Why Adding a Base‑Emitter Resistor Is Crucial for Reliable Transistor Switches

The article explains the essential role of a base‑emitter (BE) resistor in transistor circuits—providing a stable bias, protecting against ESD, speeding up turn‑off, reducing noise sensitivity—and offers practical guidelines for selecting its value and integrating it into common embedded designs.

How a Simple Switch Becomes a Powerful CPU: From Transistors to Logic Gates

This article explains how a single transistor acts as a switch, how combining AND, OR, and NOT gates yields logical completeness, how binary addition is built from these gates, and how registers, memory, instruction sets, and clock signals together form a functional CPU.
