Why this subject?	Contents
Embedded systems are modularly integrated small digital processor or controller based systems along with specialized electronic circuits for interfacing with other embedded systems, sensors, communication lines, etc. The objective of this laboratory course is to provide students with an understanding of developing such modular systems. We would be using the standard reference of an 8-bit microcontroller based open-source embedded system development board to explain the various concepts through laboratory exercises and a capstone project. Text books: [1]. M. Banzi, M. Shiloh, Make: Getting Started with Arduino, 3 Ed, Make, 2015. [2]. D. Wilcher, Make: Basic Arduino Projects, Make, 2014. [3]. K. Karvinen, T. Karvinen, Make: Getting Started with Sensors, Make, 2014. [4]. C. Pfister, Getting Started with the Internet of Things, O'Reilly, 2011. Measure of Outcome: A student undertaking this subject would be graded based on perfromance in all of the following: (1) Regular participation in class activity. (2) Timely submission of all experiments in class. (3) Development of a capstone project. (4) Appear for the viva voce exam. Code of Conduct: * Experiments are to be performed individually. * At the start of a day, issue a kit-box and sign on the issue register. * Do not issue the same box every day. * Before issuing check the contents of the box as mentioned on it. * If you find some component in your kit malfunctioning, bring it to the note of the TA immediately. * Return the box with all components in it at the end of the lab. * Once an experiment is completed, get yourself evaluated by any one of the TA. * Move from one experiment to the next as you complete.

Pedagogical Objectives

The aim is to teach students fundamentals of Embedded System Design. It would be beneficial to students opting for specialization in microcontroller based designs, IoT, sensor networks, communication system design, etc., who can use the gained skills in order to develop newer technological innovations and regularize their high-throughput translation and usage.

On completion of the course, a student would be able to:
1. Explain and discuss the engineering principles of microcontroller based embedded syetem design.
2. Demonstrate the ability of interfacing sensors to microcontrollers and analyzing signals in digital domain using their foundations of linear algebra and signal processing.
3. Design and develop new techniques for improved interfacing and inter device communication and connection towards internet of things.
