i erased all “led” and “lcd”.
void setup()
{
// Debug console
pinMode (RELAY,OUTPUT);
digitalWrite(RELAY,LOW);
Serial.begin(115200);
delay(100);
pinMode(SDCARD_CS, OUTPUT);
digitalWrite(SDCARD_CS, HIGH); // Deselect the SD card
Blynk.begin(auth);
// You can also specify server:
//Blynk.begin(auth, "blynk.cloud", 80);
//Blynk.begin(auth, IPAddress(192,168,1,100), 8080);
// Setup a function to be called every second
//timer.setInterval(1000L, myTimerEvent);
//delay(100);
timer.setInterval(1000L, sendUpTEMPERATURE);
}
i think, my SD card is inactive and it is before my Blynk.begin command.
if i dont use, i cleared all of them.
i think, i cant understand…
i erased the button, i won’t use. i think, i can use buton or slider, but it is not succes. so i can only use the slider.
generally, i think, i solved the problems, isn’t t? please let me know if there is something I did not do or did not understand.
My sketch’s last version is ;

i was added only 1 timer…
