The used materials are specified in the document of the same name. Be shure the 7-segment display has the following pinout.

Both common cathode and common anode are supported. I wire bridge from the common pad tot the GND (common cathode) or to the +5V (common anode) wil wire the display correctly. The program will detect the display type and adapt the output in order to function properly.

Several versions of the Arduino Nano Supermini V3 USB-C exists. Pick the one with the following Pinout.

The screw terminals can be mounted at the top or at the bottom side, as required.

The software has the following parameters that must be set:

#define UPPERCASE   true   // true = AbCdEF, false = abcdeF
#define INV_LOGIC   true   // Inverse input logic: a negative voltage resembles a 1, a positive voltage a 0
#define PULL_UP     true   // Pull up resistor on input logic is requred
#define USE_DEMO    true   // After power on, the 16 digits are briefly shown

 Set these parameters as required.

Five bit (pentanair) display

When the principle of a hexadecimal character set is extended, a 32-bit word can also be displayed using more alphabetic characters.

The yellow letters have an unique pattern, the red ones do not. When the S is skipped, the X will be the last character. An alternative is to show the decimal point when a number is shown.
