Need to add analog inputs? This chip will add 8 channels of 10-bit analog input to your microcontroller or microcomputer project. It's super easy to use, and uses SPI so only 4 pins are required. We chose this chip as a great accompaniment to the...

Not just a simple breakout board, this microSD adapter goes the extra mile - designed for ease of use. Onboard 5v->3v regulator provides 150mA for power-hungry cards 3v level shifting means you can use this with ease on either 3v or 5v...

Description: This is a simple six wire cable. Great for jumping from board to board or just about anything else. There is a 6-pin JST RE connector on both ends. These are simple jumper wires used on standard 0.1" breakaway headers. Dimensions: 12" length

This is the Magnetic Door Switch Set, a small reed switch assembly specifically designed to alert you when doors, drawers, or any other aperture opens. These types of switches are primarily used in home security systems. One half of the assembly set on a...

Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V. We do have some other...

These are our favorite trimpots, perfect for breadboarding and prototyping. They have a long grippy adjustment knob and with 0.1" spacing they plug into breadboards or perfboards with ease. This is the same pot that comes with our character LCDs and...

Nothing makes a project harder to maintain than a lot of loose wiring. That's why we like to use terminal blocks whenever making PCB-to-Wire connections. These particular 3.5mm terminal blocks are our favorite: big enough for a range of wire gauges, easy...

This potentiometer is a two-in-one, good in a breadboard or with a panel. Its a fairly standard linear taper 10K ohm potentiometer, with a grippy shaft. Its smooth and easy to turn, but not so loose that it will shift on its own. We like this one because...

Oh say can you see By the knob's early light... Sorry - we thought that was clever.  And while it wasn't really, this potentiometer knob definitely is.  It's a 'soft touch' T18 knob that works great with our Panel Mount 10K potentiometers...

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...

Need some really bright LEDs? We are big fans of these clear blue LEDs, in fact we use them exclusively in our kits. They are very bright and have about 20 degree 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...

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...

This Passive Buzzer provides an easy way to add sound to your electronics projects. Breadboard-friendly with a 7 mm pin pitch, it generates tones when driven with a signal. Useful for alerts, effects, or interactive designs, it operates from 6–24...
