Internet of Things Unit 4 – Programming the Arduino: AKTU previous year questions
12 AKTU questions from Unit 4 (Programming the Arduino) asked in 2024–2026, tagged by marks, year and topic. In short: about 26 marks of every paper come from this unit; the most asked topic is Arduino IDE & Coding (6 times); 6 questions came back in a later year. The latest ones are listed below; on the page you can filter them by 2-mark or long questions, topic and repeats.
Unit 4 previous year questions
- What is Arduino IDE? (2 marks, 2026, Arduino IDE & Coding)
- Explain the anatomy of Arduino platform board. (7 marks, 2026, Arduino Platform: Board Anatomy)
- Explain Arduino IDE and the steps involved in programming Arduino for IoT. (7 marks, 2026, Programming Arduino for IoT)
- Explain the structure of an Arduino program with suitable explanation. (7 marks, 2026, Arduino IDE & Coding)
- Name two Arduino board names. (2 marks, 2025, Arduino Platform: Board Anatomy)
- Give 4 names of Arduino library. (2 marks, 2025, Arduino Libraries & Additions)
- Write a C program to interface a DHT11 sensor and an LED with a microcontroller. The LED should turn on only if the temperature exceeds 35°C and the humidity drops below 40% simultaneously. (10 marks, 2025, Programming Arduino for IoT)
- Write an Arduino program to blink an LED connect. However, instead of a fixed blink pattern, make the LED blink using a Fibonacci sequence of delays (e.g., 1s, 1s, 2s, 3s, 5s, 8s, etc.) between on and off states. Reset the sequence after 5 blinks. (10 marks, 2025, Arduino IDE & Coding)
