Change the pitch of a buzzer from the dashboard with a slider.

This tutorial is part of the Nairda learning path. You can build it step by step inside the app, which checks every block you place before letting you move on.

The steps

  1. We add a While loop, which repeats forever.
  2. We declare a frequency called buzzer on pin 9.
  3. We create a number variable called frequency.
  4. Inside the loop we put the buzzer and give it the variable frequency.
  5. On the dashboard we put a slider and give it the variable frequency.

When you finish, the app takes you straight to the next tutorial in the path.
