Learn how to build a wireless controller to kill power when things go... sentient.

With this, you will be able to upload Arduino sketches directly to the ATtiny84 over USB without needing to use a programming device (such as another Arduino or FTDI chip).

How to install CH340 drivers (if you need them) on Windows, Mac OS X, and Linux.

How to install drivers for the FTDI Basic on Windows, Mac OS X, and Linux.

How about that humidity? This tutorial shows how to add sensing capability to the 21st Century Fashion Kit's RGB flower project.

The HX1 is a low-power amateur radio transmitter that can be used to send data to the Automatic Packet Reporting System (APRS) network.

Hookup guide for the MAX98357A I2S audio breakout board.

Fix your bootloader-less MicroView! This tutorial covers how to: disassemble the MicroView, wire it up to an assortment of programmers, program the bootloader, and test it out.

This tutorial will teach you what a bootloader is and why you would need to install or reinstall it. We will also go over the process of burning a bootloader by flashing a hex file to an Arduino microcontroller.

How do I install a custom Arduino library? It's easy! This tutorial will go over how to install an Arduino library using the Arduino Library Manager. For libraries not linked with the Arduino IDE, we will also go over manually installing an Arduino library.

A step-by-step guide to installing and testing the Arduino software on Windows, Mac, and Linux.

How do I install a custom Arduino board/core? It's easy! This tutorial will go over how to install an Arduino board definition using the Arduino Board Manager. We will also go over manually installing third-party cores, such as the board definitions required for many of the SparkFun development boards.

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.

Learn how we converted 72 lightbulbs into an interactive LED array for our conference room.

Use an Arduino and the SparkFun Sound Detector to create visualizations on Addressable RGB LED strips.

The SparkFun ESP8266 Thing Dev Board is a powerful development platform that lets you connect your hardware projects to the Internet. In this guide, we show you how to combine some simple components to remotely log temperature data, send yourself texts and control lights from afar.
