Fire Engine Bot

Fire Engine Bot

Mimic the siren of a fire engine by programming it into your Buzzer!

What’s in it for you

Fire engines blast a distinctive siren when they’re off to work. Program your buzzer to mimic the sound! If you’ve ever dreamt of mimicking the siren of a fire engine, you’re about to bring it to life!

Tools of the trade

You’ll need a few things in your toolkit to be able to simulate a fire engine siren :
  A laptop or computer
  GizmoBot hardware
  mBlock Version 3 software (ready for download here!)

At the end of the project

Once you’ve completed all the steps, you’ll have :
  programmatically simulated the frequencies of a fire engine siren
  learnt how to create variables in mBlock version 3

Sneak peeks at key steps

Here’s a sneak peek into some key steps in this project, to whet your appetite for programming:
 Generate the sound of the siren by repeating a high-low frequency pattern
  Fix the ratio of amplification time and amplification frequency

Psst… join the project to start from step one!

Hints for programmers

Once you’re done with the project, you’ll want to delete the variables you created because you won’t be needing them in the next set of tasks!

Stuck in a rut

If you’re having a little trouble with any of these steps, all you need to do to unstick yourself is reach out to a project leader. Better yet, plan a brainstorming session with your friends to see what you come up with!

See it in action

At this point, we’re sure you’re curious to see what the finished project looks like. Here’s a glimpse :
