6- Describe the code of your project. How did you program each function of the project?
First part: reed switch
first declare all pin from 2 to 7 as input
make if condition to check every reed switch is high, then print word in serial and show it on screen with app inventor.
include a counter to increase the checking and make sure that one word is appear.
at the end return the value of the counter to equal 0.
MIT app inventor geometric shapes part
get from the user interface, list Picker and put it on the screen, edit font size to 20, height to 60, and width to full parent (take the width of the phone ).
get from user layout a horizontal arrangement, with height 200, width full parent.
put in this horizontal arrangement a label from the user interface (here the word will appear), edit font size to 70, height to 200, and width to full parent.
get clock from sensor and put it on screen.
get Bluetooth client from connectivity and put it on screen.
first two block to connection with Bluetooth module.
make a variable to sort in it the received date from Bluetooth, the put this data in label to show it on screen.
Second part: RGB LEDs strips
first include library and definition the button pin to 7, pin of RGB to 6.
count of pixel is 1 strip (include 3 LED)
don't forget the bottom to input pull up.
first check for reading of button, the make a counter to count how many times to push button and get different color
at the end in for loop, return value of push button.
this function after for loop to clear the previous color, (this function in example of library)
MIT app inventor the same one of geometric shapes part

add another screen in the same project.
get from the user interface, list Picker and put it on the screen, edit font size to 20, height automatic, and width to full parent (take the width of the phone ).
upload all pictures needed in this part.
get from user layout a horizontal arrangement, with height 180, width full parent. put in this horizontal arrangement image 1.
get from user layout a horizontal arrangement, with height 80, width full parent.
put in this horizontal arrangement label1, 2, 3. with height fill parent and width 90, font size 25. and change the text in each one of it.
get from user layout a horizontal arrangement, with height 60, width full parent.
put in this horizontal arrangement label4. with height 60 and width full parent, font size 40.
add button to go back the first screen.
first two block to connection with Bluetooth module. and the button to return to screen 1.
making a condition to check if data from Arduino equal 1 then go to the second question, else if this not the correct answer. and increase the counter by 1/
checking number of counter and the correct answer in the second question, then go to another question and increase counter by 1
Arduino code of question part
declare pins
send number when push the button.

the feedback it was about design, it is better to making the slot is bigger and the part of door (moving part circle) it is so small comparing door dimensions.
the holes of geometric shapes better to increase 0.2 to make putting shapes smoothly way.

when testing RGB LEDs strips, it is not working.
until E/Ahmed Ibrahim discover that inputs pins soldered in output of LEDs strips.
distance between the reed sensor and magmatic in geometric shape is too big, so you should put the whole shape in the hole, and it this difficult to remove the shape again.
So, decrease this distance by decreasing the sides part to 15 mm. OR use a big nail with nuts to adjust the distance.
when answer right in question 1, so you get second question. But not happen, the second question already appear.
So, E/Ahmed Ibrahim suggest to make a counter to make double checking of condition, and butting if condition after first condition not inside it.
when putting all codes in one code, it not working correctly.
so, making functions each one included separated code and calling these functions in void loop, that make the code work smoothely.
include all library
declare all pin
call all functions in void loop.
pin 11 is toggle switch to moving between mode (1- RGB color and shapes
2- question party)
first function include changing color code.
second function include reed sensor.
third function include questions part
