Adafruit 0.56" 4-digit 7-segment Display W/Backpack
$11.90
What's better than a single LED? Lots of LEDs! The matrices use a driver chip that does all the heavy lifting for you: They have a built in clock so they multiplex the display. They use constant-current drivers for ultra-bright, consistent color, 1/16 step display dimming, all via a simple I2C interface. The backpacks come with address-selection...

Adafruit White LED Backlight Module - Medium 23mm x 75mm
$2.45
These pretty strips of light are plastic diffused backlights, often seen in LCD displays. Normally they're tucked behind the LCD and shine white light from below. Here, we've got the LEDs available individually. Each LED is encased in a 3.5mm thick strip of a acrylic. The acrylic strip is a special type that is very good at diffusing light, so e...

Adafruit NeoPixel Jewel - 7 x WS2812 5050 RGB LED with Integrated Drivers
$5.90
Adafruit has fit seven tiny 5050 (5mm x 5mm) smart RGB LEDs onto a beautiful, round PCB with mounting holes and a chain-able design to create what we think quite an elegant NeoPixel board. Use only one microcontroller pin to control as many as you can chain together. Each LED is addressable as the driver chip is inside the LED. Each one has ~18m...
Adafruit NeoPixel Ring - Multiple Sizes

Adafruit NeoPixel Ring - Multiple Sizes
$7.45
Ultra bright smart LED NeoPixels are arranged in a circle with either 2.6" (66mm) outer diameter or 1.5" (37mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control one, or multiples chained together. Each LED is addressable as the driver chip is inside...

Adafruit NeoPixel Digital RGB LED Weatherproof Strip 60 LED-1m
$24.90
These 12.5mm wide NeoPixel strips are exactly what you need for your next wearable product. The strip has black-colored flex PCB, which will be less visible against black-painted walls. There are 60 RGB LEDs per meter, and you can control each LED individually. You can set the color of each LED's red, green and blue component with 8-bit PWM pre...

Adafruit NeoPixel Digital RGB LED Strip - White 60 LED - WHITE - 1M
$24.90
You thought it couldn't get better than our world-famous 32-LED-per-meter Digital LED strip but we will prove you wrong! You wanted twice the LEDs? We got it (well, its 1.875 times as many but that's within a margin of error). You wanted thinner strips? Now only 12.5 mm wide, 10 mm if you remove the strip from the casing. You wanted less noticea...

Adafruit DotStar Digital LED Strip - Black 144 LED/m - 0.5 Meter - BLACK
$39.90
These new DotStar LED strips are a great upgrade for people who have loved and used NeoPixel strips for a few years but want something more versatile. DotStar LEDs use generic 2-wire SPI, so you can push data much faster and there's no specific timing required. They also have high PWM refresh rates, so you can do Persistence-of-Vision (POV) and...

Adafruit Bi-Color (Red/Green) 24-Bar Bargraph w/I2C Backpack Kit
$9.90
These LEDS are a fun way to make a small linear display is to use two 12-bar Bi-color bar-graphs. However, this LED bargraph is 'multiplexed' - so to control all the 48 LEDs you need a lot of pins. There are driver chips that can help control a bar-graph/matrix for you but there's a lot of wiring to set up and they take up a ton of space. This b...

Adafruit Medium 16x32 RGB LED matrix panel
$24.90
These 16 x 32 RGB LED matrix panels are normally used to make video walls to display animations or short video clips. They have 512 bright RGB LEDs arranged in a 16x32 grid on the front. On the back there is a PCB with two IDC connectors (one input, one output: in theory you can chain these together) and 12 16-bit latches that allow you to drive...
