A button is a button, and an LED is a LED, but this LED illuminated button is a lovely combination of both! It's a medium sized button, large enough to press easily but not too big that it gets in the way of your project panel. It has a built in LED that...

Adafruit 3296 - DS1307 Real Time Clock Assembled Breakout Board This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for...

Adafruit 997 - Plastic Water Solenoid Valve - 12V - 1/2" Nominal  Control the flow of fluid using the flow of electrons! This liquid valve would make a great addition to your robotic gardening project. There are two 1/2" (Nominal non-taped National...

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

Simple but effective - this sewable breakout board has a CR2032 coin cell battery holder soldered on and 0.1" pitch breakout pins for easy connecting. Great for powering very low-current projects, or adding a battery backup circuit to a real-time-clock...

Adafruit 780 - Diffused Blue 3mm LED (25 pack) 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...

Share a USB 3 device between two hosts or switch between two devices on one host. The bidirectional USB 3 Mux allows either a single USB device (or multiple devices when using a USB hub) to be switched between two USB hosts (computer) or using its...

The USB Switch/Multiplexer allows a USB device (or multiple devices if connected via a USB hub) to be switched between two hosts, or powered off. This newer 4-pin version adds a 3.3V output which can be used to toggle the state using switches without the...

The 8086 USB-USB NULL Modem (UUNM) is a back-to-back USB to Serial converter using USB CDC Serial - meaning drivers are already built in to most modern operating systems (Linux/Windows 10/Mac OS X/Android) so you can just plug n' play! Users The...

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 gasket to keep water out of the enclosure. On the front of...

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 VDC and press the buttons on your RF keyfob remote. When the A button is...

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...

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:...

Medium-sized clicky momentary switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solderless breadboard as shown in this tutorial. The pins are normally open (disconnected) and when the button is...

PIR sensors are used to detect motion from pets/humanoids from about 5 meters away (possibly works on zombies, not guaranteed). This sensor is much smaller than most PIR modules, which makes it great for unobtrusive projects. It's also fully-contained -...

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...

These nice switches are perfect for use with breadboard and perfboard projects. They have 0.1" spacing and snap in nicely into a solderless breadboard. They're easy to switch no matter what size fingers you have, but not so easy that they'll get flipped...

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 breadboards or perfboards. They will work where "thick pin"...

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...

This rotary encoder is the best of the best, its a high quality 24-pulse encoder, with detents and a nice feel. It is panel mountable for placement in a box, or you can plug it into a breadboard (just cut/bend the two mechanical side tabs.) We also...
