- The Folding Stars
THE PROJECT IDEA is a movalble unit react to the moving of people infront ofit with open and close according to them by servo motor and ultra sonic sensor or using manual mode using reostat
THE INSPIRATION and THE SOURCE OF THE IDEA
Becuase I am architect i am very interest in the interactive building
and bring the units of the building to life
for increasing the function and range of using any architecture product
by changing the amount of opening in the building (in ceiling or in the wall ) it can be used for decoration in the wall of the space
it can be used for opening and closing window ass people move beside it for adding dimanizm to the building
HOW DOES IT WORK
The first Button : on/off switch
The second Buttom : manual/sensor mode
the slider : The manual mode
fusion and softwares work
IN 3D PRINTER using PLA
after save the G.Code in prusa
and checking the suppert and amount grams used and layers thickness
adding it in the memory of the 3dprinter
preheatthe nozzle and bed to remove the used color
then select the G.code to print
IN THE LAZER CUTTER using MDF 3MM
after saving the file in the lazer worker
switch on the machine from the side two witch in of the screen and other before the process of he cutting
move the nozzle to the point and select orgin to make it the orgin of the machine
open the file in the lazerwork and chech the lines and the overlabing
select download then in the machine select the downloaded file
Project Electronics & Power Management
A- the INPUT component are reostat , two buttoms and ultra sonic sensor
the function of 1- buttom 1 is to turn on the device
2 -buttom 2 is to turn fro the manual to the automatic mode
3 -the reostat is the manual mode used to open and close the unit manually
4 -the ultrasonic sensor is the automatic mode used to open and close the unit automaticlly
B- the OUTPUT (action)component are two servo motore
the two motor rotate opposite to each other used to open and close the movable unit
C- using arduino to connect them to gether to controll it by progamming to form smart system
5. What is your power source? How did you select the suitable power source for your project? (List the softwares/tools/components...etc that you used)
the two servo need only the supply from the 5 volt in the arduino (parallel)
and the ultra sonic sesnor power source is the 5 volt in arduino
so
the power supply is the 6volt adaptor and all component get power from the 5 volt pin
Project Programming
define the ultrasonic for sending and receiving ultrasonics
define varriables and servo motor
define the pins of the servo motor
the void loop using if condition for the (manual and automatic )modes
to move the servo moter in opposite direction anticlock and clock wise
long distance_y = 0;
#include <Servo.h>
Servo myservo; // create servo object to control a servo
Servo myservo_2; // create servo object to control a servo
int potpin = A0; // analog pin used to connect the potentiometer
int val; // variable to read the value from the analog pin
long readUltrasonicDistance(int triggerPin, int echoPin)
{
pinMode(triggerPin, OUTPUT); // Clear the trigger
digitalWrite(triggerPin, LOW);
delayMicroseconds(2);
// Sets the trigger pin to HIGH state for 10 microseconds
digitalWrite(triggerPin, HIGH);
delayMicroseconds(10);
digitalWrite(triggerPin, LOW);
pinMode(echoPin, INPUT);
// Reads the echo pin, and returns the sound wave travel time in microseconds
return pulseIn(echoPin, HIGH);
}
void setup() {
myservo.attach(9); // attaches the servo on pin 9 to the servo object
myservo_2.attach(5); // attaches the servo on pin 9 to the servo object
Serial.begin(9600);
}
void loop() {
// long distance=(map(distance_y,0,50,0,30));
Serial.print("switchc-/=");
Serial.println(digitalRead(2));
if(digitalRead(2)== HIGH) {
val = analogRead(potpin); // reads the value of the potentiometer (value between 0 and 1023)
// scale it to use it with the servo (value between 0 and 180)
myservo.write(map(val, 0, 1023, 0, 180)); // sets the servo position according to the scaled value
myservo_2.write(map(val, 0, 1023, 180, 0)); // sets the servo position according to the scaled value
}
else if(digitalRead(2)== LOW){
distance_y = 0.01723 * readUltrasonicDistance(6, 3);
myservo.write(map(distance_y, 0, 30, 0, 180)); // sets the servo position according to the scaled value
myservo_2.write(map(distance_y, 0, 30, 180, 0)); // sets the servo position according to the scaled value
delay(1000);
Serial.println(distance_y);
}
}
Project Integration & Testing
7. Demonstrate with text and visuals how did you integrate the project’s modules together? What are the testing results? (Include a Demo video separately, showing a proof of functionality)
first and check the mechanizm of this movement in the project
then i add the other parts
the main part connect the all part together
connection the other part with it with the component
