/* * MENU-program med Arduino UNO eller MEGA 2560 * -------------------------------------------- * Programmet bruger standard "LiquidCristal.h". * Programmet "rotary.h", kan hentes her: * http://www.planker.dk/Projects/Arduino/Rotary_Button.zip * Der findes mange versioner af Rotary.h, og ikke alle passer til * dette program, men ovenstående er den jeg selv har brugt, og * som jeg ved virker. * * Programmet er oprindeligt designet af Carlos Silas hvis DEMO af * programmet jeg fandt på YOUTUBE. * */ #include #include // rotary handler: LiquidCrystal lcd( 2, 3, 5, 6, 7, 8 );
