Android lock pattern for nextion

Hello! Posting again here as the moderator kindly suggested i move the topic to the free chat.

Is it possible to create a nine dot unlock pattern which on correct input sends a signal to a relay. Sorry if that sounds stupid, but i'm new in this...

Thanks in advance!


every enhanced K model display is already factory-preflashed with such kind of unlocking demo ...


if you use a number keypad or a pattern input makes no difference ...


A relay can't be driven directly by enhanced K GPIO Pins, but with a simple darlington driver chip like ULN2803 it is no problem ...


In any case, you either need an


    - enhanced Nextion K model ...


or a


    - standard Nextion T model with additional MCU logic ...

 


Nextion also does not currently support drag
