lcd.setCursor() function is used to set the location where we want to display character or text. The first argument to this function is a column number and the second argument is the row number. For example, this line sets the cursor position of the Arduino to the second row and first ...
Debouncing of the switch is done in software as these are not high quality switches, and it allows the long press detection used to put it in "Temp Set" mode.Many of our modern devices use a long press for another function, so the concept...

In this example, you can add only one LCD, and therefore it is imperative that you manage your pin resource count. methods(Hidden, Access = public) % InputPins is user input and contains the pins that connect the LCD Data Pins and the arduino function obj = LCDAddon(parentObj,varargin)...

of typeLiquidCrystal.The display can be controlled using 4 or 8 data lines.If the former, omit the pin numbers for d0 to d3 and leave those lines unconnected.The RW pin can be tied to ground instead of connected to a pin on theArduino; if so, omit it from this function's parameters...
