Coding mission

Think about how a fan moves. Code the fan to start spinning when you press the button.

Blocks and their jobs

  • DC Motor BlockFan blades
  • Touch Sensor BlockFan button

Let's think

Think about machines around us that work when you push a button, and talk about how they work.

Blender
Power button
Elevator buttons
Show the solution

While the touch sensor block isn’t pressed, the DC motor block stays still. When you press the button once, the motor turns counterclockwise five times and stops.
