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...

Little clicky switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solderless breadboard. The pins are normally open (disconnected) and when the button is pressed they are momentarily closed. They...

Hey want to hear a really loud noise? Apply 3V to 5V to this buzzer module and you'll be rewarded with a loud 2KHz BEEEEEEEEEEEEEEEEEP. Unlike a plain piezo, this buzzer does not need an AC signal. Inside is a piezo plus the driver circuitry that makes...

Your basic 7-segment LED. Common anode. Two decimal points, but only the one on the right is wired. Digit height is 0.6". Overall height is 1". Resources Datasheet Arduino Library (Thanks Derek!)

Description 1. The Sound Detector is based on a microphone and a power amplifier. It can be used for detecting the sound strength of the environment. 2. This sound sensor gets signal by both digital and analog output. 3. "AO" outputs real-time voltage...

Use this shield to add capacitive touch keys (like bananas or play doh!!) to your Arduino Uno. The popular Makey Makey product works this way. Specifications Suitable for 2009 Uno UNOR3 LEONLADO controller. Working voltage: 5V Interface: USB male...

This shield (an Expansion Board without XBee module) is a compliant solution designed to meet low-cost, low-power wireless sensor networks with special needs. The Xbee module is widely used in the United States, Canada, Australia, Israel and Europe...

A passive buzzer emits a tone when a voltage is applied across it. It also requires a specific signal to generate a variety of tones. Specifications Rated Voltage: DC 5V; Working Voltage: 6-24VDC Resonance Frequency: 2.8 +/- 0.5KHz; Sound Pressure:...

Continuous beep - Breadboard friendly!

Diameter:5mm Model: 5549 Light Resistance 45-140KO Dark resistance 10MO

They come in 5 meter reels with a 3-pin JST SM connector on each end and separated power/ground wires and different color wires than show in the image. These strips are sold by the meter! If you buy 5 meters at a time, you'll get full reels with two...

These Simple RF receivers are the easiest way possible to add wireless control, painlessly! There's no programming, configuring or addressing - simply power the receiver with 5-10VDC and press the buttons on the matching RF keyfob remote. When the A...

This 4-button keyfob remote goes with Adafruit's basic 315MHz RF receiver modules. It will work with all of them, sending out one of four commands that match up with the four outputs. Its small and light weight and will work up to 25 feet away depending...

  One Terminal Strip, Tie-point 25. Material: ABS plastic Completely reusable. Accepts a variety of wire sizes (29-20 AWG). Red,green,blue,yellow ,white,and black are available for...

Various flame, fire detection, relay output, which can be accessed 220V high current electrical equipment Module Features: 1, can detect the flame or the wavelength at 760 nm to 1100 nm range of the light source, the test flame lighters distance of...
