Arduino Python Communication

Communication Between Arduino & Python

Recently I started learning Python, and I was amazed by the simplicity and capabilities. So, I thought let’s connect it to Arduino, and see what I can do with it. Communication between Arduino and Python isn’t a new concept, There are many modules available for Python that help in the process. In this tutorial, I’m […]

Arduino L298N motor code

How to Program the L298N with Arduino

If you’ve ever tried to build a mobile robot, then you’ll need to learn how to program motor controllers. In our Beginner Bots tutorials, we use the L298N motor controller with the Arduino Uno to drive four motors. You can pick up a Smart Robot Car and follow along with this article if you’d like! […]

Smart Robot Arm Tutorial Arduino

Simple & Smart Robotic Arm Using Arduino

In this tutorial, I will share with you how to make a smart robotic arm. You can control this arm using a “Master” arm using potentiometers. The “Slave” arm is comprised of servos and will run off of the potentiometer readings. This will mimic manual movements. Along with this feature, the prototype is also smart […]

getting started with NodeMCU

Getting Started With NodeMCU (ESP8266) Using Arduino IDE

In this article, I will be sharing with you… how to get started with NodeMCU ESP8266 development board how you can program it easily using good old Arduino IDE and take your project to next level with WiFi connectivity. Before we get started, I assume that you have a basic knowledge about Arduino and its […]

Merge Two Arduino Sketches

Merge Two Arduino Sketches Together

Do you have multiple Arduino sketches that you’d like to merge into one? Then you’ll want to stay tuned for this tutorial! I had a question come in this week about combining Arduino sketches. And for those of you who have never done this, you might be very pleased to know this is actually pretty […]

Arduino Halloween Project

Arduino Halloween Project: Twitching Eyeball Pumpkin

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 […]

Animated Skull using Arduino Halloween Project

Animated Skull using Arduino Halloween Project

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 […]

how to assemble pan/tilt for Arduino servos

How to Assemble Pan/Tilt for Arduino Servos

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 Arduino Dice Simulation

Cool Arduino Projects: Arduino Dice Simulation

  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 […]

configure Node-RED and Wemos D1 Mini using MQTT

Configure Node-RED & Wemos D1 Mini

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 […]

Random LEDs with Arduino Uno

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 […]

Intermediate Arduino Robot Projects

Over the past five weeks, you’ve been following along with the Beginner Bots series where we walked through the process of building, wiring, and programming our robots to move, follow lines, and avoid objects. If you’ve enjoyed these tutorials, my fee to keep them free is simple: click the 5-STAR REVIEW button at the bottom […]

mobile robots ultrasonic sensor

How to Build a Mobile Robot Using Arduino | Part 5

I see you! Well, at least the robots will after this lesson! Last lesson we learned about infrared IR sensors, IF statements, and line following/avoiding. This week, we are learning about Ultrasonic Sensors, FOR loops, and object avoidance. Robot using Arduino and Ultrasonic Sensors – Objectives & Materials Each week I will provide you with […]

Visualize Data using the Arduino Serial Monitor & Plotter

Today’s post is going to be a bit shorter because I’ve created a video walk-through that explains the how-to’s. So if you’re a visual learner, you’re in luck! Visualize Data using the Arduino IDE I’ve been working on projects lately where data visualization is very important. So, as curious as I am, I wanted to […]
