DAY 2 – Breadboard Basics, Series & Parallel Connections | 90 Days Electronics & IoT Course

Welcome to Day-2 of our 90-Day Electronics & IoT Course!
Today we learn how to use a breadboard, how circuits are built, and how Series & Parallel connections change the behavior of LEDs and components.

These concepts are important for all future IoT projects using Arduino, ESP32, sensors, etc.
