An electronics enthusiast recently shared an impressive project called Tiny Battle Bots, inspired by the popular BattleBots game show. This creative endeavor combines 3D printing and custom PCB design to produce compact, soccer-playing robots. At the heart of the project is the ESP8266 microcontroller, which enables wireless control for precise movement and gameplay…

This line follower robot with Arduino project example illustrates professional Arduino robotics project ideas through learning by doing. Our complete block diagram of the line follower robot with  Arduino UNO, the approach begins with thoroughly explaining the hardware connections and then explaining the logic behind the software. The complete Arduino…

In this project, we will build a remote-controlled Arduino Air-Boat that can be controlled wirelessly using the 433 MHz RF Radio Modules. We will control this boat using a homemade remote control by building our own 433 MHz transmitter and a receiver module. In the case of remote-controlled devices or communication between two devices, we have a lot of options like IR,…

According to the latest data from the National Crime Records Bureau (NCRB), in 2022, India saw 7,435 deaths due to fire accidents. Even though there are a lot of precautions taken for Fire accidents, these natural/man-made disasters do occur now and then. In the event of a fire breakout, to rescue people and to put out the fire, we are forced to use human resources…

If you are planning on building a robot with DC motors then you will eventually learn that you need to control both the speed and direction of the motor if you want it to move it in a certain direction. And one of the best ways to do it is by using a L293D motor driver IC, because it's cheap, easy to use and with a bit of PWM support it can control both speed and…

Line follower Robot (LFR) is a machine that follows a line, it may be a black line or a white line. The line following bot is beginner-friendly and interesting to understand and build. While Line follower bots are popular and common to be built with Arduino or other microcontrollers, let’s try to build the same without a microcontroller and actually understand the logic…

In a present-day scenario, we are all so busy with our work that we don't have the time for cleaning our house properly. Constructing an Arduino based smart vacuum cleaner robot project has never been easier, affordable and convenient. The solution to the problem is very simple: creating your own automatic floor cleaning robot using Arduino offers a practical DIY…

When developing robotic projects, motors are one of the most important parts of the whole project and there is always a need for multiple motors. But GPIO pins of the Microcontroller boards don’t allow you to draw the amount of current required for a motor. That’s why the motor driver ICs are used. You can build a motor driver circuit by using some electronic components or…

A Raspberry Pi HAT is an add-on board for Raspberry Pi with the same dimensions as Pi. It can directly fit on the top of Raspberry Pi and doesn’t require any further connections. There are many Raspberry Pi HATs available in the market. In this tutorial, we are going to build a Raspberry Pi Motor Driver HAT to drive DC and Stepper motors. This Motor Driver HAT consists of an…

DC motors are the most widely used motors. These motors can be found almost everywhere from small projects to advanced robotics. We previously interfaced DC Motor with many other microcontrollers like Arduino, Raspberry pi and used it in many robotic projects. Today we learn to control DC motor with AVR Microcontroller Atmega16. But before going ahead let’s know more about…
