Exploring Basic Electronics: Soldering, Sensors, and Circuits on Robo-week Day 3

Welcome to Day 3 of Robo-week! Today’s session features hands-on learning in electronics, focusing on soldering techniques and the fundamentals of voltage regulation. Participants will explore light-dependent resistors (LDRs), the LM324 comparator IC, and the use of transistors as drivers. We will build practical projects including a traffic light circuit and a line-following circuit without microcontrollers. By the end of the day, attendees will understand voltage regulation, rectifiers, and how to use comparators effectively in simple electronic circuits.
