Intro to Physical Computing

Lab: Tone Output

Connect Sensor and Speaker

I adjust the threshold range from 200-900 to 10-800, so that my sensor is able to capture my movement.



 A More Complex Example

Instead of put the toning code inside of “set up”, I write it inside of “loop” so it plays constantly.



A Musical Instrument

I adjust the threshold from 10 to 100 to filter the noise.
The C3 in note is too low to be play on speaker, so I adjust the last sensor to C8. It plays a high pitch beep sound, along with first sensor’s A5 and second sensor’s E6.
