Learn the differences between AC and DC, the history, different ways to generate AC and DC, and examples of applications.

A general guide to the OBD-II protocols used for communication in automotive and industrial applications.

DMX512 is an industry standard in lighting and stage design, whether it be controlling lights, motors, or lasers, DMX512 has many uses. In this tutorial we’ll cover DMX512 (Digital Multiplex with 512 pieces of information).

Using WiFi to send sensor data from an ESP32 to a WiFi network and be able to read it from an IoT Dashboard from anywhere in the world.

The u-blox NEO-M8U is a powerful GPS units that takes advantage of untethered dead reckoning (UDR) technology for navigation. The module provides continuous positioning for vehicles in urban environments and during complete signal loss (e.g. short tunnels and parking garages). We will quickly get you set up using the Qwiic ecosystem and Arduino so that you can start reading the output!

Get started measuring indoor air quality with the SparkFun Air Quality Sensor - SGP40 (Qwiic) Hookup Guide.

The MicroMod Qwiic Pro Kit was designed to allow users to get started with Arduino without the need for soldering or a breadboard. We've included three inputs (a joystick, accelerometer, and proximity sensor) and one display that can be daisy chained to the MicroMod SAMD51 Processor Board.

This tutorial will take your SparkFun Qwiic Ultrasonic Distance Sensor to the next level by turning it into a parking distance sensor!
