Separate values in arduino

[jfjlaros]

You could also use a library for text parsing. E.g.,

#include <textparser.h>

void setup() {
  Serial.begin(9600);

  String split = "133,215/365,3/4,2/12,3/4,5/23,52,23";

  TextParser parser1(",");
  char parts[8][8];  // We expect 8 stings with a maximum length of 8.
  parser1.parseLine(split.c_str(), parts);

  for (char const (&part)[8]: parts) {
    TextParser parser2("/");
    int a, b;
    parser2.parseLine(part, a, b);

    Serial.print(a);
    Serial.print(", ");
    Serial.println(b);
  }
}

void loop() {}

Result:

133, 0
215, 365
3, 4
2, 12
3, 4
5, 23
52, 0
23, 0

Thanks for the code, but i have problem, I receive values of zero.

[antoniel1999]

the values are alternated, the first five values are not from a single sensor, but are a value from one sensor and another value from another sensor

@antoniel1999

values of zero.

Show the code you are running and the data you are sending it. The data is expected is it looks in post #1

[antoniel1999]

hello, the values that are enclosed are the ones that I want to obtain in a variable. the remaining values separate them in another variable.

[antoniel1999]

this is the code of the evaluated sensors.

include<BH1750.h>
#include<Wire.h>
BH1750 sensor;
#include<Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_ADXL345_U.h>
int ADXLAddress= 0x53;
int Sensorluz= 0x23;
Adafruit_ADXL345_Unified accel=Adafruit_ADXL345_Unified();
void setup() {
  
Serial.begin(9600);
if(!accel.begin()){
Serial.println("el sensor esta inacvtivo");
while(1);

}

sensor.begin();
}
void loop() {
 
  unsigned int lux = sensor.readLightLevel();


Serial.print ("Lum: ");
Serial.print(lux, DEC);
Serial.println(",");




delay(1000);
sensors_event_t event;
 accel.getEvent (&event);
Serial.print ("Ace: ");
  Serial.print(event.acceleration.x); 
  Serial.println("/");

  delay(2000);
}

this is what is being sent by serial port.

I have added "," at the end of the brightness sensor values
and I have added "/" at the end of the acceleration sensor values

Of those observed values, I only want to obtain the data from the luminosity sensor in a variable, to later give it a use, for example, if it reaches 20 lux write "low luminosity"
do you understand me ?

@antoniel1999

Serial.print ("Lum: ");

@antoniel1999

Serial.print ("Ace: ");

Remove these lines... the receiving code is expecting the values to be sent as in post #1

So just like this...

30,-0.16/11,0.55/ ...

[antoniel1999]

The code worked perfectly for me, thank you very much. Thank you so much.
Sorry one more question, if you could help me.
If I had more data, with more characters, for example

"133,215/36534%45,23/12345%198,32/76*98%

How could I separate these characters into different variables, would it be the same code that you provided me?

Thank you very much indeed for your help and patience.

[red_car]

Yes.same code. You just need to add another else-if statement for the new delimiter %. Just copy the one for /
