Wiring temperature sensor onto board.

  • Coding process:

I downloaded library codes and tested the temperature sensor based on the online tutorial. (

First I planned my pseudocode with the help of Professor Brockmeyer.


Based on the plan, I transferred the algorithm into actual codes. I did not change the library codes for reading temperature.
