Unlike an Arduino board that requires external components to be functional, a Raspberry Pi is a powerhouse by itself right out of the box. It is, after all, a computer. This means that by simply ...
Abstract: This paper presents the design and development of a solar-driven wastewater pumping system aimed at improving energy efficiency and stability in water management applications. The system ...
After a major water leak flooded my home, I realized alerts alone weren’t sufficient—I needed automatic shutoff. This project combines a hacked Gröhe Guard system, an Arduino Nano, an ESP32, and the ...
The relay module used this time is LOW trigger (relay ON when control signal is 0V, relay OFF when 5V (3.5V or higher)). Many relay modules are designed this way. The power supply for the above ...
Hello and welcome back! In this project, we will learn how to make a simple door lock system using RFID technology. This system is mainly built around the Arduino Nano board. For the locking mechanism ...
“M5Stamp PLC Controller with M5StampS3” or just “M5Stack StamPLC” is a programmable logic controller (PLC) based on the StampS3A ESP32-S3 wireless module and offering 8 opto-isolated digital inputs, 4 ...
This Windows-based program, created with Microsoft Visual Basic (VB6), features an intuitive user graphic interface (UGI) and operates seamlessly on the Windows platform. It interfaces with a personal ...
