Functional and Technical Requirements

Two$-$Axis Detection: The sensor must detect light intensity differences to determine the sun's

direction in terms of azimuth $($horizontal angle$)$ and elevation $($vertical angle$)$ relative to the

sensor plane.

Angle Calculation: Implement algorithms to calculate azimuth and elevation angles based on

the processed signals from the light$-$sensitive components.

Signal Processing: Use electronic circuits $($e$.$g$.,$ voltage dividers or amplifiers$)$ to condition and

process signals from the sensor array before feeding them into the microcontroller.

Microcontroller Integration: Utilize an Arduino $($or similar microcontroller$)$ to read analog

signals, process the data, and calculate the sun's position in azimuth and elevation.

Output Display: Present the calculated angles through a serial monitor, LCD display, or visual

outputs $($e$.$g$.,$ LEDs or motor movements$).$

Resolution: The system must achieve an angular resolution of approximately $10-15$ degrees,

sufficient for a coarse sun sensor application.

Calibration: Implement a basic calibration procedure to adjust for sensor variability and ensure

accurate angle calculations. Validate the system's ability to achieve the desired resolution.

Actuators $($Optional$)$: Optionally, integrate actuators $($e$.$g$.,$ servos or motors$)$ to dynamically

adjust the sun sensor$\text{'}$s alignment based on the calculated sun position, simulating solar panel

alignment functionality. I have a circuit system but am having trouble writing a code that can use four photoresistors and an Arduino board to find the required angles.
