Build a convincing artificial fire effect for the holiday season using NeoPixel LEDs, an Arduino UNO, and a cool mist module. Story This is a project I’ve had on the backburner for almost exactly 1 calendar year. The seed was planted when I toured the Harry Potter Studios last year and saw a fake fireplace […]

With all the different ways capacitors are labeled, figuring out the values of your capacitors can be challenging. Especially if you don’t have a digital multi-meter to test them. In this tutorial, I’ll show you how to build three different capacitance meters using an Arduino and a couple resistors. After finishing this project, you’ll be able to measure all

Ultrasonic range finders are fun little modules that measure distance. You can use them to find the distance to an object, or to detect when something is near the sensor like a motion detector. They’re ideal for projects involving navigation, object avoidance, and home security. Because they use sound to measure distance, they work just as well in the dark as

The DHT11 humidity and temperature sensor makes it really easy to add humidity and temperature data to your DIY electronics projects. It’s perfect for remote weather stations, home environmental control systems, and farm or garden monitoring systems. In this tutorial, I’ll first go into a little background about humidity, then I’ll explain how the DHT11 measures humidity. After that,
