Hey, for my project I want to allow my Arduino Uno to be able to control a lcd display with a message that appears when a face is detected. the part I don't know how to do is get the esp32 to communicate when is finds face with the Arduino. Anyhelp?
Okey. So finding/recognizing a face is already done? Only telling the Uno is the problem?

Do you really need the UNO?
You can connect the LCD to the ESP32.
