Introduction: Intro&Tools :
This project is using tone() with Arduino to make noise in an easy way.
You will need:
8 wires
1 piezo speaker
1 supersonic sensor
1 breadboard
BE CAREFUL WHEN YOU ARE USING THE PIEZO SPEAKER, IT IS FRAGILE!!!!!!!!!!!!!!
Step 1: Code
Step 2: Try It!
connect the breadboard to your computer
you can try to get close to the supersonic sensor, it will make some noise when you get to a specific distance
