Controller
The central brain of Sunbeamer. It is programmed with Arduino language. Controls the motors, reads the compass and clock. Provides very basic web interface for users. We're using ESP-32.
Motors
Two motors are needed to turn the mirror vertically and horizontally. Both servo motors and stepper motors can do the job. We'll be exploring both options.
Compass
Tells the controller how Sunbeamer is oriented.
Clock
To get the information where the Sun is at the moment, heliostat must know the time. This is what Clock module is used for.
