Why the author is acting hostile ?? Here is description of my method for frequency detection using resonance sensors from 2019! https://bialamusic.com/resonance_frequency_detection/

If you want to cooperate - I am open for that and I can share more. But this is public knowledge and should stay that way. Why you are deleting my comments in youtube - I have apps with 100K+ installs using such method and I can share details if you are really interested
