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 […]
My wife bought this cool house on the lake. And we really love it. But it has one problem that drives us nuts: The cell phone coverage in the area is terrible! When we’re in the backyard, or on our dock there is generally no cell phone coverage and therefore no data. Now I get […]
In this Geek Pub Recommendation we’re going to cover what we believe are the best arcade joystick and buttons you can buy. We’re going to cover some of the basics of what makes them good or bad, what to look out for, and the different types of arcade controls. There are probably a few reasons […]
In this Arduino limit switch tutorial, we’re going to talk about how to use the limit switch within our Arduino projects. The limit switch is a fantastic tool for use in projects that have motion control and automation. The limit switch can be used to tell the Arduino that a stop point has been reached. […]
The Arduino force sensor is a super neat sensor that you can use in your projects to measure if something is being pressed upon and to what degree. The force sensor is used in many devices that you might not expect. For example the drum pad! When you tap on a drum pad there is […]
Welcome to Pub Talk Episode 5! Oh boy do we have a ton of updates for this one! In this Episode of Pub Talk we discuss the following: 00:00 – Welcome 00:50 – Can you help tell me how spammers rank their pages over mine using stolen content? 03:10 – About the Geek Bits Podcast […]
Arduino RGB LED configuration! That’s what we’re covering in this tutorial! Most of the time you will be using LEDs that are a single color. Red, green, or blue for example. an RGB LED is basically three LEDs in one that can produce many thousands of colors! Please note this tutorial is not about WS2812b […]
The Arduino is a fantastic little piece of hardware. The little Atmega microcontroller under the hood is capable of some amazing stuff! In this tutorial, we’re going to learn how to convert a string to an Integer on the Arduino! And in the case that you are using a character array, we’ll also learn how […]
It’s often as a beginner that you will need to learn the art (and science) of combining two Arduino sketches (code) into a single sketch. Sketches are the name Arduino calls their code or program files. It’s not as simple as copying and pasting one sketch into the other. This will fail to compile and […]
In this tutorial we will cover the basics of the Arduino touch sensor. It’s one of the fundamental input devices available for the platform. I a touch sensor simply put senses when it comes in contact with a human, be it finger, toe, or even your nose. The touch sensor can be substituted in many […]
