Hello, I’m working on a light intensity monitoring system using `BeagleBone Black` and a Esp32. I’m interfacing an `LDR` (Light Dependent Resistor) through the `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` properly to the Esp32 and interface it with `BeagleBone Black`?

This is my code below, the issue is am getting no reading from my `Esp32`

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