I Need to explain this code step by step line by line. Could you please write a dot point for each line of code

const int ledPIn=6; int output;

void setup() { pinMode(ledPIn, OUTPUT); // declare the PWM pin used Serial.begin(9600); // start the serial port }

void loop() { float VoltConv; //voltage conversion int ADC_Count; // ADC value counter delay(5); for( int i=0; i<256; i++ ){ ADC_Count= 0; analogWrite(ledPIn, i); delay(10); for( int cnt=0; cnt<10; cnt++ ){ ADC_Count= ADC_Count+analogRead(A0); analogWrite(ledPIn, i); delay(10); } output = ADC_Count/10; VoltConv=output*(5.0/1023.0); Serial.print(i); Serial.print(","); Serial.println(VoltConv); } while (Serial.available()==0){ } }
