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!

An introduction into series and parallel circuits.

What is an interrupt? In a nutshell, there is a method by which a processor can execute its normal program while continuously monitoring for some kind of event, or interrupt. There are two types of interrupts: hardware and software interrupts. For the purposes of this tutorial, we will focus on hardware interrupts.

This guide will show you how to write programs on your Raspberry Pi using Python to control hardware.

OpenScale allows you to have a permanent scale for industrial and biological applications. Learn how to use the OpenScale board to read and configure load cells.

This tutorial provides information about how to connect to ADH-Tech's fingerprint scanner (GT-521F32) and how to use it with Hawley's FPS_GT511C3 library for Arduino.

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.

Running low-power machine learning examples on the SparkFun Edge can now be done using the familiar Arduino IDE. In this follow-up to the initial Edge tutorial, we'll look at how to get three examples up and running without the need to learn an entirely new SDK.
