In this chapter we learnt:
Automation is all about devices working on their own without human intervention. Smart street lights that turn on at night, Smart gardening systems that water plants are some examples of automation.
Light Dependent Resistors and the phenomenon of photo-conductivity, where the conductivity of a material depends on the amount of light falling on it
How to read Analog data on the analog pins of the Arduino using the
The miracle of voltage dividers, and how they are used for converting a change in resistance to a change in voltage so that the Arduino can read it
