Introduction

Exercise 5:

The sensor kit in the lab contains a big number of sensors acting like switches:

rolling ball switch
mercury switch
noise level detector (microphone)
hall sensor (detecting magnetic field)
reed relay (detecting magnetic field)
and many more...

Connect these sensors to the ESP32 and try them with the programs developed in exercise 1-3
