A robotic arm is one of the most popular projects that almost every electronics enthusiast tries to build at least once in their life. Robotic arms are fascinating projects because they can be built for many practical applications, such as pick-and-place operations, component assembly, repetitive tasks, and even creating intelligent systems like the robotic arm “…

Fossil fuels have been consumed rapidly over recent decades, and their availability is decreasing. Because of this, there is a growing focus on renewable energy sources. Solar energy is one of the most reliable options since sunlight is available throughout the day. Solar panels absorb solar radiation and transform it into electrical energy. The intensity and angle…

Mobile phone is a revolutionary invention of the century. It was primarily designed for making and receiving calls & text messages, but it has become the whole world after the Smart phone comes into the picture. In this project we are building a home automation system, where one can control the home appliances, using the simple GSM based phone, just by sending SMS…

In our previous tutorials, we have learned about How to interface GPS module with Computer, how to build a Arduino GPS Clock and how to Track vehicle using GSM and GPS.  Here in this project, we are going to build a Arduino based vehicle accident alert system using GPS, GSM and accelerometer. Accelerometer detects the sudden change in the axes of vehicle and GSM…

The PCA9306 module is a bidirectional voltage-level translator made for use with I2C bus systems. It allows devices that work at different voltage levels to communicate reliably. Older designs used separate MOSFET circuits for voltage shifting, but the PCA9306 combines all that functionality into one chip, making it more dependable and consistent. The device…

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…

DC motor is the most used motor in Robotics and electronics projects. For controlling the speed of DC motor we have various methods, like the speed can be automatically controlled based on temperature but in this project PWM method will be used to control the speed of DC motor. Here in this Arduino Motor Speed Control project, the speed can be controlled by…

An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention. The “automatic toll gate system project” demonstrates how simple sensors and a microcontroller can automate a real-life process like toll collection, making it an ideal project for school students and anyone just starting in the field of…

CNC Machines are Computerized Numerical Control Machines which are used to draw anything or design any mechanical part according to the design program fed into their controller unit. Controller unit can be either computer or microcontroller. CNC machines have stepper and servo motors to draw the design as per the fed program.

After researching on…

Have you ever wanted to build your own IoT-based Weather Monitoring Station? Imagine monitoring real-time temperature, humidity levels, atmospheric pressure, rainfall detection, air quality index (AQI), and more—right from your local network. With the power of the Arduino UNO R4 WiFi, you can create a dynamic weather dashboard web page that displays all your environmental data in real-time…

The pH scale is used to measure the acidity and basicity of a liquid. It can have readings ranging from 0-14, where 0 shows the most acidic liquid and 14 shows the most basic liquid. 7 pH is for neutral substances that are neither acidic nor basic. Now, pH plays a very important role in our lives, and it is used in various applications. For example, it can be used in a…

Li-Fi (Light Fidelity) is an advanced technology that allows transferring data using optical communication, such as visible light. Li-Fi data can travel through the light and then be interpreted on the receiver side using any light-sensitive device, like an LDR or a photodiode. Li-Fi communication can be 100 times faster than Wi-Fi. In this comprehensive guide, we'll…
