Digital Systems
What is a Micro:bit?
A small programmable computer used to learn coding and control devices.
What is an algorithm?
A set of step-by-step instructions to complete a task
In MakeCode, what does the “forever” block do?
Repeats instructions continuously while the program runs.
How can the Maqueen Car avoid obstacles?
Using its ultrasonic sensor to detect objects and turn away.
How does coding relate to creating digital solutions?
Coding turns ideas into working systems that solve real problems.
What is the Maqueen robot car?
A programmable robot car that works with a Micro:bit to move, sense, and interact.
How do you code the Maqueen Car?
By using the MakeCode website with block-based programming.
What block would you use to display an image on the Micro:bit?
“Show LEDs” block.
What is the purpose of adding sound or lights to a Maqueen Car program?
To provide feedback, signals, or make it interactive.
Why is testing important in programming the Maqueen Car?
To ensure the car follows instructions and works as planned.
Name two outputs on the Micro:bit.
(An output is a piece of hardware that receives data from a computer or other electronic device and converts it into a form that a human can perceive, such as visual, audio, tactile, or printed information)
LED display and sound output (buzzer or speaker).
What is the difference between hardware and software in this system?
Hardware = Micro:bit/Maqueen Car, Software = MakeCode program.
How can you make the Maqueen Car turn left?
Program the left wheel to stop or move slower than the right wheel.
Give an example of an LED visual students could code.
A smiley face or arrows pointing in the car’s direction.
Give one example of how the Maqueen Car simulates real-world robotics.
It mimics self-driving cars by avoiding obstacles and following programmed routes.
Name two inputs the Micro:bit can use. (Input is the data, signals, or instructions that are provided to a computer or electronic device from an external source, allowing it to receive information and perform actions.)
Buttons (A & B) and sensors (light, ultrasonic, accelerometer).
Why are loops useful in coding the Maqueen Car?
They allow repeated actions, like moving forward multiple times.
What does “Read ultrasonic sensor” block control?
the ultrasonic sensor on the Maqueen
Why would a student program their car to stop after detecting an object?
For safety and accuracy in navigation.
How does team work help in coding projects?
Students can share ideas, divide tasks, and solve coding issues together.
What type of energy powers the Maqueen Car?
Electrical energy from batteries.
Finding and fixing mistakes in code is also known as De ......?
Debugging
What is a condition in coding?
A rule that makes the program do something only if a requirement is met (e.g., if distance < 10 cm, then turn).
How can coding the Maqueen Car help students learn problem-solving skills?
It requires planning, testing, and adjusting algorithms to achieve goals.
How could coding the Maqueen Car prepare students for future careers?
It builds skills in coding, robotics, and systems thinking, which are important in engineering, IT, and automation.
