Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)
This week my assignment idea is Design and Build a simple smart circuit that contains at least TWO action components that you can control wirelessly and Use either the Android GUI or PC GUI to control the action components.
This week my assignment idea is Design and Build a simple smart circuit that contains at least TWO action components that you can control wirelessly and Use either the Android GUI or PC GUI to control the action components.
So I was inspired by the video of the week.
how the circuit works:
When I press on number one on the phone the RGB will give specific light and seven-segment will show number one and the buzzer will give tone by specific frequency and when pressed on number two on the phone the RGB will give specific light different from the light in case number one and the seven-segment will show number two and the buzzer will give tone by specific frequency different from the case of number one.
and so the number 6.

Firstly, I started to design the circuit on the TINKERCAD platform to simulate the circuit and make sure that the components are fully functional and working as required.

The circuit diagram
I added the components and connect them together by using the wires and added resistors to the RGB to reduce the current and protect them from the burn.

Wiring of Bluetooth module
I connected the RX pin with two resistance voltage dividers (1k ohm and 2k ohm) because the RX needs 3.3 v only
In the next step, I started to write the code.
In the next step, I started to write the code.
I defined a variable with a type character to receive the data in it from the mobile application.
in the void setup, I made for loop to make the pins from pin 2 to pin 12 all of them OUTPUT, Then enabled the serial monitor.
In the void loop, I made the ARDUINO stop waiting for the value to be entered by the user.
If the user entered '1' do the following:
1-execute function one()
2-turn the RGB led with the values in code.
3-turn on the buzzer for 300ms by frequency 150hz.
If the user entered '2' do the following:
1-execute function two()
2-turn the RGB led with the values in code.
3-turn on the buzzer for 300ms by frequency 300hz.
If the user entered '3' do the following:
1-execute function one()
2-turn the RGB led with the values in code.
3-turn on the buzzer for 300ms by frequency 400hz.
If the user entered '4' do the following:
1-execute function four()
2-turn the RGB led with the values in code.
3-turn on the buzzer for 300ms by frequency 500hz.
If the user entered '5' do the following:
1-execute function five()
2-turn the RGB led with the values in code.
3-turn on the buzzer for 300ms by frequency 600hz.
If the user entered '6' do the following:
1-execute function six()
2-turn the RGB led with the values in code.
3-turn on the buzzer for 300ms by frequency 700hz.
function to turn on the seven-segment with the numbers from one to six.
It's time to build the project on the ground

I started to make the connections on the real breadboard according to the design on Tinker CAD
I connected the seven-segment in the common cathode display and connected the pins of the seven-segment from pin 2 to pin 8.
In the Bluetooth module connected the RX pin with two resistance voltage dividers (1k ohm and 2k ohm) because the RX needs 3.3 v only
I connected resistors (220 ohms) to the RGB pins to reduce the current and protect them from the burn.
finally connected the buzzer to pin 9
The circuit is working
I used an Avometer to know the value of the resistances.

I stuck with the code as I forgot how to code the BT module but I got back to the videos to see how it work and searched for easier ways to code it.
This link helped me solve the problem.
