L14: Analog to digital conversion

Welcome to Lecture 14 of the course "Embedded C Programming" by Prof. Nitin Chandrachoodan. Full Course: https://study.iitm.ac.in/es/course_pa... Video Overview This lecture introduces Analog to Digital Conversion (ADC), an essential technique for connecting microcontrollers with real-world signals. Learn how analog inputs from sensors like temperature, light, pressure, and sound are converted into digital data for processing. Understand important concepts including sampling rate, quantization, the Nyquist Criterion, ADC resolution, and full-scale range. The session also covers practical considerations such as channel selection, continuous vs. event-based sampling, and the sample-and-hold mechanism. A hands-on example using Arduino-style code demonstrates reading analog values from a potentiometer, making ADC concepts easy to grasp and apply. 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.
