Almost every kitchen has a pressure cooker, but we've all had trouble handling them. It’s too easy to turn on the stove, get distracted by work, TV, or housework, and forget to turn it off. If we miss a whistle count, food gets burned, utensils get spoiled, and there are chances of accidents in the kitchen. But then again, being in the kitchen and manually counting…

Nowadays we can’t even imagine a world without power. Even an intermittent power failure is so inconvenient. As we depend on electricity in many important areas of our life, it is important to take persuasion against power failures and that’s where the inverter plays an important role. There are multiple types of inverters in the market,…

Adding cameras and vision algorithms to your projects and robots might sound cool but sometimes it becomes expensive in terms of both capital and time. When the task at hand is much simpler like obstacle detection, distance measurement, or depth monitoring, ultrasonic sensors are a great alternate to place your bets on. Not only are these sensors fast…

Urban areas are now affected by acoustic disturbances; major Indian cities such as Mumbai, Kolkata, and Delhi rank among the noisiest in the world, driven by dense traffic, construction, festivals, and industrial activity. Extended exposure to these noise levels leads to health issues, including disturbed sleep, increased stress, cardiovascular risk, hearing damage,…

This comprehensive Arduino RFID tutorial teaches you how to interface RFID (Radio Frequency Identification) technology with Arduino microcontrollers using the popular RC522 RFID module. Arduino RFID systems are revolutionizing DIY electronics projects, enabling makers to build professional-grade access control systems, inventory tracking…

By Pratyush GehlotFalls are a leading cause of injury among elderly and mobility-impaired individuals living alone. Traditional monitoring approaches rely on cameras or wearable devices — cameras raise significant privacy concerns in home environments, while wearables depend on the person remembering to wear them and keeping them charged.

Moving through unfamiliar environments is a challenging thing for visually impaired people. We have a lot of solutions, from sticks to obstacle-avoidance handheld devices on the market, to solve their problem. In the DIY world, a lot of makers have built obstacle-avoidance sticks using Ultrasonic sensors, IR sensors or even a PIR sensor and different variations of…

PWM signal generation is a vital tool in every embedded engineers arsenal, they come in very handy for lot of applications like controlling the position of servo motor, switching few power electronic ICs in converters/invertors and even for a simple LED brightness control. In PIC microcontrollers PWM signals can be generated using the Compare, Capture and PWM (CCP) modules…

This comprehensive BMS circuit diagram guide explains the features and working of a 4S 40A Battery Management System (BMS) commonly used with 18650 Li-ion cells. We'll explore the complete BMS circuit for lithium-ion battery applications, including detailed schematics, component analysis, and protection mechanisms. This lithium battery BMS circuit diagram breakdown includes…

Air is a necessity for us human beings, so monitoring it is important. Air quality is monitored in terms of the Air Quality Index(AQI), a single-number scale used to tell how polluted the air is and what health effects it might cause. Particulate Matter is the microscopic solid or liquid which is present in air in the form of dust or smoke. Particulate Matter is the…

In this article, we will be learning about the features and working of the XL4015, which is a 5A 180KHz 36V Buck DC to DC Converter. Here we will desolder all the components from the module, completely reverse engineer the schematic and make the PCB from it, so that we can order the components and make the PCB ourselves. The XL4015 DC-DC buck converter is a versatile…
