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...

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 (5.8 cm x 5.6 cm x 2.4 cm) Weight: 1.34 oz (38 g)

The DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly...

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 are...

The Sharp distance sensors are a popular choice for many projects that require accurate distance measurements. This IR sensor is more economical than sonar rangefinders, yet it provides much better performance than other IR alternatives. Interfacing to...

The Raspberry Pi 3 Paddle Breakout Kit enables you to bring the Raspberry Pi B+/2/3 GPIO out from your Raspberry Pi to a 'push wire' paddle terminal board! This kit requires absolutely no soldering, but will allow you to jump straight from the Pi to...

The Raspberry Pi YouTube Workshop kits is a selection of components that was chosen to accompany a series of step-by-step video tutorial posted on YouTube. It demonstrates how to use the Raspberry Pi's inputs and outputs, and how to program using Python...
