Y9 - Part 1: Arduino Component Study Guide & Prompting Basics

Which component acts as the small computer that runs uploaded code and connects to a PC via USB?

• Standard servo motor

• I2C LCD screen module

• HC-SR04 ultrasonic unit

• Arduino Uno controller board

What is the primary role of the HC-SR04 ultrasonic sensor in a project?

• Spin a shaft continuously at speed

• Store programs for offline use

• Measure distance using sound echoes

• Display text using liquid crystals

Which statement correctly describes how LEDs should be wired on an Arduino?

• Use a capacitor across leads

• Use a 220 ohm series resistor

• Connect directly to 5V power

• Place two LEDs in parallel only

What does the Echo pin on the HC-SR04 sensor do during a reading?

• Selects between two modes

• Supplies constant 5 volt power

• Sends the initial trigger pulse

• Receives the reflected sound pulse

What happens to an LED when the Arduino outputs a HIGH signal to its pin?

• The LED turns on and emits light

• The LED turns off immediately

• The LED flashes random colors

• The LED changes to buzzer mode

Which output device creates sound when the Arduino toggles its pin on and off?

• USB interface port

• Buzzer component device

• I2C LCD module

• Ultrasonic transducer

What makes the I2C LCD screen easy to wire compared to other displays?

• It requires eight parallel pins

• It shares the ultrasonic pins

• It uses two data pins plus power

• It needs no library to program

What is the main purpose of a Pin Map when prompting an AI for Arduino code?

• Reduce the need for resistors on LEDs

• Increase the speed of the processor

• Test sensor accuracy before wiring

• Tell the code which pins each part uses

If your sensor is wired to pins 12 and 13 but the AI generates code for pins 7 and 8, what is the likely outcome?

• The LED brightness will increase

• The device will run but slower

• The code will auto-detect pins used

• The code will fail to work correctly

In the prompt recipe, what does 'Describe the Required Logic' ask you to provide?

• A list of spare parts and tools

• The history of Arduino microcontrollers

• Step-by-step actions the code should perform

• A paragraph about display brightness
