Hi guys,
I am new to LED world. And i have a project in mind to do to my car.
I was just wondering. Is it possible to connect esp32 with wled to an android head unit. So i can power it and control it at the same time.
Without needing to connect wirelessly by anymeans
As far as I know the only way to control WLED is over the network. I believe the serial port is only for programming the ESP. But maybe I’m wrong?
That being said, you could connect your android head unit and the WLED ESP to the same wifi (like your phone hotspot) and then you can control it via the WLED app, as long as your head unit will allow the app to be installed. Then again, there’s usually a way to side-load apps onto devices that won’t natively allow you to install it.
As for power, you would need a 12v-5v buck converter, at least for the ESP. That way you can source power from pretty much any circuit in your car, like the ignition accessory circuit. That way it will turn on and off with the ignition.
There are protocols for controlling WLED via serial.
