Before getting connected with the Arduino software, I learned from peers how to use the wrapping tool to wire up the thin cables to the FSR during the breadboard preparation. I also changed the wire to thicker ones later for the speaker in order to get connected properly.
The sound is clear but it will take a very long time to have the visual part processed.

I followed the instructions on the site and the speaker worked properly.
I spent a little bit more time on this section. The issue is always the tone did not change with the different input from the FSR, and the FSR seemed to be an independent system isolated from the circuit.
I noticed the first two data (200,900) in the mapping method in the sample code is too big for the sensor reading, so I changed the two numbers and got the frequency change finally.
