How to Interface an LDR with ESP32 and BeagleBone Black for Light Monitoring System?

Hello, I’m working on a light intensity monitoring system using

BeagleBone Black

BeagleBone Black

BeagleBone Black

BeagleBone Black and a Esp32. I’m interfacing an

LDR

LDR

LDR

LDR (Light Dependent Resistor) through the

Esp32

Esp32

Esp32

Esp32 with a 4-digit 7-segment display to show light levels. Could you guys guide me through the setup, For instance how do I connect the

LDR

LDR

LDR

LDR properly to the Esp32 and interface it with

BeagleBone Black

BeagleBone Black?

This is my code below, the issue is am getting no reading from my

     int sensorValue = 0;
     void setup() {
         pinMode(A0, INPUT);
         Serial.begin(9600);
     }
     void loop() {
         sensorValue = analogRead(A0);
         Serial.println(sensorValue);
         delay(1000);
     }

     int sensorValue = 0;
     void setup() {
         pinMode(A0, INPUT);
         Serial.begin(9600);
     }
     void loop() {
         sensorValue = analogRead(A0);
         Serial.println(sensorValue);
         delay(1000);
     }

     int sensorValue = 0;
     void setup() {
         pinMode(A0, INPUT);
         Serial.begin(9600);
     }
     void loop() {
         sensorValue = analogRead(A0);
         Serial.println(sensorValue);
         delay(1000);
     }

     int sensorValue = 0;
     void setup() {
         pinMode(A0, INPUT);
         Serial.begin(9600);
     }
     void loop() {
         sensorValue = analogRead(A0);
         Serial.println(sensorValue);
         delay(1000);
     }
