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,...

Make your own USB connections without slicing apart a USB cable and soldering those thin wires inside. These DIY "USB shells" are available in USB A plug, micro B, mini B and USB A socket. Each...

If you have a project where you'd like to be able to detach the wiring, this wire will fit the bill. Its a JST 2.5mm 'free hanging' cable assembly that latches strongly. One wire is marked with a...

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...

This power jack is designed to fit 2.1mm power plugs snugly and securely. Perfect for adding a power connector to your project. We went for the more expensive "thin pin" type which snap into...

Add a bunch of high-power outputs to a microcontroller system with chainable shift registers. These chips take a serial input (SPI) of 1 byte (8 bits) and then output those digital bits onto 8 pins...

These chrome-plated metal buttons are rugged and look real good while doing it! Simply drill a 16mm hole into any material up to 1/2" thick and you can fit these in place, there's even a rubber...

Sensor tip is 2" Chip: DS18B20; Voltage: 3.0~5.5V Temperature range: -55'C~+125'C (-67'F~+257'F) Output wires: Red(VCC), Yellow (DATA), Black(GND)

This mini-kit makes it easy to mount a PSP/Xbox-like thumb joystick to your project. The thumbstick is an analog joystick - more accurate and sensitive than just 'directional' joysticks - with a...

The Raspberry Pi has an on-board audio jack, which is super handy for all kinds of sound effects and speech, just plug and go! However, for when you want better audio for music playback, a USB audio...

Bosch has stepped up their game with their new BME280 sensor, an environmental sensor with temperature, barometric pressure and humidity! This sensor is great for all sorts of indoor environmental...

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...

Tiny little servo can rotate approximately 180 degrees (90 in each direction), and works just like the standard kinds you're used to but smaller. You can use any servo code, hardware or library to...

5V Four Channel SSR Solid Relay Module 240V / 2A - High Level Trigger - For Arduino Specifications Max. LoadAC: 240V Input Voltage: 5V DC Trigger Current: 2mA Dimensions: 2.28 in x 2.2 in x 0.94 in...

This here is a 10 pack of the classic 1N4001 power blocking diode. These are good for reverse polarity protection (put it between your DC power jack and circuitry to avoid a negative-voltage that...

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...

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...

Transmission distance: >8m Effective angle: 60' Quiescent current: 3-5uA Dynamic current: 3-5mA Ideal for Arduino DIY project 17-key IR remote control Transmit 38KHz modulating...

This is a 5V 8-Channel Relay interface board able to control various appliances, and other equipment with large currents. It can be controlled directly by Micro-controller (Raspberry Pi, Arduino,etc...

If you're like me, you've dreamed of being a dolphin - smoothly gliding through the water. Using your echo-location abilities to detect tasty fish treats. Until genetic modifications catches up with...
