Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes an Arduino UNO microcontroller, a resistor, a photocell (LDR), and a 0.96" OLED display. The circuit is designed to read light intensity using the photocell and display the data on the OLED screen. The Arduino UNO serves as the central controller, interfacing with the other components.

Photocell (LDR)

• pin 0: Connected to pin2 of the Resistor and A0 of the Arduino UNO.
• pin 1: Connected to VDD of the 0.96" OLED and 5V of the Arduino UNO.

0.96" OLED

• GND: Connected to GND of the Arduino UNO.
• VDD: Connected to pin 1 of the Photocell (LDR) and 5V of the Arduino UNO.
• SCK: Connected to A4 of the Arduino UNO.

Code

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 used to initialize any settings, and the loop() function contains the main code that runs repeatedly. You can add your specific logic to read the photocell and display the data on the OLED screen within these functions.
