Based on:
- https://github.com/G6EJD/ESP32_2D_Sun_Tracker (for sun position) https://www.youtube.com/watch?v=R1tFOd0s6uk&t=2s
- https://github.com/ruenahcmohr/EGMK (for motor movement)
-
Uses built in arduino libraries.
-
No photoresistors or accelerometer needed.
-
Tracker results verified at https://www.suncalc.org/
