The Speaker is connected to pin D8 on the Arduino. It will play at 440Hz for 1000ms(1s).
It is working.
Then I changed to frequency to 800Hz to see the difference:
First I measured the FSR sensor range on my circuit.
It turns out to be between 0-850, so I am going to write down 0-800 under map()
Here is the code to run it.
