Thank you so much!!!

The lock seems to be 12V, not 9V. Is the 9V battery holder enough to really power the lock ?

Amazing video! Going to build one!!!

I think I am going to have to pick up a few of those UART MP3 players for ESP32 shenanigans! :)

They are awesome, and at least this one comes with a little speaker
