If you’re starting with ESP32, IoT, Arduino, embedded systems, or practical electronics, understanding electronic components is essential.
In this video, we break down the **essential electronic components and hardware building blocks** you’ll encounter in real-world IoT and embedded circuits — what they do, how they work, their important characteristics, and where they are actually used.
You’ll learn about:
🔹 Breadboard & Jumper Wires
🔹 LED
🔹 Resistor
🔹 Potentiometer
🔹 Capacitor — Ceramic & Electrolytic
🔹 Inductor
🔹 Ferrite Bead
🔹 Diode
🔹 Schottky Diode
🔹 Zener Diode
🔹 TVS & ESD Protection
🔹 NPN Transistor
🔹 PNP Transistor
🔹 N-Channel MOSFET
🔹 P-Channel MOSFET
🔹 Optocoupler
🔹 Linear Voltage Regulator & LDO
🔹 Logic Level Converter
🔹 Operational Amplifier
🔹 7-Segment Display
🔹 LCD Display
But this isn’t just a list of components.
You’ll also see how these components fit into a practical **ESP32 / IoT system** — from sensors and inputs to signal conditioning, switching, power regulation, protection, communication, and displays.
By the end, the goal is to stop seeing an IoT circuit as a collection of random components and start understanding **why each component is there and what job it performs.**
The ESP32 is more than a development board. It can become the controller at the center of a complete system that you can design and build.
