Section C: Short Answer (Q31 – Q40)
31. List any four fields where robots are used.
Agriculture, Manufacturing, Space, Healthcare.
32. Define a Microcontroller.
A small computer on a single chip with processor, memory, and I/O pins.
33. Why is a smart door with face detection superior to a PIR sensor?
PIR detects any heat (animals); Face detection ensures only humans enter.

Input Unit, Control Unit, and Output Unit.
35. Distinguish between Anode and Cathode.
Anode is Positive (Long leg); Cathode is Negative (Short leg).
36. Function of USB port on Arduino?
To upload code from PC and provide power.
37. Role of IR Sensor in sanitizer dispenser?
To detect the presence of a hand.
38. Why is a resistor used in an LED circuit?
To prevent excessive current from burning the LED.
39. What is the use of PWM pins?
To control actuators like servo motors.
40. Explain “Wait” block function.
Pauses the program for a specific time.

41. Compare Upload Mode and Stage Mode.
Upload: Code saved on board (offline). Stage: Code runs via USB (online).
42. How does a servo motor differ from a standard motor?
Servo rotates to specific angles (0-180°); Standard motor rotates continuously.
