Error when asking for numbers on Arduino Uno - c++

Question

my name is Jan, it turns out that when I put a number like 200, it shows me 2 on the console, then a 0 and then another 0
This is my code :
const int ledPin = 3 ;
const int rePin = 2 ;
const int puPin = 1 ;
int pulso = 0;
int input;
void setup() {
// initialize digital pin LED_BUILTIN as an output.
Serial.begin(9600) ;
pinMode(ledPin, OUTPUT);
pinMode(rePin, OUTPUT);
pinMode(puPin, INPUT) ;
}
// the loop function runs over and over again forever
void loop() {
if (Serial.available()) {
char pulso = Serial.read(); //To introduce the pulse
Serial.print("Numero de pulsaciones: ");
Serial.print(pulso);
This is the error : If I put 200
What I want is for an input to appear on the console that requests a certain number of pulses, then when I put them, the number of pulses that I have put appears on the console and then if the pulses are less than 35, for example, give a discharge and a led is activated.

Answer 1

here is the correct code, you just need to configure the serial monitor to send the both NL/CR.
const int ledPin = 3 ;
const int rePin = 2 ;
const int puPin = 1 ;
int pulso = 0;
int input;
bool mensajeRecibido = false;
String mensajeCompleto;
void setup() {
// initialize digital pin LED_BUILTIN as an output.
Serial.begin(9600) ;
pinMode(ledPin, OUTPUT);
pinMode(rePin, OUTPUT);
pinMode(puPin, INPUT) ;
mensajeCompleto.reserve(50); //Se reciben maximo hasta 50 bytes
mensajeCompleto = "";
}
// the loop function runs over and over again forever
void loop() {
if (Serial.available()) {
char byteSerial = Serial.read(); //To introduce the pulse
if(byteSerial == '\n'){
int pulso = mensajeCompleto.toInt();
Serial.print("Numero de pulsaciones: ");
Serial.print(pulso);
mensajeCompleto = "";
}
else{
mensajeCompleto = mensajeCompleto + byteSerial;
}
}
}
