# Works on Pi 3B,5
# Free to use and enjoy and modify, but at your own risk.
# By W1AN
# Used with 'bookworm' 64bit with desktop on RazPi 5 and also works on Pi 3B. May work on others.
# Recommend using USB sound adapter cord.
# sudo apt install python3 but likely already installed
# sudo apt install mpg123 (audio player), sudo apt install minimodem for files.
# sudo apt remove python3-rpi-gpio (RazPi 5 only with new chipset), then:
# sudo apt install python3-rpi-lgpio for RazPi 5 with new chipset
# add ~/start-tty.sh to .bashrc in your user folder for start on boot without login
# add ./gpiotty27.sh to new start-tty.sh in user folder
# in your user folder create executable start-tty.sh with ./gpiotty27.py after sleep 5
# A and C on SW1, D and F on SW2, G and I on SW3, etc., with ~300-470 ohm resistor on Common to Gnd.
# Wire optically coupled relay to OutputA if needed.
