Sources Of Inspiration
inspired by the fan at our homes that when we press the ON button a sound is released.
This week's assignment is to Build a simple smart circuit with at least TWO action components that you can control wirelessly.
so, i made a fan that when it works a buzzer works with it too.

My circuit utilizes ARDUINO to control 2 action components which are the buzzer and fan.
the circuit includes a Bluetooth module so I can control it from my mobile.
so, when i send number 1 to my circuit the fan and buzzer will work together and when i send number 2 it will be turned off.

Text Code
Before Void Setup
Before writing any code (orders) first i define the component's status before Void setup to preserve a place called x on the ARDUINO memory.
So I wrote all the pins and their components I connected before in the form of integers (int).
for the relay pin I put it on ~7 and the buzzer on ~3
and for the Bluetooth module I made it`s default number 0.
Make sure that the brackets, symbols & semicolons are in their places with the right number.
Void Setup
I am supposed to write any action I want to repeat only once Also it is preferable to define the outputs & inputs here so I don`t have to define it again in a void loop and to be easy for the Arduino to read.
My outputs in this circuit are a fan and buzzer.
Void Loop
For any order that I want to be repeated through the process I wrote it under the void loop.
I used the if else condition to make the buttons via my mobile link with the fan and buzzer.
what do I want to achieve?
when the user presses (send) number 1 on his mobile application ➡️ the fan and buzzer are ON.
and when the user presses (send) number 2 on his mobile application ➡️ the fan and buzzer are OFF.

after wiring and connecting the circuit and checked that my code is syntax wise is right my fan is working and the buzzer don`t want to.
i thought of changing the idea as i asked and searched a lot but with no results, until one of the instructors told me that there are 2 brackets left and it is not a syntax error that can appear while uploading but it is a logical error.
The 2 brackets needed

The reason was that: the digital write (buzzer, LOW) wasn`t inside any condition so it was happening with each reading for the loop and it was low but after I put the brackets it started reading it low only when I sent 2.
