SENSORS VOL.1

W10 - SENSORS FOR GROUP ASSIGNMENT

The goal I set to myself was to work/ understand a sensor/ set of sensors a day during a month (all the ones that came in a set produced by Elegoo). This process took place during an Independent study summer 2018.

Find the full list here

I did a brief research on each sensor, took some notes, and finally tried to create a quick prototype for each one.
