Sound direction detection is a fascinating concept in robotics and automation. It allows a device to "hear" and determine the direction of a sound. This concept has numerous applications, including robot navigation, smart security systems, gaming, and entertainment. Earlier, we showed you how to measure sound in dB using Arduino. In this tutorial, let's learn how to find the direction of sound…

An earthquake is an unpredictable natural disaster that causes damage to lives and property. It happens suddenly and we cannot stop it but we can be alerted from it. In today’s time, there are many technologies which can be used to detect the small shakes and knocks, so that we can take precautions prior to some major vibrations in earth. Here we are using Accelerometer…

Programming has always been fun and it just got a lot better with development platforms like Arduino. Almost every programmer out here would have tried to develop some kind of game using the language that they learning/practising. This helps them to tune their programming skills in a fun yet productive way. I have been a big fan of Arduino ever since I got introduced to it…

There are several ways to program AVR microcontrollers. We are programming it with USBASP v2.0 serial programmer. For demonstration we will use ATmega16 Microcontroller and Atmel Studio. We will test the programmer with a blink sketch.

Below are the steps to burn the code into Atmega ICs using USBASP JTAG and Atmel Studio:

In this tutorial, we are going to implement an Emotion Recognition System or a Facial Expression Recognition System on a Raspberry Pi 4. We are going to apply a pre-trained model to recognize the facial expression of a person from a real-time video stream. The “FER2013” dataset is used to train the model with the help of a VGG-like Convolutional Neural Network (CNN).

I know making a clock sounds a little irrelevant, especially nowadays because we all have smartphones and no one is going to use or look into the clock for time, but it is good when you are doing some work or during the workout. So, I decided to make one Arduino digital clock for my room. While searching for the clock model, I got thousands of designs but most of them were…

Building an Arduino oscilloscope with OLED display is an affordable way for electronics hobbyists and students to visualize electrical waveforms without spending hundreds of dollars on commercial equipment. This comprehensive guide demonstrates how to create a DIY Arduino based oscilloscope using an Arduino Nano oscilloscope platform with a 1.3" OLED screen that accurately…

In industrial and domestic applications, attendance registering is important at each and every moment. Many industries face a lot of problems due to the lack of a proper attendance monitoring system. To overcome this, we must need a tamper-proof, unattended, and fast attendance registering system, and the best way for it is to use a biometrics identification system…

Timer interrupts are crucial in the use of ESP32 timer interrupt programming projects for accurate timing control. If you want something to occur on schedule, ESP32 timer interrupts give you the accuracy required. A timer interrupt is a dedicated interrupt that operates as a high-precision clock, counting and controlling time events with microsecond precision. ESP32'…

The oscilloscope is a must-have test instrument for any electronics engineer. It is used to visualize and observe various signals, usually as a two-dimensional plot with one or more signals plotted against time. They are used in designing and debugging electronic devices to view and compare waveforms, and determine voltage levels, frequency, noise, and other…

An Arduino hourglass project is a fun and educational project that involves creating a digital hourglass timer using an Arduino microcontroller and some simple electronic components. The project combines programming, electronics, and mechanics to create a functional timer that can be used for various purposes.
