Variables
📦 Variables – Your “Memory Boxes”
What it is: Boxes where you store data for later use.
What it does: Stores information for later use.
Example: Saving a game score or the temperature measured by a sensor and then using it.
👉 They are the robot’s short-term memory.

🧩 Fun Guide to Variables Blocks (Clu-blocks Pro)
🎒 Important! Variables are like backpacks for your robot — they hold numbers, words, lists, or anything you want to remember and use later. You can name them, change them, and check what’s inside!
| # | Block | What it does | Dropdown options | What the options mean |
|---|---|---|---|---|
| 1 | Global variable | Creates a variable that works everywhere | — | You give it a name and choose what type of data it holds |
| 2 | value | Sets or shows the value of a variable | — | You can assign a number, word, list, or anything else here |
| 3 | int (type selector) | Chooses the type of data for the variable | int, float, boolean, string, list, tuple, dictionary, set, byte | – int: whole number– float: decimal– boolean: true/false– string: text– list: group of items– tuple: fixed group– dictionary: key/value pairs– set: unique items– byte: raw data |
| 4 | get type | Checks what type of data is inside a variable | — | Tells you if it’s a number, text, list, etc. — great for debugging |
| 5 | data type int | Sets the data type for a variable | Same as above | You choose what kind of data the variable will hold |
| 6 | Packed Iterator | Groups multiple iterators together | — | Lets you loop through several things at once — like a combo pack |
| 7 | Unpack Iterator | Splits a packed iterator into parts | Iterator, dictionary | – Iterator: goes through items one by one– dictionary: splits key/value pairs |
🧠Quick Tips for Students
- Use variables to store scores, sensor readings, names, or anything you want to reuse.
- Always choose the right data type — it helps your robot know how to handle the info.
- Use get type when something’s not working — it helps you figure out what’s inside.
- Use packed/unpacked iterators for advanced loops — like going through a list of sensors or commands.
