Bet! Here’s your clean notes version with no lines, ready to copy straight into Knowt or anywhere else:

Polygonal Abstract Design

Advantages

• No syntax — no typing instructions needed

• Represents programming elements easily

• No formatting required, drag and drop

• Easy to learn

• Visual

• Fast

Disadvantages

• No text-based coding included, beginners only

• Simple instructions only — can’t create your own instructions

MakeCode Input and Acceleration Blocks

• button A is pressed?

• acceleration mg

• acceleration x

• forever

MakeCode Loop Blocks

• repeat [x] number of times

• do while false / true do

Variables

• A variable is a value that can change

• Like a box that holds info you can update anytime

• Example: score can start at 0 and change as game progresses

• Use blocks: set [variable] to [value], change [variable] by [value]

Micro:bit Labeled Diagram (Front View)

Labels:

• LED Display: 5x5 grid of LEDs used to show numbers, icons, and text

• Button A & Button B: Physical buttons you can press to input commands

• Pins (P0, P1, P2): Input/output pins to connect sensors or other devices

• Reset Button: Restarts the micro:bit

• Micro USB Port: Connects to a computer for power and programming

New Concepts Added

Algorithm

• An algorithm is a step-by-step set of instructions used to solve a problem or complete a task

Economies

• Linear economy: We take resources, make products, use them, and throw them away

• Circular economy: We keep using and reusing materials to reduce waste and protect the environment

Examples of AI

1. Siri or Google Assistant – AI that answers your questions and follows voice commands

2. Netflix recommendations – AI suggests shows you might like based on what you’ve watched

3. Self-driving cars – AI helps the car "see" the road and make driving decisions
