Capteur de tension voltage sensor 25V Raspberry Pi Arduino ESP

Example Arduino :

# include <Wire.h>
int val11;
int val2;

void setup (){
   pinMode (LED1, OUTPUT);
   Serial.begin (9600);
   Serial.println ("Emartee.Com");
   Serial.println ("Voltage:");
   Serial.print ("V");
}
void loop (){
   float temp;
   val11 = analogRead (1);
   temp = val11/4.092;
   val11 = (int) temp ;/ /
   val2 = ((val11% 100) / 10);
   Serial.println (val2);
   delay (1000);
}
