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.

Let's have some fun with LEDs! We'll explore LEDs once again with the SparkFun RedBoard Qwiic, making cool effects, and putting those effects to work using a sensor.

An introduction to polarity in electronic components. Discover what polarity is, which parts have it, and how to identify it.

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!

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.

How to design a PCB in EAGLE using through-hole parts.

An overview of the Bluetooth wireless technology.

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

The VEML6030 is a high accuracy ambient light sensor with 16-bit resolution. This I2C sensor can detect light similar to the human eye response. Start detecting light levels in your environment!

Learn how to build a simple paper circuit using copper tape, a 5mm LED, and a 3V coin cell battery.

Introducing fundamental digital logic concepts and LogicBlocks

Use GPS to have two objects, a base and a target, point towards one another. This can be used to aim a directional antenna (or in the case of this project, a laser) from one object to the other object at a distance that is only limited by your ability to provide the base station with the target's GPS location.

Building a gyrator-based analog equalizer using the Proto Pedal.

The PIC-based serial enabled character LCD backpack is a simple and cost effective solution for interfacing to character Liquid Crystal Displays (LCDs) based on the HD44780 controller. The backpack simplifies the number of wires needed and allows your project to display all kinds of text and numbers.

How to use and customize the SparkFun OpenPIR motion sensor.

In this tutorial, we look at various methods for running a script or program automatically whenever your Raspberry Pi (or other Linux computer) boots up.

Use computer vision to detect faces and project images on top of them.

An introduction into series and parallel circuits.

A simple project using the Qwiic Keypad and the RedBoard Turbo to create your own custom hotkey-pad.

Learn how to turn our 64x64 RGB LED Matrix Panel into a display for your current Spotify album art using an ESP32.

This tutorial provides everything you need to know to make your own light up high top sneakers!
