L11: General purpose input/output (GPIO) Usage

Welcome to Lecture 11 of the course “Embedded C Programming” by Prof. Nitin Chandrachoodan.
Full Course: https://study.iitm.ac.in/es/course_pages/CS2101.html

Video Overview
This lecture explores key concepts of working with General Purpose Input/Output (GPIO) pins in microcontrollers. Learn about voltage levels, current capacity, and how to safely interface LEDs using current-limiting resistors. Understand motor driving techniques with transistors, effective push button debouncing methods, and the importance of electrostatic discharge (ESD) protection. The session also highlights practical GPIO applications in embedded projects, teaching you how to connect external components reliably while preventing damage to your microcontroller.
