Re: SWR meter with second arduino
Thank you for your information
So far I don’t have a second Nextion. (In 2021?)
So my edit would be a main 5-inch Nextion and a 3.2-inch Nextion in secondary. So it should work.
Afterwards, I was wondering if it was possible to add an audio equalizer that we could drive with this 2nd screen. There are circuits controllable by the arduino.
with a MSGEQ7.
