Turtle Scanner

Setting up your project

This project uses an microturtle Extension. You'll need to add it to your project to make it work.

• create a new project
• click on the gearwheel menu and click Extensions
• select the microturtle extension

After the project reloads, you should see the turtle category in the blocks.

Code

The turtle scans the display over and over again.

turtle.setPosition(0, 0)
turtle.turnRight()
turtle.setSpeed(20)
basic.forever(() => {
    turtle.forward(4)
    turtle.turnRight()
    turtle.forward(1)
    turtle.turnRight()
    turtle.forward(4)
    turtle.turnLeft()
    turtle.forward(1)
    turtle.turnLeft()
})
