robot tank ultrasonic sensor

Make an Autonomous Robot Tank with HC-SR04 Sensor

The epitome of robotics is obstacle detection and avoidance. With a simple HC-SR04 sensor, you can detect objects with using ultrasonic waves (sound). In this project, we will use the HC-SR04 sensor and write software for our Robot Tank to avoid obstacles. We’ll make it a bit more complex by utilizing a servo motor to […]

Line Following Robot no programming

How to Build a Robot Line Follower without a Controller

In this tutorial I will show you how to make a simple line follower robot. Normally these type of robots use microcontrollers and complex logic to track and follow line. But today I will be showing you how you can make a simple line follower without a microcontroller. Before we start making the robot, let’s […]

Motor Controller Mobile Robot

Motor Controller Raspberry Pi & Arduino Configurations

If you’re anything like me, then you enjoy building mobile robots. As I’m sure you’re aware, mobile robots are comprised of 5 parts: chassis, motors, controllers, sensors, and power. To cover three of these groups, you’ll need to properly wire the motors to the controllers (motor and master) and then add your power supply. It’s […]

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! […]

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 […]

WeMos WiFi Controlled Robot using L298N

Hello and welcome back to this week’s Learn Robotics tutorial! I’m going to preface this article by saying, man, did I dig myself into a bit of a hole with this one! For those of you on Instagram, I posted a video saying I was going to build and program a Wifi-connected robot using a […]

Program Arduino IR Remote to Control a Mobile Robot

Program Arduino IR Remote to Control a Mobile Robot

If you liked my article on Controlling an Arduino Mobile Robot using a Bluetooth Keyboard, then you’re in for a real treat! This week’s article will be focused on using an Infrared (IR) sensor to control the Arduino Robot using a TV remote. Before we get started, let’s learn about Infrared signals and sensors, and […]

How to Power Your Arduino Mobile Robot

How to Power Your Arduino Mobile Robot

We’ve all gone through it. We’ve built an awesome robot with all sorts of features, but now the time has come to detach it from our computers and run some tests.  You think you’re all set, ready to go, but then you realize, wait… what about power? If you’ve forgotten to add a battery pack into […]

Arduino LCD using Sensor Shield V5

Arduino LCD using Sensor Shield v5

Welcome back to another LR tutorial! In this article, I will show you how to configure your Arduino LCD using Sensor Shield V5. Set aside 30-45 minutes, and you’ll be well on your way to displaying data from your Arduino or Sensors. In my Youth Robotics classes, we use Arduino Mobile Robots. I wanted to include […]
