The previous code did not work as I wanted since:  

-My device generated many entries, even when the user didn't press any buttons.

-My device was sometimes working. as it was not detecting some signals

The inconsistency of the device was a strong indicator that I needed another iteration that changes the flow and interpretation of the information. 

After realizing that I needed to amend the code, I modified it by inserting the values into a string and adding a conditional "if" statement so that it would only generate an entry once a button is pushed. 

Also, I realized that as this is an analytical device, it was more important to visualize the data. To do that, I took advantage of IFTTT, as I registered my device and started 2 applets that would log the responses into individual Excel sheets. To do that, I added the applet and customized it so that it would read the variables I am interested in and indicated the items I wanted in each row.
