Description in text for each coding part :

1. defining the LDR sensor (ldr) that it is connected to A0 as an analogue input.

2. defining the red pin (Rpin) in the RGB LED that it is connected to pin 9.

3. defining the green pin (Gpin) in the RGB LED that it is connected to pin 10.

4. defining the blue pin (Bpin) in the RGB LED that it is connected to pin 11.

5. The three values of the red, green, and blue will use integers (int) with no decimals.

in void setup

1. the serial begin is used for serial monitor to check any bugs and errors in readings.

2. the IR Sensor is defined as 6 (since this is the number of its pin in arduino) and it is input components, it means that it will be used in digital read to write on the output pins of the DC motor.

3. The digital pins of the servo motor, the output pins will be Pin 5 is controling the motor degree of rotation

in Void loop (Commands that will be repeated)

1. x is an integer value to store the readings of the ldr sensor (analog read) and it is analogue because we will recieve different number of light intensity values to lighten the RGB LED (Not Digital which means HIGH OR LOW , YES LIGHT IT OR NO DO NOT LIGHT IT).

2. the mapping here will scale the readings of the values produced from the ldr sensor from (0-1023) which is the default range of readings to ( 0-100).

3. The formula is as follows:

1) If the LDR readings (light intensity) are less than or equal to 17 then turn the purple color of the RGB LED so analog write on the red and green pins with values (75 and 130 respectively).

• serial print that LDR had received the light intensity values correctly.

• serial print that the RGB led has produced the right values on each pin as the equation.

2) If the LDR readings (light intensity) are more than 17 and less than or equal to 34 then turn the blue color of the RGB LED so analog write on the blue pin with values ( 50 ).

• serial print that LDR had received the light intensity values correctly.

• serial print that the RGB led has produced the right values on each pin as the equation.

3) If the LDR readings (light intensity) are more than 34 and less than or equal to 50 then turn the green color of the RGB LED so analog write on the green pin with values ( 255 ).

• serial print that LDR had received the light intensity values correctly.

• serial print that the RGB led has produced the right values on each pin as the equation.

3) If the LDR readings (light intensity) are more than 50 and less than or equal to 67, then turn the yellow color of the RGB LED so analog values are written on the Red and Green pin with values ( 255 and 255 respictevly ).

• serial print that LDR had received the light intensity values correctly.

• serial print that the RGB led has produced the right values on each pin as the equation.

4) If the LDR readings (light intensity) are more than 67 and less than or equal to 84 then turn the orange color of the RGB LED so analog write on the Red and Green pin with values ( 255 and 165 respectively).

• serial print that LDR had received the light intensity values correctly.

• serial print that the RGB led has produced the right values on each pin as the equation.

4) If the LDR readings (light intensity) are more than 84 then turn the red color of the RGB LED so analog write on the red pin with value ( 255 ).

• serial print that LDR had received the light intensity values correctly.

• serial print that the RGB led has produced the right values on each pin as the equation.

The Values of RGB LED STRIP COLOR ranges are from this website : https://www.rapidtables.com/web/color/orange-color.html?fbclid=IwAR3jxbgYA9YUyjb4zYL-fhifhY7swLHIAEfvKkuc_nbJHVIQ9SDO2IlCK_w

4) To read the IR sensor readings on pin 6, i wrote digital read pin 6 and if it reads a movement (High) please move the SERVO on pin 5 to a DEGREE of 70

5) if the latter didn't happen, make the SERVO stop on pin 5 and make the SERVO rotate to zero degree.

Integration:

1) I tried and tested the first input (ldr sensor) with the first output LED seperately to check that the LED is working.

2) then i tried the servo and tested it with IR Sensor.

3) both inputs and outputs of The project are integrated together and the LDR sensor is responding to the different intensities of the torch light. And the IR sensor is responding to any motion infront of the ablique which allows the servo to rotate in 70 degrees and cause the movement of the gears, then the gears moves the sticks attached to them and it causes the blooming effects of the fabric.

1) Amany has helped a lot. Firstly, in the coding part, I was intending to have both inputs from the microwave and IR sensor to make the blooming effect happen when someone passes in front of the ablique or just moves in the space within a range of 5 m because the IR sensor has a very limited distance to feel the motion, which might be less than one meter. I have developed a code for the latter; unfortunately, the code has worked but there was a confusion between both readings, so i reduced it to only IR since the microwave within crowds will not work well as suggested by Amany.

2) Ibrahim Raafat has helped me a lot and suggested that I could connect the LDR in an analog state instead of digital to feel the different values of the light intensity.

1) The push plunger was stuck in the shaft although I have clearance in the design of 0.2m but it happens because the PLA is not accurate after cooling so it expands and when the servo rotates it breaks the Push plunger so I replaced it with SLA material to gain some strength and become accurate in details.

2) I tried the code with RGB LED first before the LED Strip and the values of the RGB Ranges varied, so the analog indications are given in this chart https://www.rapidtables.com/web/color/orange-color.html?fbclid=IwAR3jxbgYA9YUyjb4zYL-fhifhY7swLHIAEfvKkuc_nbJHVIQ9SDO2IlCK_w

3) The gears does not rotate as it cannot hold the weight of the sticks so it stop and causes higher friction to the push plunger which prevent its movement so i had to lessen its length to the half in order to reduce its weight, prevents it from being broken and increase its strength and reduce the degree of the servo rotation from 90/180 to 70/60 which are optimum and it works well by then.

I will add decorative finishing (gold and shiny ) painting and make many of the blooming effect in layers such as the example shown in the video.

I will make it controllable using a Bluetooth module controller (graphical remote control application).
