Hello I installed a garden irrigation system with 2 relays. The codes are below.
The system goes offline after a while and does not work again without a reset.
Thank you for your help.
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
char auth[] = "xxxxxxxxx";
char ssid[] = "xxxxx";
char pass[] = "xxxxxxxx";
BlynkTimer timer;
boolean stateled = 0;
boolean prevStateled = 0;
void myTimerEvent()
{
Blynk.virtualWrite(V0,millis() / 1000);
Blynk.virtualWrite(V1,millis() / 1000);
}
void setup()
{
Serial.begin(9600);
pinMode(13, OUTPUT); // NODEMCU PIN D7
pinMode(12, OUTPUT); // NODEMCU PIN D6
Blynk.begin(auth, ssid, pass);
timer.setInterval(3000L, checkledstate);
}
BLYNK_WRITE(V0)
{
if (param.asInt()) {
digitalWrite(13, HIGH); Blynk.virtualWrite(V13, 255); Blynk.notify("led ACTIVADO");
} else
{
digitalWrite(13, LOW); Blynk.virtualWrite(V13, 0);
}
}
BLYNK_WRITE(V1)
{
if (param.asInt()) {
digitalWrite(13, HIGH); Blynk.virtualWrite(V13, 255); Blynk.notify("led ACTIVADO");
} else {
digitalWrite(13, LOW); Blynk.virtualWrite(V13, 0);
}
}
BLYNK_WRITE(V2)
{
if (param.asInt()) {
digitalWrite(12, HIGH); Blynk.virtualWrite(V12, 255); Blynk.notify("led ACTIVADO");
} else
{
digitalWrite(12, LOW); Blynk.virtualWrite(V12, 0);
}
}
BLYNK_WRITE(V3)
{
if (param.asInt()) {
digitalWrite(12, HIGH); Blynk.virtualWrite(V12, 255); Blynk.notify("led ACTIVADO");
} else {
digitalWrite(12, LOW); Blynk.virtualWrite(V12, 0);
}
}
void loop()
{
if (Blynk.connected())
{
Blynk.run();
}
timer.run();
}
BLYNK_CONNECTED()
{
Blynk.syncAll();
}
void checkledstate()
{
**stateled = digitalRead(13);**
** stateled = digitalRead(12);**
** if (stateled != prevStateled)**
** {**
** if (stateled == 0) Blynk.virtualWrite(V13, 0); Blynk.notify("led ACTIVADO");**
** if (stateled == 1) Blynk.virtualWrite(V13, 255);**
** if (stateled == 0) Blynk.virtualWrite(V12, 0); Blynk.notify("led ACTIVADO");**
** if (stateled == 1) Blynk.virtualWrite(V12, 255);**
** }**
** prevStateled = stateled;**
**}**
