Tired of building the same old Arduino projects like blinking LEDs, temperature monitors, and line-following robots? Now it’s ...

Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides clear results in just seconds. For related tutorials and step-by-step build ...

In this video I've created a device that can notify in real time about events that happen on a website. The project uses NodeMCU board and a buzzer to produce sound as alert. The board is programmed ...

In this video I’m showing how I’ve built a very simple battery backup circuit for my home alarm system. The circuit charges a 12v lead acid battery and in an event of a power loss, it transfers the ...

Abstract: Electric vehicles (EVs) work on electric power supplied by portable energy storage devices such as batteries. This paper proposed a battery charging system with overcharging protection using ...

Abstract: The paper focuses on the development, simulation, and practical implementation of a passive cell balancing methodology for lithium-ion batteries using the Arduino UNO microcontroller unit, ...

This section provides the wiring guide for connecting a 2.8inch TFT display based on ILI9341 to an ESP32 development board. The table below outlines the pin connections for the display and touch ...
