We’ve all seen these sensors and modules kicking around, as part of beginner kits, strapped into prototypes and potentially even in products deployed in the field. Yet as [John Teel] ...

Arduino Battery Capacity Tester is a simple hardware and software project for measuring battery discharge or charge characteristics using an Arduino-compatible microcontroller, an ACS712 current ...

This is a DIY Arduino-based overcurrent relay project that emulates Inverse Definite Minimum Time (IDMT) protection using an Arduino Nano and ACS712 current sensor. Instead of traditional ...

I am leaving this blog to spend more time making things in the workshop and, hopefully, finally mastering FreeCad – amongst other mountains to climb (both intellectual and physical). So this is a ...

Unexpected electricity bills can often be frustrating. This smart energy monitor, built using an ESP32 microcontroller, measures real-time power consumption and predicts upcoming bills with the help ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Abstract: This paper presents an intelligent, energy-efficient lighting system using the ESP8266 microcontroller. The system controls lighting based on ambient light and human presence, using an LDR ...
