Master the M4-R5.1 Practical: Internet of Things (IoT) | NIELIT O Level

Welcome to this comprehensive practical session for the NIELIT O Level M4-R5.1 (Internet of Things) module. This video is specifically designed to help students preparing for the January 2026 examination cycle to master the hands-on components of the IoT syllabus.

In this class, we dive deep into the essential practical exercises, ranging from basic sensor interfacing to complex Arduino/ESP8266 programming.

What You Will Learn:
Hardware Interfacing: Setting up breadboards, LEDs, Buzzers, and LDRs.

Sensors & Actuators: Practical implementation of DHT11 (Temperature & Humidity), Ultrasonic sensors, and PIR sensors.

Coding Fundamentals: Writing and debugging "C" sketches in the Arduino IDE for IoT applications.

Connectivity: Understanding how to interface sensors with microcontrollers.

Exam Tips: Common practical viva questions and troubleshooting techniques for the January 2026 lab exam.

Key Topics Covered:
Introduction to Arduino IDE & Board Setup.

Digital vs. Analog I/O Operations.

Interfacing Sensors (LDR, DHT11, Ultrasonic).

Display Modules (LCD 16x2 Interfacing).

Solved Practical Lab Exercises from previous years.
