Help with pyoject

Hi guys

I am new at this , and I am recently starting with my project, i want to do like a wearable wristband device, one of the function i want to try is read body temperature and heartbeat rate , now i want to show that data on my blink app , in simple terms, is it rigth the code below ??

#define BLYNK_PRINT Serial // Comment this out to disable prints and save space
#include <SPI.h>
#include <Ethernet.h>
#include <BlynkSimpleEthernet.h>

char auth[] = “YourAuthToken”;

float heartbeat, Bodytemp ;

void setup()
{
Serial.begin(9600);
Blynk.begin(auth);
}

BLYNK_READ(V0){
Blynk.virtualWrite(V0, heartbeat);
}
BLYNK_READ(V1){
Blynk.virtualWrite(V1,Bodytemp );
}

void loop() {
Blynk.run();
}

thnks !

Hello. Yeap, It is fine. Don’t forget to initialize your variable with some real data. And please use formatting button </>.

Thanks for you quick response !
Also what do you mean with “initialize your varaible with some real data” , and also how could i put this information on the historical graph ?

this :

Ups your right i forgott to put on the code this lines
heartbeat=A0 ;
Bodytem=A1 ;

Thnks for you help, as soon as i get my arduino board, i will practice and will ask for help if i need it !

Thnks again !
