Most orders for IN STOCK items placed by 12PM CST M-F ship SAME DAY. Orders for custom items and prints may take additional time to process.
Mike is the founder of The Geek Pub. A jack of all trades who simply enjoys the challenge creating things, whether from wood, metal, or from lines of code in a computer. Mike has created all kinds of projects that you can follow and build yourself, from many different styles of retro arcade cabinets to Arduino and Raspberry Pi projects.
One question I get asked regularly is just how to reset an Arduino using code. This sounds like something you should never need to do. But resetting an Arduino programmatically is most likely something you will eventually encounter in your Arduino journey! There are two basic types of resets for the Arduino (or just about […]
Learning how to use millis instead of delay is a key principle for learning the Arduino platform. The delay() function will cause all code executing on the Arduino to come to a complete halt and it will stay halted until the delay function has completed its delay time. We often refer to the delay() function […]
In this project, we’re going to make a cocktail table arcade cabinet that we think you’ll to love! I’ve wanted to build a cocktail table arcade since my very first arcade cabinet build back in July of 2015! A cocktail table arcade is something I always gravitated to as a kid. I think it was […]
In this Arduino tutorial, we’re going to learn the basics of how to fade an LED with a potentiometer. As you turn the knob of the potentiometer the resistance changes. The Arduino will take this readings on the connected analog pin and then software will use a PWM signal at the correct frequency to light […]
In this Arduino tutorial, we’re going to make a a circuit wherein a light sensor triggers and LED to light based on the the level of light in the room. Light sensors are actually light sensitive resistors (or photoresistors). With this type of resistor, its value resistance value changes based on the amount of light […]
In this Arduino tutorial we’re going to learn how to use a motion sensor to sound a piezo buzzer. This is great for an intrusion detection circuit or burglar alarm circuit! Any time the motion sensor senses movement the piezo buzzer will make an audible sound. In this tutorial we will use an active piezo […]
In this Arduino Tutorial we’re going to learn how to control a piezo buzzer with a button. Pressing a button on your breadboard will cause the piezo buzzer to sound. In this tutorial we will be using a active piezo buzzer. If you’d like to do this with a passive piezo buzzer you can find […]
Did you know that the Apple 1 case you see on Wikipedia is not actually the case that Jobs and Wozniak made? Indeed the Apple 1 did not come with a case at all!
A piezo buzzer is a fantastic way to add feedback to users of your projects. In this Arduino piezo buzzer tutorial, we’re going to dive into the different types of piezo buzzers, how they work, how to wire them up to your Arduino, and write a sketch to control them. Before you know it, piezo […]
In this Arduino light sensor tutorial we’re going to show the basics of connecting a light sensor (or photoresistor) to the Arduino and reading its input. A photoresistor is a sensor that changes resistance based on the amount of light being delivered to its sensor. In this way we not only detect whether it is […]
