Connect this to that without soldering using these handy mini alligator clip test leads. 15" cables with alligator clip on each end, color coded. You get 12 pieces in 6 colors. Strong and grippy, these always come in handy! We often use these in...

Simple but effective - this breakout board has a USB Micro-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. We use a micro-AB connector with through-hole shielding...

Need some really bright LEDs? We are big fans of these clear red 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...

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...

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...
