The scenario
A solar tracking system uses four LDR sensors to detect sunlight direction on two axes; an Arduino reads the voltage dividers and drives two servos to keep the panel aligned.
What is in this drawing
Read the decisions behind it.
01
Use LDR-resistor voltage dividers on four analog inputs for dual-axis light sensing
02
Power the Arduino and servos from a regulated 5V solar panel supply
03
Drive each axis servo with a dedicated PWM output from the microcontroller
Reuse for small dual-axis solar tracker prototypes, educational Arduino projects, or any light-following panel controller.
