The place to learn about all things geek!
In our first tutorial about basic electricity, you learned that current is just the flow of electrons in a wire. You learned about current and that its unit of measurement Amps refers to how many electrons are flowing past a certain point per second. In this tutorial we’re going to answer the questions you’ve all […]
This is new set of tutorials on the basics of electricity. I am often asked some of these questions, and I thought it would a great idea to have a place to share and send people to for the answers. Today we’re going to answer the question “What is current?” It’s a confusing topic and […]
In this tutorial, its all about Teensy vs. Arduino! What’s the difference? Why use a Teensy over an Arduino or vice-versa? We will touch on the basics and then dive into a few key areas to help you understand when you should use one over the other. Both are fantastic platforms with lots applications and […]
In this tutorial, we’re going to cover using the the DHT11 (or DHT22) temperature and humidity sensor with the Raspberry Pi. Using the DHT11 temperature sensor with the Raspberry Pi is a great way to get temperature and humidity readings in your projects. Especially to keep tabs on how hot your Raspberry Pi is, if […]
In this article, we’re going to do an Arduino water level sensor tutorial. We’ll go over how to wire the sensor, how it works, and some basic code examples to get you started in your projects. This sensor is also sometimes referred to as a water leak detection sensor. Watch the Arduino Water Level Sensor […]
In this tutorial, we’re going to show how to do the most awesome Arduino Knight Rider LEDs! It’s a highly requested article after our last update on blinking a single LED we sneak peaked this and apparently, everyone wants to know more! For those who might not know, Knight Rider is a TV show from […]
After my last video introducing the Arduino, some of you commented that you needed an example of how the Arduino works that is super simple to understand. So in this video we’re going to do the absolute simplest of projects. We’re going to be blinking an LED! Arduino: Blinking an LED Video We’ve made detailed […]
In this tutorial, we’re going to do an introduction to the Arduino! I think a lot of people confuse them with the Raspberry Pi line of single board computers, and they are very different products that do similar but different things. I’m sure if you’re even the slightest bit geeky or at all into DIY […]
Many people pour hours and hours into developing a project on their Raspberry Pi and never put any though in how to back up their work. A Raspberry Pi is a used a lot for prototyping and electronics learning projects. It’s a super fantastic computer for these purposes and even includes a full set of […]
The ultrasonic sensor is one of the most common sensors used in Arduino projects. It’s one of those must have sensors for many projects that require inputs for navigation. For example, an Arduino RC car or other robot will likely need an ultrasonic sensor to measure how close it is to a wall or other […]
