this is what i came up with:
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "8d82695b6d7cxxxxxxxxx";
int rcvpin=A0;
void setup()
{
Serial.begin(9600);
Blynk.begin(auth, "TP-LINK", "yyy");
pinMode(rcvpin,INPUT);
}
void loop() {
int ldrval=analogRead(rcvpin);
if(ldrval<100)
{
Blynk.virtualWrite(5, HIGH);
}
else {
Blynk.virtualWrite(5, LOW);
}
Blynk.run();
}
