Hi,

 

I want to introduce a new project of me. A friend asked me for help with his Lincoln stretch  limousine car. The car has originally an interior control via capacitive sensor keys based on a Atmel controller.  This solution have some big disadvantages: unlogical and unergonomic user interface, only one control in the passenger room (but only basic controls for the driver), no support for mobile devices and not ready for future  expansions. Our new solution based on WiFi and UDP protocols. We've developed 2 new boards. A new main control board and a new touch screen driver board for a Nextion touch screen. Both works with wemos d1 mini (esp8266) ....
