Hi, I'm Electro — an electronics hobbyist and maker documenting hands-on DIY builds with Arduino, ESP32, and IoT projects. Every guide on this blog is based on projects I've actually built, wired, and debugged myself — including the mistakes along the way. My goal is simple: clear, honest, step-by-step tutorials that actually work, without the fluff.
Ohm’s law states that the current I flowing in a circuit is directly proportional to the applied voltage V and inversely proportional to the resistance R, provided the
temperature remains constant. Thus,
