To make Alexa eyes, first we need to make two eyes with the help of 3D printer and connect those eyes to the servo. And ESP32-CAM should be installed with it which will recognize our face and follow human by XY measurement. And connect that camera to the microcontroller then connect all the servo motors to that microcontroller. And the program will be uploaded in the microcontroller then the person in front of that camera will actually follow that person's eyes and the input in the microcontroller will be the output of the device from the Alexa device. If you want to see how to output from Alexa Lite, you can follow a video already made in my YouTube channel. If anyone has any problem in making this device, please let me know in comments or via email and I will try to solve it, thanks. And to get the programming of this device click.... here.
