Infrared LEDs are used for remote controls (they're the little LED in the part you point at your TV) and 'night-vision' cameras, and these little blue guys are high powered ones! They are 940nm wavelength, which is what nearly all devices listen to...

For advanced DotStar LED fans, Adafruit now has a bendable, Flexible 16x16 Dotstar LED Matrix! Control all 256 ultra-bright LEDs using only two microcontroller pins, set each LED as you wish to scroll messages or draw little images. This matrix has...

650nm 5V Laser Diode Laser Transmitter Module Product Description - Operating voltage: 5V - Size: 15 * 24 mm - Source wavelength: 650 nm - Weight: 2.2 g - Laser head sensor module KY-008

These are very bright LEDs. They are so bright that it hurts to look directly at them. Please take a look at the pictures to get an idea of the intensity. The lense is clear, but this model is red. Features 9,000mcd brightness Standard size - T1...

These are our favorite general-purpose LED's. Light up your project! Pack of 10 diffused red LEDs 5mm diameter 30° viewing angle 631nm wavelength 1.8V Forward Voltage, at 2mA current 50 mcd brightness rating

These are our favorite general-purpose LED's. Light up your project! Pack of 10 diffused green LEDs 5mm diameter 30° viewing angle 570nm wavelength 1.8V Forward Voltage, at 2mA current 38 mcd brightness rating

These are our favorite general-purpose LED's. Light up your project! Pack of 10 diffused yellow LEDs 5mm diameter 30° viewing angle 588nm wavelength 1.8V Forward Voltage, at 2mA current 50 mcd brightness rating

Infrared (IR) break-beam sensors are a simple way to detect motion. They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that same light. When something passes between...

Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75" (44.5mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to...

Be the belle of the ball with the NeoPixel Jewel!  We fit seven of our tiny 5050 (5mm x 5mm) smart RGB LEDs onto a beautiful, round PCB with mounting holes and a chainable design to create what we think is our most elegant (and...

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 rainbow, from red to orange to yellow, etc till they get...

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 diffused. 2.0-2.4VDC forward drop Max current: 20mA...

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 breadboard and will add that extra zing to your project...

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 breadboard and will add that extra zing to your project...

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, there are decimal points on each digit and an extra wire...

Diffused 5mm tri-color LEDs with separate red, green and blue LED chips inside! Nice indicator, and fun to color-swirl. 60 degree viewing angle.  These are Common-Anode type which means you connect one pin to 5V or so and then tie the other three...

Round and round and round they go! 12 ultra bright smart LED NeoPixels are arranged in a circle with 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...

Need some really bright LEDs? We are big fans of these clear green LEDs, in fact we use them exclusively in our kits. They are very bright and have about 20degree LED beam. They go easily into a breadboard and will add that extra zing to your project. ...

These strips have 30 digitally-addressable pixel LEDs per meter and are very affordable and are only 12.5 mm wide, 10 mm if you remove the strip from the casing. This is the strip with black flex PCB, its identical to the white 30 LED/meter except it has...
