The Story Behind CARE

While researching why people weren't buying air purifiers (beyond just the cost), we stumbled upon something fascinating: most people simply don't care enough about air quality. And that's exactly how CARE was born.

CARE is an…

Rural Primary Health Centers (PHCs) often face staff shortages, making continuous patient monitoring difficult, especially during night shifts. Critical changes in patient vitals such as Heart Rate (HR) and Oxygen Saturation (SpO2) can go unnoticed, leading to delayed medical intervention.

A home is meant to be the safest place for a child, yet falls remain the leading cause of injury in domestic environments. Studies show that nearly 60% of home injuries in children are due to falls, with incidents from heights such as balconies, staircases, and windows being the most severe. Hospital reports indicate…

Most existing home automation systems emphasize remote access rather than intelligent automation. Users are required to manually select modes, configure schedules, or control devices individually through applications. This approach makes the system reactive and increases operational effort. From a system design…

Hi everyone!, my project is a standalone Smart Library Kiosk designed to replace the traditional librarian counter with a self-service system. Built on the Adafruit Memento Development Board (from DigiKey) with an ESP32-S3 chip, it runs independently-currently powered via laptop but easily adaptable to a 3.7V LiPo…

While getting started with electronics, you would like to make some simple circuits like a LED circuit to get acquainted with basic circuit designing concepts. Here is one 555 timer based circuit for you – An LED Flasher Circuit Diagram. Using some common easily available electronic components and an easy to understand schematic, this tutorial will show you how to make an LED glow and…

In this article we decided to make a PID Controller based Heater that can be used to control the temperature of the hot end of the 3D printer or by slightly modifying the device it can control the temperature of a DC Soldering Iron very efficiently, and a little more tweak and you can control a TRIAC and that can control the RPM of an AC motor or an…

Connecting an SD card module to Arduino is way easier than you think. In this guide, we’ll break down the module’s pins and components, show you how to wire it to your Arduino, and get you reading and writing data in no time. Think of it as turning your Arduino into a reliable data logger. We have covered many other interfacing tutorials before that might interest you, such as this 16x2 LCD…

The Smart SMS Alert System using Seeed Studio Xiao ESP32 is one of the compact IoT projects that uses an HC-SR04 ultrasonic sensor to detect nearby movement. The system acts like a motion detector whenever something moves close to the sensor and crosses the set threshold. The ESP32 Seeed Studio module instantly triggers an SMS alert. The ESP32 can send real-time SMS…

In this guide, we will create a simple and precise digital clock using the  Raspberry Pi Pico RTC DS3231 Module through the Arduino IDE. We will use a 16x2 I²C LCD screen to display the information. Since the screen is small, we will write smart code that changes what is shown on the screen. For a few seconds, it will display the time and date, and then switch to show the temperature.…

For microcontrollers, an LED blinking program is equivalent to the “hello world” program. In our previous tutorial, we learned how to get started with STM8S103F3 Development Board and how to set up the IDE and compiler to program our STM8S controllers. We have also learned how to use the standard peripheral libraries, and how to compile and upload the code into our…
