Transistors are powerful little electronic switches, and we really like these NPN transistors whenever we need to control medium-power electronics such as small motors, solenoids, or IR LEDs. We find...

Listen up! This 1.1" (~30mm) diameter speaker is the perfect addition to any breadboard-based audio project where you need 8 Ohm impedance, and have 0.2W or less of power. The two pins are 15mm / 0...

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...

Light Sensitive Resistor GL5549

Move fluid safely from here to there with this very nice little pump. Unlike most liquid pumps, this is a peristaltic type - the pump squishes the silicone tubing that contains the liquid instead of...

Bring a little bit of Times Square into your home with this 16 x 32 RGB LED matrix panel. These panels are normally used to make video walls, but in New York you can see them on the sides of busses...

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...

Working voltage: DC5V-20V Quiescent Current: 65uA Level Output Voltage: High 3V / Low 0V Delaying time: 0.3~18s (adjustable) Blockade Time: 0.2s Trigger Method: L: unrepeatable trigger / H:...

The Raspberry Pi B+ / Pi 2 / Pi 3 / Pi 4 has landed on the Maker World like a 40-GPIO pinned, quad-USB ported, credit card sized bomb of DIY joy. And while you can use most of our great Model B...

This is the assembled version of the Pi T-Cobbler Plus.  It only works with the Raspberry Pi Model Zero, A+, B+, Pi 2,Pi 3, Pi 4! Or just any Pi with 2x20 connector. The Raspberry Pi B+ and Pi 2...

Looking for another way to keep your Raspberry Pi cool? Hook up this 5V Mini Cooling Fan and prevent your hard-working Pi from overheating! Of course, it's also great for use with any small computer...

This inexpensive USB to RS232 cable works well for Linux and Windows 7 environments, but is not currently functioning with Windows 10. Suitable for link download Simple and easy way to give USB...

This is a digital temperature and humidity sensor module that works with all of the Arduino micro-controllers. Because it is a digital sensor it only necessitates 3 connections, Vcc, GND, and a...

4pin Mini Voice Sound Sensor Module Microphone Sound module - LM393 Chip 

4-Channel Relay Module for Arduino & Raspberry Pi - 5V This is a 5V (Trigger Voltage) 4-Channel Relay module, It can be controlled directly by a wide range of microcontrollers such as Arduino, AVR,...

This is a 5V, 10A 2-Channel Relay interface board. It can be used to control various appliances, and other equipments with large current. It can be controlled directly with 3.3V or 5V logic signals...

This is a motor shield for an Arduino Uno that makes it easy for your Arduino to control various types of motors! All you need to do is attach this to your Uno, run wires from your motors to the...

This is a digital light sensor that can be used to precisely measure the ambient light level.  The sensor has a 16 Bit AD converter so it outputs a digital signal that can be read using the...

This is what is known as a Real Time Clock (RTC) module and can be used with any Arduino so that it can tell time. The Arduino does not have a RTC on board and therefore can not tell time for an...

This is a digital temperature and humidity sensor module that works with all of the Arduino micro-controllers. Because it is a digital sensor it only necessitates 3 connections, Vcc, GND, and a...
