This project is very challenging for me since I don't have experience in coding and building circuit. Through the coding process, I learned the difference between digital signal and analog signal. Analog read/write is used for getting and setting the value of the pin; digital read/write is for digital signal. I successfully accomplished the goal of sensing stuff placed on FSR and tell the different weight by LED signals. If I have a bigger FSR I could use this device to detect package.
