Signed Int

Value of In A is displayed as signed integer value (decimal, -8..7).
In B sets the mode, how the value is interpreted.

Unsigned Int

In A and In B are interpreted as one word and displayed as unsigned integer (decimal, 0..255). The right decimal point shows the 100, the left one (together with right) 200.

Alpha/Analog

In analog modes the analog value of pin A1 is read and displayed.
In animation mode the digital value of A is used for the output.
In alpha mode the digital value of A and B combined are displayed as ASCII character.
