Collaborated with Lanni Zhou.

Challenge 1: My buzzer does not work with Nano 33…..

Solution: Used a Uno instead and it worked.

Challenge 2: It had generated noise but melody.

Solution: The issue is due to the buffer data from Serial.read(). Just add one line code while(Serial.read() >= 0) ; to stop receiving incoming data from serial communication.

Next Step:

If we had more time to work on this, we would like to give the work a nice enclosure. For example, a cute toy to attract users’ attention. Maybe also hide the camera inside the toy or somewhere. So there will be no need for computer anymore.

Thank you.
