-Touch the feature to edit. (After touching, the "edit" will be appear at the right bottom.)
-For the text, editing should be done as follows:
-For the buzzer:
-Then, please set the circuit and upload the code. While the circuit is powered, open your phone's bluetooth and then connect it with the HC-05. This part is depends on your phone's model. If it asks you a pin while connecting to the HC-05, probably it is 0000 or 1234.
-Open the application. Choose the panel you did. Select "Connect" option. And Connect to the HC-05.
-Lastly, back to the menu and select the panel. Then run it. You can test it with a lighter. When flame detected, the text will change and the buzzer will start to buzz!
