Halloween is near, and I’ve had a lot of requests for another Arduino Halloween Project. If you didn’t get a chance to look at my Animated Skull project, definitely check that one out too! For this activity, we’re going to be making Twitching Eyeball Pumpkins. (Shoutout to 68percentwater for this idea!) The goal is to […]
Halloween is quickly approaching. And, what better way to learn robotics than to make an animated skull using Arduino. In this tutorial, I will walk you through how to make a moving and glowing skull to put on your doorstep and scare trick-or-treaters! Here’s what it’ll look like when it’s finished! Ready to build yours? Scare Trick-or-Treaters […]
Learn to program pan-tilt servos using buttons and potentiometers. Full tutorial including wiring diagrams and code samples.
In this tutorial, I’ll show you how to assemble pan/tilt for Arduino servos. This should take you about 20 minutes to fully assemble. In my next tutorial, I’ll show you how to program these servos using Arduino for manual control using potentiometers & buttons. How to Assemble Pan/Tilt for Arduino Servos To start off, you’ll […]
Cool Arduino Projects is a new tutorial series we’ve started on the Learn Robotics blog. The goal is to show you how to create application-based projects using Arduino. If you’re a teacher looking for a STEM project, you can use the full lesson plans in your class. The Application: Ties to Math & Comp […]
When you’re first learning Arduino, most people recommend using the Arduino Uno. And, I too, agree that the Arduino Uno is a great controller to use when you’re starting. Once you have a better grasp of how to set up your circuit and begin to dabble into your projects, you may want to expand your knowledge […]
I’ve had a bit of an Internet of Things (IoT) bug the last couple of weeks. For those of you who are new to the blog, welcome! I’m glad you’re following along with my tutorials. Hopefully, you’re making some cool things! Before we dive right into prototyping and code, and whatnot, I wanted to provide […]
I had this neat idea to control a mobile robot using Node-RED. Before creating the Node-RED dashboard for a robot, I wanted to create something simple as a proof of concept. And, in this article, I’m going to share with you how to configure Node-RED with the Wemos D1 Mini using MQTT. I recommend you […]
Arduino projects are becoming more common these days. If you want to make your own devices, dabble in the world of electronics, or improve your coding skills, Arduino is a good place to start. We’ve scoured the internet to find you our top picks for Arduino Kits. Best Arduino Starter Kits Looking for your first […]
Learn how to use dweet.io and freeboard.io to create real-time dashboards for your IoT projects.
Last week, we looked at fetching data from dweet.io using Python. Then we found a way to retrieve data and store it in a local database. In this tutorial, we’re going to create our own electronic device and publish data to dweet.io. Hardware for this project You will need a WiFi-compatible controller to complete this […]
In the last tutorial, we fetched data from connected devices published on dweet.io. Now, we’re going to create a Python script to grab device data for a database. If you haven’t read the previous tutorial, I recommend completing that before attempting this one. This tutorial is most suitable for those who are familiar with SQL databases and […]
For this tutorial, I’m going to walk you through the process of fetching data from dweet.io using Python. Fetch Data from dweet.io using Python dweet.io is a website that is similar to twitter but for connected devices. You can access sensor readings through a dweet.io URL in a JSON format. We will use this website […]
A few weeks ago, I was asked to review a new electronics kit by the startup, MakeXchange, out of Chicago, IL. In this article, I’m going to speak to the benefits and drawbacks of this kit, as well as who it’s for, and where you can get yours. Let’s dive into this MakeXchange Inventing with […]
Blinking LED’s is a staple example of beginner Arduino programming. In this tutorial, we’re going to step it up a notch and use both arrays and the random() method to determine which LED to turn on and off for a duration. Materials for Random LED project Arduino Uno (or similar controller) Breadboard 4X LED’s in […]
