LED Gumball Machine

We can see electricity in action on our computers, lighting our houses, as lightning strikes in thunderstorms, but what is it? This is not an easy question, but this tutorial will shed some light on it!

Not working as expected? In this tutorial, we will be exploring a few general troubleshooting tips and possible solutions that frequently come up with SparkFun's Technical Support.

Use RealVNC to connect to your Raspberry Pi to control the graphical desktop remotely across the network.

An introduction to MQTT, one of the main communication protocols used with the Internet of Things (IoT).

This guide contains all the information you will need to explore the twelve circuits of the SparkFun Inventors Kit for micro:bit.

The Qwiic Distance Sensor - VL53L1X is a time of flight sensor that is capable of several modes, as well as having a range of 4M. It's cousin VL53L4CD is also a time of flight sensor with similar characteristics but it has a range of about 1.3M. Let's hook it up and find out just how far away that thing over there is.

The Melexis MLX90640 contains a 32x24 array of thermopile sensors creating, in essence, a low resolution thermal imaging camera. In this guide, we’ll go over how to connect your Qwiic Infrared Array with MLX90640 and get it communicating with Processing to produce a nice thermal image.

Get started with the Acconeer A111 SDK with a Raspberry Pi! The tiny A111 pulsed coherent radar (PCR) adds high-precision, cutting-edge distance measurement for speed-, material-, motion-, or gesture-sensing projects! We’re not talking about simple ultrasonic, or even infrared sensors here, but 60GHz radar!
