A unique experimental clock created by soiboi soft is gaining attention for its unusual way of telling time. While it may look like a fully air powered system, the design actually combines pneumatic logic with electronic control. Instead of relying only on circuits and chips, the clock uses air pressure to form its display, while electronics handle precise timing and control, making it a…

Absence of light is what causes darkness, and we can automatically detect darkness or intensity of light using a Light Dependent Resistor (LDR). The circuit can be integrated with other electronics circuits or projects to control lights of a small bulb for automating lighting of something as large as whole city’s street lights. In this project, we will be making a…

In this tutorial, we will learn about Real Time Clock (RTC) and its interfacing with the ESP32 and OLED display.

We will use the DS3231 RTC module to keep track of the correct time and display it on the SPI OLED by using ESP32 as our microcontroller. ESP32 is more than a microcontroller. It has a Wi-Fi and Bluetooth chip inside it and 39 GPIO pins.…

Thermostat is formed by summing two Greek terms thermo and statos, thermos means heat and statos means stationary, standing, or fixed. Thermostat is used to control the devices or home appliances according to the temperature, like turn on/off air conditioner, room heaters etc. Common applications of thermostat are to maintain room temperature in centralized heating…

Sometimes we face a common problem when making any project related to battery or power supply - we don’t know about battery is charged or discharged. To test battery there is one common method which is using voltmeter that is available in the Multimeters. But here we have developed this battery monitor circuit to test the battery charging status. In…
