Introduction to Ozobot Blockly 01: Basic Training [Full]

Main Ideas & Lessons

• Goal of the lesson: Learn to use Ozoblockly to create and run block-based programs for an Ozobot.

Required Setup (Implied Prerequisites)

• An Ozobot that is fully charged and calibrated
• The Ozoblockly editor

What You’ll Be Able to Do After the Lesson

• Navigate through Ozoblockly levels
• Connect and program blocks for:
  • Loops
  • Light effects
  • Sound
  • Timing
• Delete unneeded blocks
• Run the program on the Ozobot using Bluetooth

Core Vocabulary

• Code: Instructions written in a programming language.
• Program: A complete set of instructions written in code that a computer executes to achieve a goal.

Ozoblockly Concept

• Ozoblockly is a block-based editor where you select, drag, and connect blocks like puzzle pieces.
• Programs created in Ozoblockly can be sent wirelessly via Bluetooth to Ozobot to run.

Ozoblockly Structure and How to Navigate It

Screen Layout

• Left panel: Where programming blocks are found.
• Right workspace: Where you build the program.

Levels

• Ozoblockly has five levels:
  • Level 1: Beginner-focused.
  • Level 5: Advanced-focused.
• As you move up levels, there are more categories and more advanced blocks.
• This lesson uses Level 2.

Level 2 Block Categories (Five Total)

• Movement
• Light effects
• Timing
• Loops
• Sounds

What Each Category Is For

• Sound blocks: Make Ozobot produce different sounds.
• Movement blocks: Move the bot.
• Light effects blocks: Control Ozobot LED lights.
• Timing blocks: Control the time between blocks/actions.
• Loop blocks: Repeat sequences of actions (full loop details saved for a later lesson).

---

Step-by-Step Methodology / Instructions (Detailed)

A) Practice: Add a Light Effect Block

• Select Light effects.
• Choose Rainbow.
• Drag the Rainbow block into the workspace.
• Practice verifying you can drag-and-drop it correctly.

---

B) Use Workspace Icons (4 Icons)

1. Trash can
2. Duplicate icon (has a plus symbol)
3. Undo icon (arrow turning left / counterclockwise)
4. Redo icon (arrow turning right / clockwise)

How to Use Them

• To select a block:
  • Click the block until it has a white outline (selected state).
• Duplicate:
  • Click the duplicate icon (plus).
  • Result: the block is copied/duplicated.
• Undo:
  • Click the undo icon (left-turning arrow).
  • Result: undoes the last action (example: removes the duplication).
• Redo:
  • Click the redo icon (right-turning arrow).
  • Result: restores the undone action.

---

C) Deleting Blocks (4 Ways)

• Method 1: Drag and drop a block (or group of blocks) into the side panel area.
• Method 2: Drag blocks over the trash icon.
• Method 3: Right-click a block and select Delete block.
• Method 4: Completely clear the workspace:
  • Click the trash icon
  • Select Yes to delete all blocks

Practice: Choose one method to delete all blocks in the workspace.

---

D) Construct a Simple First Movement Program

1. Select the Movement category.
2. Find and drag the move forward block into the workspace.
3. Adjust block settings in Level 2, for example:
   • Move forward distance: 10 steps
   • Speed: medium
4. Find the Move forward (1 step, speed medium) block and drag it in.
5. Change its distance to 10 steps.

---

E) Run the Program on the Ozobot (Bluetooth)

Before running:

• Check the bot icon color:
  • If the bot icon is teal, the bot is connected.

Then:

• Click Run program.
• Observe whether the bot behaves as programmed.

---

F) Expand the Program with Multiple Categories

• After the movement block is set up:
  • Add blocks from light effects, timing, sounds, and optionally loops.
• Connect each new block to the existing block sequence in the workspace.
• Adjust any dropdown/pull-down menu options as needed.
• Run the program and observe Ozobot’s behavior.

---

G) Next Steps / Encouragement

You should now be able to:

• Navigate levels
• Connect and program blocks for loops, light effects, sounds, and timing
• Delete unneeded blocks
• Run programs on Ozobot via Bluetooth

Additional action: continue exploring other levels and building different programs for future lessons.
