Code Wrangling at its Best
The “Negative Load” Problem Standard linear regulators, like the ubiquitous LM7805, are designed to be “sinks” of power. They take a higher voltage and drop it down, pushing current out of their output pin to power your circuit. However, they are effectively “one-way valves.” In a modern project—especially one involving motors, large inductors, or external
Electronics is an exciting and rewarding hobby that allows you to build your own circuits and devices. This introduction explains the basics of electricity, including voltage, current, and resistance, and how they work together in electronic circuits. You’ll also learn about Ohm’s Law, which helps you calculate the relationship between these key concepts. Whether you’re a beginner or looking to refresh your knowledge, this guide will give you a solid foundation to explore the world of electronics.
