My programming skills are very limited and, as a result, I’m having a rough time understanding how to integrate an external component into ESPHome.
I have successfully created an ESPHome sensor that uses an 8266 with a microphone connected to the ADC. I leveraged (stole lol) the YAML to make this work.
Initially, I just wanted to detect a loud noise (triggering on a sound level). Instead, now I want to trigger when a specific frequency range is detected. I have this code in a separate sketch and it works. The target frequency is a fixed value. And, all I really need is a binary sensor that is set when the frequency is detected.
It seems that would be an extremely simple external component.
If you’ve done something similar, I could sure use some guidance. The example I found online on how to do this was way more complex and I got lost :(.
