Thank you for your answers.
If i want to use pin 12 and 13 for communication with the sensor, what do i need to change in the code so i can use these pins?

#include <Adafruit_Fingerprint.h>


#if (defined(__AVR__) || defined(ESP8266)) && !defined(__AVR_ATmega2560__)
// For UNO and others without ...

I am still fairly new to working with an esp32 cam and I have a question. Hopefully someone can help me.

I would like to connect my fingerprint reader to my esp32 cam and also use the adafruit fingerprint library. I just don't know which pins to use and how to indicate this in the arduino sketch ...
