  }

}

this is my code for esp32 cam module. whenever it receives a pulse from my other microcontroller, it should capture an image. but the loop is executing even if i dont connect it to other microcontroller. i can see the loop executing from my serial monitor output

Connecting to WiFi...
Connecting to WiFi...
Connecting to WiFi...
Connected to WiFi
Camera initialized
Not Connected to server
Camera capture failed
Camera capture failed
Camera capture failed

found the problem. serial begin should come after pin mode.

you got pinMode INPUT_PULLUP on this pin..
maybe you should be looking for LOW??

good luck.. ~q
