In this article we’re going to cover multimeters! We’ll talk about how to use them to measure voltage, current, resistance, and continuity. We’ll go over what to look for in a multimeter, where to buy one, and give you our picks for the best multimeters you can buy. Deciding Which Multimeter to Buy? In today’s […]
In this tutorial we’re going to learn about using a 555 timer in monostable mode, but first a little history is in order! Without a doubt the 555 timer is one of the most common, if not the most common integrated circuits used on electronics over the last 45+ years. First entering production in 1971 […]
In this tutorial we’re going to learn about using a 555 timer in astable mode. We’ve talked about the longevity of the venerable 555 timer and how its been around for almost 50 years at the time of this writing. It’s an incredibly versatile little integrated circuit with many fantastic uses. In this tutorial we’ll […]
WLED is an awesome open source application created to control addressable LEDs (WS2811, WS2812b, WS2813, etc) from your iOS or Android smartphone, or literally any device which can send a command via http/https over a network! It runs on the ESP32 platform of microcontrollers, which although similar to the Arduino is different but mostly compatible […]
There are several types of grounds used in electronics projects. And sometimes these types of grounds and the words used to describe them (earth, ground, etc.) are thrown around interchangeably. But these different types of grounds are very different and it is good idea to know difference between them when building your projects. In most […]
Stepper motors are used in so many things you buy today and most people don’t even know it! They truly are amazing little pieces of electronics and mechanics combined into one. Even the vibrator built into your phone is likely based on stepper motor technology! In this tutorial we’re going to cover the basics of […]
When you flip a switch or press a button two metal contacts come together. It might seem like they make immediate contact and complete a circuit. However, in reality as they make contact they mechanically bounce, making brief contact several times before making a solid connection. In some cases this bounce can also be electrical […]
Switches are literally everywhere! They are in many of the devices we use on a daily basis and a most basic part of just about every electronics project! So in this electronics basics tutorial we’re going to cover the different types of switches and what the applications that they are used for. At its most […]
Batteries are everywhere in our lives. Not only in the products we buy, but in our electronics projects! It’s not always clear when we should use which time, or what even makes one type of battery different from another. In this tutorial we’re going to cover the different types of batteries and talk about some […]
In this tutorial, we’re going to learn how rotary encoders work! Rotary encoders (also shaft encoders) are a fantastic way to dial in a position, or determine the position of a shaft. This could be the position of a knob you are turning, or it could be an encoder connected to a stepper motor to […]
