IoT Practical Maha Marathon: M4-R5 | Full Syllabus Prep for Jan 2026 Struggling with Arduino code or circuit connections? This O Level M4-R5.1 Practical Marathon is the only class you need to ace your NIELIT practical exam! We cover the complete exam-based practical syllabus, moving from basic LED blinking to complex sensor-based automation projects. In this session, we focus on Real Exam Questions and the exact logic you need to write error-free programs on the NIELIT online software. What This Marathon Covers: Essential Components: Deep dive into Arduino Uno, Breadboard, Jumper Wires, and Resistors. Critical Sensor Interfacing: LDR & PIR: Creating smart lighting and security alarm systems. DHT11 & Ultrasonic: Building temperature monitors and distance measurement tools. LCD (16x2): Displaying real-time sensor data and custom messages. Actuators: Controlling LEDs, Buzzers, and Servo Motors. Coding Strategy: Writing, debugging, and explaining C-sketches in the Arduino IDE. Viva-Voce Special: 50+ most expected questions asked by external examiners. Key Exam Programs Solved: Traffic Light System: Simulating Red, Yellow, and Green transitions with specific delays. Smart Door/Alarm: Using a PIR sensor to detect motion and trigger a buzzer. Fever Detection: Using a DHT11/LM35 to display "Fever" or "No Fever" on an LCD based on temperature. Automatic Night Lamp: Using an LDR to turn an LED on when it's dark and off during the day.
