Summary

This circuit involves an Arduino UNO microcontroller interfacing with various components including two photocells (LDRs), a current sensor, a servo motor, an OLED display, a relay, and a resistor. The circuit is designed to read light levels from the photocells, control a servo motor, display information on an OLED screen, and manage current sensing and relay operations.

Code Documentation

Arduino UNO Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a basic template for the Arduino UNO. The setup() function is where you initialize your components and settings, and the loop() function is where the main logic of your program runs repeatedly.
