduino. Heart rate data can be really useful whether you're designing an exercise routine, studying your activity or anxiety levels or just want your shirt to blink with your heart beat. The problem...

Your power supply problems just got SOLVED! This little circuit board may look tiny but inside is a high efficiency DC/DC step-down converter which can output up to 3 Amp at 5V without the need of any heat-sink or forced cooling. (It does get a bit...

Bring a little bit of Times Square into your home with this sweet 64 x 32 square RGB LED matrix panel. These panels are normally used to make video walls. In New York, Adafruit sees them on the sides of busses and bus stops, to display animations or...

Sew a little sparkle into your wearable project with an Adafruit LED Sequin. These are the kid-sister to the popular Flora NeoPixel, they only show a single color and they don't have digital control, but that makes them smaller easier to use for many...

These LED strips come in 5 meter reels. These strips are sold by the meter! If you buy 5 meters at a time, you'll get full reels. If you buy less than 5m, you'll get a single 1-4m strip. 1. Light source:  5050 SMD LED strip. 2. Waterproof : IP65 3...

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 seven-segment LEDs you need 14 pins. That's a lot of...

This alcohol gas sensor detects the concentration of alcohol gas in the air and ouputs its reading as an analog voltage. The concentration sensing range of 0.04 mg/L to 4 mg/L is suitable for breathalysers (the legal limit of breath alcohol...

This flammable gas and smoke sensor detects the concentrations of combustible gas in the air and ouputs its reading as an analog voltage. The sensor can measure concentrations of flammable gas of 300 to 10,000 ppm.The sensor can operate at temperatures...

This Carbon Monoxide (CO) gas sensor detects the concentrations of CO in the air and ouputs its reading as an analog voltage. The sensor can measure concentrations of 10 to 10,000 ppm.The sensor can operate at temperatures from -10 to 50°C and consumes...

This breakout board is designed to work with any of the MQ-series gas sensors, simplifying the interface from 6 to 3 pins—ground, +5V VCC, and an analog voltage output—that are broken out with a 0.1" spacing, making the board compatible...

The Kitronik Klip Halo for the BBC microbit breaks out all of the pins from the microbit to pads spaced around the edge of the Klip Halo. The pads have been carefully designed and spaced so that they are ideal for for use...

Add some colour to your next coding project with our new Halo board for the BBC micro:bit. The Halo has 24 ZIP LEDs, which are individually addressable full colour LEDs. This means that each LED can display a huge spectrum of colours, allowing amazing...

Round and round and round they go! 24 ultra bright smart LED NeoPixels are arranged in a circle with 2.6" (66mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to...

Put on your sunglasses before wiring up this LED matrix - 64 eye-blistering RGB LEDs adorn the NeoMatrix for a blast of configurable color. Arranged in an 8x8 matrix, each pixel is individually addressable. Only one microcontroller pin is required to...

The Squid Button makes it super easy to attach a push switch to a Raspberry Pi. Note: Switch and lead colors may vary The Squid Button is in fact a momentary action push switch with trailing leads that end in female header sockets that will...
