Hello,
Forgive me if this might seem like a very simple question with a very obvious answer. I get nervous when I’m trying something new. I have destroyed 4 devices because i have wanted to try do something ive never done before.
My question is how to safely configure a buzzer to notify me whenever i get a new message?
I bought several meshtastic starter kits (19007 base board with the rak4630). I also bought buzzers rak18001 for several of these kits. I have watched the YouTube video that goes into what you can do with external notification. In the video it says he put the gpio to 21.
When i go to the website it doesn’t say anything about putting the gpio number to 21. It mentions something about pwm buzzer. I’m not sure what a pwm buzzer is and i dont see anywhere in the settings where i can choose the option for a pwm buzzer.
So far i have installed the latest firmware to the rak4630 and installed the buzzer on slot C. What do i do next to make the buzzer go off whenever i get a new incoming message?
Here are what my setting look like so far:
