You can now get samples of real-time speed of a DC motor in MS Excel format using a MATLAB Graphical User Interface (GUI). The variations in motor’s speed are also plotted...

This is a simple function generator that works in the audio frequency range. It can be useful for amplifier testing, experimentation in digital signal processing (DSP) and electronics labs. The author’s...

This project is based on the AEIOU heuristic framework of Design Engineering Approach. Design for Performance, Safety and Reliability is ensured in terms of segregation of the low voltage and the high...

In this project, we are going to make a smart OTP-based locking system as you can see in (Fig. 1). This smart lock can generate a new password every time you...

Due to the outbreak of Covid-19 pandemic, it has become important to check the body temperature of people without any contact with them to prevent spreading of the disease. There are...

Since the outbreak of COVID-19, it has become essential to regularly monitor the human body temperature without coming into contact with the measuring device so that an infected person can be...

Different ICs come with different specifications. Thus, it becomes imperative to apply different hardware configurations and feed all possible inputs for checking different ICs. We need some easy and useful techniques...

Here is an Arduino based social distancing alarm cap meant for Covid-19 pandemic or similar disease outbreak. Maintaining the right gap for social or physical distancing is not always feasible. When...

This project is an FM receiver circuit radio based on Philips TEA5767 digital radio-receiver module. The radio receiver uses I2C interface with Arduino UNO development board. The TEA5767 module offers such...

This article shows you how to build a small radio station at home and share music with others. The station can also be used for making announcements in colleges, industries, hospitals,...
