Building R2-D2 – An Introduction
Building R2-D2 has been a lifelong dream of mine. It's been on the playbook and my backlog of projects for many years. Quite frankly, there are a few simple reasons that I haven't gotten to this project until ...
What is PWM or Pulse Width Modulation?
One of the first questions people new to Raspberry Pi or Arduino projects usually ask is "What is PWM?" or "What is Pulse Width Modulation?" In this quick tutorial we will quickly cover this topic and hopefully...
Easy Arduino Dice Circuit
In this project tutorial we're going to build a super easy Arduino dice circuit. It's a great learning project and one of the first project a lot of people new to the Arduinos or micro-controllers in general li...
Controlling an Arduino from a Web Page
When I got my first Arduino the first thing I thought was "Wow! I'd love to be able to control this thing from a web page!", but of our course I didn't have an Ethernet shield. So recently I decided to grab a s...
Which Multimeter to Buy?
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...
Using Arduino Temperature Sensors DHT11 and DHT22
Having your Arduino aware of temperature and humidity adds some really neat real world use cases for your Arduino projects, so in this tutorial we will focus on using Arduino temperature sensors in our projects...
Arduino LCD Display Wiring
One of the first projects many people like to do with an Arduino is wiring up an LCD display and programming it. This is because LCD screens have so many applications in the real world. You can display informa...
Arduino Train Crossing Project
In this project we're going to put together a simple Arduino train crossing! While practically this project is simply to help you learn how to use buttons, LEDs, and servos in your Arduino project, this train c...
Arduino Traffic Light Project
One of the very first projects almost all people do when they get an Arduino is to make the traffic light project. It's an incredibly simple project but it teaches you some of the most relevant fundamentals of ...
ADS-B Using a Raspberry Pi Flightradar24
If you're not familiar with Flightradar24, you should be! It's a fantastic service that tracks flights all over the world using ADS-B data. You can track ADS-B using a Raspberry Pi and send the data automatical...
