How to control solar light chasing by single chip microcomputer

The timer of single-chip microcomputer can follow the light at that time, because the position and time of the sun are constant, and the position of the sun is fixed at the same place and time every day. The single chip microcomputer controls the motor to drive the actuator to rotate at a corresponding angle every 30 minutes or 1 hour. The height angle changes with the seasons, so it doesn't need to be adjusted every day. If it is adjusted, it can be done manually. The automatic adjustment mechanism in two directions at the same time is complicated and expensive.
