How to Start with Raspberry Pi (for Beginners)

Lately we have been creating projects that use the Raspberry Pi computer. Unlike Arduino, the Raspberry Pi is a computer, so it won’t work without installing the Operating System. In this article, you’ll learn how to start with Raspberry Pi by creating a bootable Raspbian SD card. What is Raspberry Pi? To start, the Raspberry […]

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 […]

How to Record a Push Button Sequence with Arduino

There are many feats of learning Arduino. Besides plugging in your board and downloading the “blink” sketch, it’s important to learn more about digital inputs. The epitome of digital inputs is push buttons. Push buttons are used for a variety of applications to trigger events. In this tutorial, we’re going to explore how to record […]

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 […]

Video Streaming Raspberry Pi Robot & Camera

Have you ever wanted to build a robot that you could drive around from anywhere? In this new “Raspberry Pi FPV” tutorial series, you will learn how to build your own Raspberry Pi robot car and create a First Person View (FPV) driving experience. The first step is to configure video streaming on the Raspberry […]

Arduino Bluetooth Car Tutorial

Arduino Bluetooth Car (Smartphone Controlled)

In the previous tutorial, I showed you how to use a BLE module to control an LED. For this tutorial, we will expand upon that knowledge to create an Arduino Bluetooth Car that can be controlled using a Smartphone. You can pick up an Arduino Robot kit or source all the materials separately to build […]

Arduino Bluetooth Low Energy BLE Tutorial

Bluetooth Low Energy (BLE) Tutorial for Arduino

I am back again with a simple electronics tutorial for beginners. In this post, I will show you how to get started with the Bluetooth Low Energy (BLE) 4.0 module to control LEDs. This project can be adapted to also control relays or robots. BLE is not like normal HC05/06 modules, because it works on […]

Raspberry Pi Node-RED tutorial

Raspberry Pi Node-RED Programming Tutorial

The Raspberry Pi is a single-board linux computer that has exposed General Purpose Inputs and Outputs (GPIO). In this tutorial, I’m going to show you how to program the Raspberry Pi to control an LED using Node-RED. Then, we will create a dashboard UI to control the LED from any web browser. You will need […]

Home Automation using Arduino and WiFi

Home automation is a trending topic these days so I wanted to share with you a new project. We are going to control AC appliances over the internet using an Android phone from anywhere around the world. I used an ESP8266 development board as the main controller. Here  we will be using RemoteMe services. If […]

Control NodeMCU using a Web Page

Control Devices using a Web Browser (NodeMCU)

In this post, I will show you how to connect your NodeMCU or ESP8266 development board to the Internet, and control devices using a web browser. You can use it for a number of projects like, automation, controlling robots over a long distance, and much more. Before you get started checkout the previous article on […]
