New to the ESP-01.... and need a little help!!
Posted: Sun Mar 17, 2019 12:22 pmHi all, I'm Alistair and very new to this great little board - be even better if I could get it to work how I want it to tho 
)
Any way, I digress. I have an ESP-01 and at the moment I have it setup when GPIO0 goes high, it sends a push notification to my Blynk app, and also on GPIO2 going high it sends another message to my Blynk app. Basically, I wish to monitor when a set of remote contacts open and close. What I would love is if I could have a notification if on one GPIO only goes high and when it goes low another message - is this possible please?
the code I have is this:
any help would be so greatly appreciated.

// You should get Auth Token in the Blynk App.

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "***********";
char pass[] = "***********";
int flag1 = 0;
int flag2 = 0;
void notifyOnButtonPress1() {
int isButtonPressed1 = digitalRead(0);
if (isButtonPressed1 == 1 && flag1 == 0) {
// We allow 1 notification per 15 seconds for now.
Blynk.notify("Dad is up and alarm is now unset");

}
}
void setup() {
// Debug console
Serial.begin(9600);
Blynk.begin(auth, ssid, pass);
// Setup notification button on pin 0
pinMode(0, INPUT_PULLUP);
// Setup notification button on pin 2
pinMode(2, INPUT_PULLUP);
timer.setInterval(16000 L, notifyOnButtonPress1);
timer.setInterval(16000 L, notifyOnButtonPress2);
}
void loop() {
Blynk.run();
timer.run(); // Initiates BlynkTimer
}any help would be so greatly appreciated.

I love the project section of this forum too - I shall spend many a happy moment looking.
