Due to many requests by our user community I’ve put together this handy list of Arduino sensors and modules. There are many, many sensors and the differences and uses of some of them can be very confusing. In this list of Arduino sensors we’ll explain what each one is used for and some quick links […]
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 […]
This update is going to be all about the R2-D2 dome build, specifically the mechanical and electronics portion for automating the pie panels. This was actually one of the most frustrating parts so far. Not because the work was all that hard, but because much of the componentry that is sold flat out does not […]
One of the best features of the Arduino is the ability to control relays. Relays allow a circuit of one voltage or current to be operated by a circuit of a different voltage or current. In the case of an Arduino that operates at either 3.3V or 5V DC, connecting a relay allows us to […]
One the most common questions I get from new visitors to my site and friends of the guild is “I’d like to get started with Arduino, but I don’t even have a clue where to begin? What should I buy?” In this recommendation article I’m going to take the mystery out of it and help […]
In this tutorial we’re going to make an Arduino TV B-Gone and its super simple. If you’re not familiar with a TV B-Gone, it’s a device that uses a small micro-controller to send the IR off codes for every TV make and model on the planet. This is a super handy little device to have […]
In this tutorial we will learn how to setup an IR remote for an Arduino. IR remotes can be used in your projects for all kinds of things. You can use an IR remote to turn on and off a device, LED, relay, or even use it to steer an Arduino robot or automated vehicle. […]
In this basic tutorial we will learn how to setup a keypad on an Arduino. Keypads can be used to control access to things, such as unlocking a door or a safe. Keypads can be added to a myriad of Arduino projects, for learning, or for real world projects. In addition to controlling access to […]
