POST 13 ● SERIES 1: ELECTRONICS BASICS ● 11 min read How real electronics products are built — and how you can make your own PCB Introduction Every electronic product you own — your phone, your Arduino, your laptop —…
POST 12 ● SERIES 1: ELECTRONICS BASICS ● 13 min read Get the power right first — everything else depends on a stable, clean supply Introduction The power supply is the foundation of every electronic circuit. Get it wrong and…
POST 11 ● SERIES 1: ELECTRONICS BASICS ● 10 min read Breadboard Basics are one of the first skills every electronics beginner should master. A breadboard is a reusable prototyping platform that lets you build circuits by pushing components and…
Reading Circuit Schematics is one of the most important skills every electronics student, engineer, and hobbyist should master. Every electronic device—from a simple LED circuit to a modern smartphone—is designed using schematic diagrams that follow international standards. Introduction A circuit…
Control a 10A motor from a 5mA Arduino pin — this is what transistors do Introduction Your Arduino GPIO pin can source or sink about 40mA maximum. A small DC motor might need 500mA. A relay coil needs 100mA. A…
From a single indicator LED to RGB strips — everything you need to know about light-emitting diodes Introduction The LED is the first component most people connect to a microcontroller — and the first component most people burn out. Connecting…
The one-way valve of electronics — and the foundation of all semiconductor devices Introduction A diode is the simplest semiconductor component: it allows current to flow in one direction only and blocks it in the other. This simple behaviour is…
The component that stores energy, filters noise, and keeps your circuits stable Introduction Every power supply, microcontroller board, amplifier, and virtually every electronics design includes capacitors. They do things resistors cannot: store energy, block DC while passing AC, smooth voltage…
The most fundamental passive component — in every circuit ever built Introduction If there’s one component in every single electronic circuit, it’s the resistor. They limit current to protect LEDs and transistors, create voltage dividers for sensors, set gain in…
Most beginners only learn how to measure battery voltage, but a digital multimeter can also test current, resistance, continuity, diodes, LEDs, capacitance, and even frequency. Understanding these functions will save hours of troubleshooting and help you diagnose electronic circuits confidently.…
