I searched on google about anxiety tests to detect if the user is an anxious person or not.
I found this test LINK
7 questions showed on LCD, the user can answer by push on (yes OR no)
then the result showed the degree of anxiety but but this test doesn't mean you are suffering from anxiety disorder.
If you want to know more about an anxiety disorder read this Article
Finally, i wanted to help these people by playing quite music (complete features) and emitting light according to the degree of anxiety.
Firstly, I wanted to make a robot so it can move and touch the user and hugging him, but i made it like a game! :D
My final project is a device that can helps anxious and nervous people to calm down by playing the music and emitting light that they love and provide support.
I thought about this project because I am an anxious person and it might help me become calmer.
this video for a similar idea.

For the complete features i had to use battery (7.4) volt
But i reached ti the minimum features so i didn't use the battery, i used the Adapter (5v) instead.
in minimum features i used:
RGB led
Temp sensor
LCD screen
Push buttons
All of them can work with 5v.

6- Describe the code of your project. How did you program each function of the project?
6- Describe the code of your project. How did you program each function of the project?
Dividing the code into two parts:
Writing the code of Temp sensor and RGB led.
#define LM35 A0
#define RED 6
#define GREEN 10
#define BLUE 11
float lm_value;
float temperature;
void setup() {
Serial.begin(9600);
pinMode(RED, OUTPUT);
pinMode(GREEN, OUTPUT);
pinMode (BLUE,OUTPUT);
}
void loop() {
lm_value = analogRead(LM35);
temperature = (lm_value * 500) / 1023;
Serial.println(temperature);//Temperature in Celcius
//Condition
if (temperature <= 25) {
digitalWrite(RED,LOW);
digitalWrite(GREEN,HIGH);
digitalWrite (BLUE,LOW);
}
else if (temperature > 25 && temperature < 30)
{
digitalWrite(GREEN,LOW);
digitalWrite(RED,HIGH);
digitalWrite (BLUE,LOW);
}
else if (temperature >=30 && temperature < 50){
digitalWrite(GREEN, LOW);
digitalWrite(RED, LOW);
digitalWrite (BLUE,HIGH);
}
delay(100);
}
temp = 29.8 so the RGB led emitting red light
2. Writing the code for LCD and 2 push buttons :
const int Yespushbutton = 2, Nopushbutton = 3;
int button1_State = 0, button2_State = 0;
float count_value =0;
char *myStrings[] = {"1- Feeling nervous?","2- Not being able to stop or control worrying", "3-Worrying too much about different things",
"4-Trouble relaxing", "5-Being so rlesests that it is hard to sit still", "6-Becoming easily annoyed or irritable",
"7- Feeling afraid something awful might happen"
};
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 16, 2);
void setup() {
pinMode(Yespushbutton,INPUT_PULLUP);
pinMode(Nopushbutton,INPUT_PULLUP);
lcd.backlight();
Serial.begin(9600);
lcd.init();
}
void loop() {
for (int i = 0; i<=6 ; i++) {
Serial.println(myStrings[i]);
Serial.println("Yes No");
lcd.clear();
lcd.setCursor (0,0);
lcd.print (myStrings[i]);
lcd.setCursor (1,1);
lcd.print ("Yes NO");
while( digitalRead(Yespushbutton) !=LOW && digitalRead(Nopushbutton)!=LOW){
for (int positionCounter = 0; positionCounter <18; positionCounter++) {
// scroll one position right:
lcd.scrollDisplayLeft();
// wait a bit:
delay(500);
button1_State= digitalRead(Yespushbutton);
button2_State = digitalRead(Nopushbutton);
if(button1_State == LOW || button2_State == LOW) {break;}
Serial.println(button1_State);
Serial.println(button2_State);
//delay(100);
}
}
}
}
define all variables and input data ( pins of push buttons)
(pins of RGB led, temp sensor)
(temp value and counter value)
entered the questions in array then
I include the header "Wire.h". This library help to communicate with I2C device. Then include "LiquidCrystal_I2C.h" for better communication with display.
Next set the address, number of column and number of rows using the function "LiquidCrystal_I2C lcd(). The address is 0x27 Number of columns is 16 and number of rows is 2. After this, we can call the display using "lcd".
Next code the setup part. First initialize the display using the function " lcd.init();"
initialize digital pin 2,3 as an input with the internal pull-up resistor
make RED, GREEN and BLUE OUTPUT pins
Firstly, temp degree will be displayed on LCD screen and according to its range the RGB led will emit certain color:
as if the temp is less than or equal 25 c the light will be red.
else if the temp between 25 and less than 30 the light will be green.
else if the temp between 30 and less than 50 the light will be blue.
The temp will be present until any body pressed on one of 2 buttons then, the questions will appear.
after each question there is count value that recorded the result as a points
At the end of the questions according to the summation of the points the result will displayed:
if the range between 0 :4 then print
("minimal anxiety") and take an action (light will be purple)
if the range between 5:9 then print
("mild anxiety) and take an action ( light will be cyan )
if the range between 10:14 then print ("moderate anxiety") and take an action (light will be yellow )
if the range between 15: 21 then print
("severe anxiety") and take an action
(light will be red)
This code for Minimum Features
Writing the code for all integrated circuit
const int Yespushbutton = 2, Nopushbutton = 3;
int button1_State = 0, button2_State = 0;

9- When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this project?
Firstly, i cut the first design but the dimensions of the device wasn't appropriate, so i had to redesign it again :)
you should mount the components on fusion to make sure that the dimensions are suitable to avoid my problem :"D
In he right part the no of flexible lines are too little so it couldn't reach at the end :''
The middle part the no of flexible lines are too much
the last part is good but!! the hole for speaker wasn't right so i changed the shape to ellipse to be more suitable
Before download the file into the machine you should make sure that there is no overlapping :"
