L15: Pulse width modulation | generating analog-like signals & control in embedded systems

Welcome to Lecture 15 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 pulse-width modulation (PWM) as an efficient method for digital-to-analog conversion. Learn how PWM uses a high-frequency clock and adjustable duty cycles to create analog-like signals without complex analog circuitry. Understand its practical applications in controlling LED brightness, operating servo motors, and other embedded system tasks. This session provides both conceptual clarity and hands-on insights into implementing PWM using microcontrollers like Arduino and STM32. About IIT Madras' online Bachelor of Science programme IIT Madras offers four-year BS programmes that aim to provide quality education to all, irrespective of age, educational background, or location. The BS programme has multiple levels, which provide flexibility to students to exit at any of these levels. Depending on the courses completed and credits earned, the learner can receive a Foundation Certificate from IITM CODE (Centre for Outreach and Digital Education), Diploma(s) from IIT Madras, or BSc/BS Degrees from IIT Madras.
