JSON from serial port - basic question

Hi All,

I am in the planning stages. I want to drive analog LEDs with WLED, I have an ESP32 board which I intend to configure to use WLED and PWM. I have an additional MCU handling display and input knobs, my intention is for it to commands to the ESP32 which is running WLED via serial communication lines using JSON, which I know very little about at this time. I like the idea of having local control the LEDs (RGBW) sending JSON commands to the ESP32, plus the possibility of external control using an App on a mobile or tablet. Does what I am describing sound reasonable and will it allow full access to WLED (obviously with the limitations of the analog LEDS).

Grateful for any replies on this matter.


You can also try rotary encoder and have everything on a single ESP.
