A nice and simple project, you done relay good

If you are interested, here is some coding shortcuts that should work…

From this…

krc:

/************BISTABIL switch button android*************/ 
BLYNK_WRITE(V1) // virtual V1 BISTABIL relay1
{ 
  if (param.asInt()) {
    digitalWrite(relay1, HIGH);
    } else {
    digitalWrite(relay1, LOW);
    }
}

to this…

/************BISTABIL switch button android*************/ 
BLYNK_WRITE(V1) // virtual V1 BISTABIL relay1
{ 
    digitalWrite(relay1, param.asInt());  // use value provided by widget
}

And this…

krc:

/*****************MONOSTABIL push button android***************/
BLYNK_WRITE(V20)//all ON relay1,2,3,4,5,6 
{ 
if (param.asInt()) { 
    digitalWrite(relay1, HIGH); 
    Blynk.virtualWrite(V1, HIGH); 
    digitalWrite(relay2, HIGH); 
    Blynk.virtualWrite(V2, HIGH); 
    digitalWrite(relay3, HIGH); 
    Blynk.virtualWrite(V3, HIGH); 
    digitalWrite(relay4, HIGH); 
    Blynk.virtualWrite(V4, HIGH); 
    digitalWrite(relay5, HIGH); 
    Blynk.virtualWrite(V5, HIGH); 
    digitalWrite(relay6, HIGH); 
    Blynk.virtualWrite(V6, HIGH); 
}

To this

BLYNK_WRITE(V20)  // all ON relay 1,2,3,4,5,6 
{
  if (param.asInt()) { 
    for (int i=1; i <= 6; i++) {  // Loop from 1 to 6
    digitalWrite(i, HIGH); 
    Blynk.virtualWrite(i, HIGH);
    }
  }
}

```
BLYNK_WRITE(V20)  // all ON relay 1,2,3,4,5,6 
```

{
if (param.asInt()) {
for (int i=1; i &lt;= 6; i++) { // Loop from 1 to 6
digitalWrite(i, HIGH);
Blynk.virtualWrite(i, HIGH);
}
}
}
bad
BLYNK_WRITE(V20) // all ON relay 1,2,3,4,5,6
{
if (param.asInt()) {

```
for (int i = 1; i <= 16; i+=1) {  // Loop from 1 to 6
digitalWrite(i, HIGH);  
Blynk.virtualWrite(i, HIGH);
}
```

}
}
