Need Help With My Project
1

Hi guys, first congrats on a great platform.
I am only a couple of days old here, and have a small project running, monitoring the pool temperature and changing lights depending on the temp.
Now, in the original implementation, before the IOT version, I had the lights to get on for a sec, then off and on and so on. This was done with a simple delay and a loop turning the outputs of the arduino on and off. Now when I use Blynk, the delay causes disconnects and cannot be used. Tried to play a bit with timers but no cigar. The code works (turns on and changes colors) as well provides data with no issues besides the flashing.
I hope that you can tell me how to fix that, I guess its a simple thing for someone with experience.

Here is my code:

#define BLYNK_PRINT Serial
#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>
char auth[] = “xxxxxxxxxxxxxxxxxxxxxxxxxxxx”;

int ThermistorPin = 1;
int Vo;
int button;
int light;
float R1 = 10000;
float logR2, R2, T, Tc, Tf;
float c1 = 1.009249522e-03, c2 = 2.378405444e-04, c3 = 2.019202697e-07;
float batt;
int mailflag;
char ssid[] = “xx”;
char pass[] = “1234”;

BlynkTimer timer;

#define EspSerial Serial
#define ESP8266_BAUD 115200
#define BLYNK_MAX_READBYTES 256

ESP8266 wifi(&EspSerial);

void setup() {
button = 0;

batt = 0;
mailflag = 0;
EspSerial.begin(ESP8266_BAUD);

Blynk.begin(auth, wifi, ssid, pass,“blynk-cloud.com”, 80);

Hi,

Some suggestions:

  1. Remove the syncAll() from your routine, that is only needed in the initial setup() to cause Blynk to write values from the Cloud to your Arduino.
  2. Remove Blynk_Write(V2) from the loop as it will cause Blynk to cut you off as you can only make a few requests a second

Thanks guys.
