Tutorials

Using the ESP32 to make a web-configured timed relay.

The SparkFun Arduino ProtoShield PCB and ProtoShield kit lets you customize your own Arduino shield using whatever custom circuit you can come up with! This tutorial will go over its features, hardware assembly, and how to use the shield with an Arduino R3 footprint.

A tutorial for connecting the Garmin LIDAR-Lite v3 or the LIDAR-Lite v3HP to an Arduino to measure distance.

In this tutorial, we will replace the 12V/5V (2A) power supply's molex connector with two male barrel jacks adapters.

This tutorial will show you how to make a scale that logs your weight to a custom website on the Internet. The principles can be extrapolated to any type of data.

A quickstart guide for the micro:bit educator lab pack.

The Panasonic GRID-Eye (AMG88xx) 8x8 thermopile array serves as a functional low-resolution infrared camera. This means you have a square array of 64 pixels each capable of independent temperature detection. It’s like having thermal camera (or Predator’s vision), just in really low resolution.

Figure out how magnetic fields are oriented, all without having to solder a thing.

This tutorial will show you how to make a robot that streams a webcam to a custom website that can be remotely controlled.

Tinkercad is a great, easy-to-use online modeling software that can have you 3D printing quickly. This tutorial will walk you through designing a simple project enclosure.

Figure out how things are oriented with the robust 9 degrees of freedom (DOF) BNO080 IMU. Maybe even make your own virtual reality (VR) applications if you're feeling savvy.

A hookup guide for the Noisy Cricket Stereo Amplifier - 1.5W.

Add sound effects to your project, prop or costume with Papa Soundie Audio Player.

Add sound effects to your project, prop or costume with Little Soundie Audio Player.

This guide will show you how to configure a Raspberry Pi as an access point and connect it to your local Ethernet network to share Internet to other WiFi devices.

Configure a Raspberry Pi without a keyboard, mouse, or monitor.

Learn how to hook up the LilyPad Tri-Color LED and use a common anode RGB LED in e-textile projects.

In this tutorial, we will learn about how to create an interactive theatrical prop for a performance by 3D printing a translucent diamond prop using a non-addressable RGB LED strip and AT42QT1011 capacitive touch sensing.

The addressable (UCS1903) LED neon flex rope adds cool lighting effects for outdoor and indoor uses including in hallways and stairs, holiday lighting, and more! In this hookup guide, you will learn how to connect, power, and control the LED segments with an Arduino and the FastLED library.

The TFMini is a ToF (Time of Flight) LiDAR sensor capable of measuring the distance to an object as close as 30 cm and as far as 12 meters! The TFMini allows you to integrate LiDAR into applications traditionally reserved for smaller sensors such as the SHARP GP-series infrared rangefinders.

Hot-air stations or heat guns are very useful tools and are essential for any electronics workbench. When working with or building printed circuit boards, there is a lot of room for errors to be made. Have no fear though, there are ways to remedy this with a hot air rework station!

Freescale’s MMA8452Q is a smart, low-power, three-axis, capacitive micro-machined accelerometer with 12-bits of resolution. It’s perfect for any project that needs to sense orientation or motion. We’ve taken that accelerometer and stuck it on a Qwiic-Enabled breakout board to make interfacing with the tiny, QFN package a bit easier.

The RFD77402 uses an infrared VCSEL (Vertical Cavity Surface Emitting Laser) TOF (Time of Flight) module capable of millimeter precision distance readings up to 2 meters. It’s also part of SparkFun’s Qwiic system, so you won’t have to do any soldering to figure out how far away things are.

Handling PCB jumper pads and traces is an essential skill. Learn how to cut a PCB trace, add a solder jumper between pads to reroute connections, and repair a trace with the green wire method if a trace is damaged.
