It has an RGB LED and an LCD screen.It gets input through a mobile GUI with a Bluetooth module. Then, based on the input, it performs the following actions:
When the code receives '1':
It turns on the red LED.
It displays "DANGER" on the screen.
When the code receives '2':
It turns on the green LED.
It displays "GOOD" on the screen.
If the code receives any other number, or if no input is received, the system displays an NO SIGNAL
It turns off all the LEDs.

HERE IS THE FINAL WIRING
the wiring
The code controls two things: an RGB LED and an LCD screen It gets the input through Mobile GUI with a Bluetooth module, and based on what it receives, it performs the following actions:
When the code receives '1':
It turns on the red LED.
It display DANGER on the screen
When the code receives '2':
It turns on the green LED.
It display GOOD on the screen
If anything else is received (or no input at all):
display NO SIGNAL
It turns off all the RGB LED.
the circuit connection
i connected the bluetooth module with the application
i chose bottons and slider
i started to control the circuit with the mobil app
Title of Media
i struggled a lot to do the current divider circuit to protect the Bluetooth module from being burned and i doit this way at the end and its working
THE KEY OF SOLUTION IS trial and error
