To add characters, copy and paste a column. Connect the output of the new column (Q port of the upper-most D-flip flop) to the input of the stage to the left (bottom-left most multiplexer port). Remember to connect the multiplexer select signal and the clock to the new column as well.
Lastly, delete the the output of the first column (Q port of the upper-most D-flip flop) and create a new connection to the to the input of the new stage you’ve added (bottom-left most multiplexer port).

To begin transmission
Serial.begin(<baud rate>);
in the *.ino file to 300"attrs": { "frequency": "300" }
in the diagram.json to 300 as wellIf there’s no output from the Wokwi Arduino serial monitor, try toggling SW7 OFF and ON again.
Congratulations! You should now see your customized letters being output!
Note that garbage characters may be printed upon initialization.
