I was looking for ways to teach students the basics of PLC and found the OpenPLC project. Opensource, free and uses the IEC 61131 standard.

Two years ago I searched for a way to connect my Arduino with my Alexa and came up with this simple solution.
Grate to have and envoy with friends. Made compact so you take it with you on the go.
The device presented is marble maze game that is controlled using a smartphone via Bluetooth connection.

If it does not work with the Bluetooth terminal app or my app we can say it will be the bluetooth module or the code for the Bluetooth module. This is good! we isolated the problem! I had also issues in the past when prototyping this. The code you uploaded to dropbox is not correct because you put library's in comments (using //).
I would recommend that you follow this tutorial to get familiar with the Bluetooth module: https://create.arduino.cc/projecthub/electropeak/getting-started-with-hc-05-bluetooth-module-arduino-e0ca81
Try to upload the code provided by the tutorial and test it out. Afterwards you can change the code to work for you. You are almost there! :-)
Let me know what your find (it is hard to troubleshoot from a distance...)
First of all, I checked your code and why is
//SoftwareSerial EEBlue(0, 1); // RX | TX
in comments ("//")?
In the app I made it so that you have to press a button for a long time (1s). If you did not change you may have to press the button longer.
Check if you are actually connected with the bluetooth module. If so the lights stops flashing of the Bluetooth module.
If the lights stop flashing of the bluetooth module:
Connect the Arduino to a PC or Laptop and open the serial communication. Then press a button and see if the Arduino is picking op something. If so let me know what you pick-up.
So try those two things and we will go further from there. You could also try downloading my original app and press a button and see if you can read it on your Arduino to make sure the connection is OK. I will check this blog tomorrow.
