+This is the code for the camera to work. I have used the "CameraWebServer" example as a guiding point and I have done the necessary modifications.
+In it, I have modified the "httpds.cpp" file so that when the ESP32-CAM detects my face, it will send a message in the Serial. The message from the Serial is read by Arduino Uno through connecting it to the RXD and TXD pins of the ESP32-CAM. The message sends a voltage through the Relay Module and the Relay Module Opens the 12V Solenoid Lock making it open.
