Learn how to build your own Internet-connect, solar-powered temperature collection station using the Photon from Particle.

Measure relative humidity with SparkFun's HIH-4030 Humidity Sensor Breakout.

Tkinter is the standard graphical user interface package that comes with Python. This tutorial will show you how to create basic windowed applications as well as complete full-screen dashboard examples complete with live graph updates from matplotlib.

Classroom STEM activity that has students build a battery from a lemon, measure the open and closed circuit voltages, and determine the battery's internal resistance.

Build your very own retro gaming controller with a Raspberry Pi using the SparkFun PiRetrocade Kit!

In this tutorial, we will use a Raspberry Pi 3 and the Pi AVR Programmer HAT to program an ATMega328P target. We are going to first program the Arduino bootloader over SPI, and then upload an Arduino sketch over a USB serial COM port.

This tutorial will show you how to build a magnetic levitation circuit using common parts.

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

Turn a large voltage into a smaller one with voltage dividers. This tutorial covers: what a voltage divider circuit looks like and how it is used in the real world.
