smart desk lamp

This desk lamp is different in these points …..

It lights when there is a person or motion and the light is weak or there is no lighting but if there is more lighting and motion it doesn’t work

I care about this idea because of some reasons;…..

first,this idea shows very simple and I like the simple idea and work about it to show very beautiful and very flexible

Second I need to make this idea to use it for my desk to use it when I study

My inspiration was my desk needed a desk lamp and I think that why I make this but more function I see this idea on the website but another function and this is the link to the website

Supplies

List of Components

1 Arduino UNO
1 Breadboard
Wires
1 ultrasonic
1 LDR
1 Relay
1 Bulb
1 Screw cap
2 potentiometer
2 servo motors
1 Electrical plug
1 adaptor (6 v)
Spacers

Softwares

Fusion 360 (CAD Software)
Arduino programming
Tinkercad

Tools

Drill
Laser Cutting Machine
3D Printer
Screwdriver

Step 1: Test the Circuit

I write the code on Arduino programming and make the circuits by using these steps :

Connect the Arduino to the breadboard by putting the positive (5v) and negative (ground) pins on the (+) , and (-) on a breadboard
Put the LDR on the pin (4) on Arduino and (+) (-) on a breadboard
Put (ultrasonic ) (echo ) on pin (2) (trig ) on pin (5) on Arduino and (+) (-) on a breadboard
Put the potentiometer on one of them on the (A0) and the other on (A1) on the Arduino and (+),(-) on the breadboard
Put the servo motor on pin (11) on Arduino and the other on (9) and put the other weirs on (+), and (-) on the breadboard

Step 2: CAD Design

I used fusion software to design a smart desk lamp and I used some tools to design it like Sketch, offset, projection, Extrude, revolve Joints, and Filet

The CAD process of the project

1. I design a drawn circle to make the bases of the lamp by using offset and extrude.

2. make a rectangle to make the arms in this step by using the sketch and offset

3. use a joint tool to join the parts of the design and the part of the lamp I used to make it revolve, extrude, and filet

4. I port nuts and nails to make the hole in the arms

Put Arduino, relay, ultrasonic, and servo motors

Step 3: Fabrication

I designed the shape of the desk lamp on fusion and I used a laser cutting machine to cut the two bases and the four arms

I used 3D printing to print the part of the lamp and the part of ultrasonic

Step 4: Assemble

I used the help of my EX to make this Project Actually, so I appreciate her help

Step 5: Coding

#include <Servo.h>
Servo myservo2;  

int potpin2 = 0;  
int val2;   

Servo myservo;  

int potpin = 0;  
int val;    
int ldr = 4;
int bulb = 3;
int trig = 5;
int echo = 2;
void setup() {
  myservo2.attach(11);
  myservo.attach(9); 
  pinMode (ldr, INPUT );
  pinMode (bulb, OUTPUT);
  pinMode (trig , OUTPUT);
  pinMode (echo ,INPUT );
  Serial.begin(9600);
}
void loop() {
  long duration, cm;
  digitalWrite(bulb, LOW);
  delayMicroseconds(echo);
  digitalWrite(bulb, HIGH);
  delayMicroseconds(trig);
  digitalWrite(bulb, LOW);
  duration = pulseIn(echo, HIGH);
  cm = duration/29/2;
  Serial.print(cm);
  Serial.print("cm");
  Serial.println();
  delay(100);
  int motion ;
  if (cm < 30) {
    motion =1 ;
  } else {
    motion =0;
  }
  int brightness = digitalRead (ldr);
  if (motion){
  if (brightness) {
    digitalWrite (bulb, HIGH);
  } 
  else {
        digitalWrite (bulb, LOW);
  }
  Serial.print(brightness);
  Serial.print(",");

  }
  else {
    digitalWrite( bulb, LOW );
  }
  val = analogRead(potpin); 
  Serial.println(map(val, 0, 1023, 0, 180) );        
  val = map(val, 0, 1023, 0, 180);     
  myservo.write(val);   
  val2 = analogRead(potpin2);            
  val2 = map(val2, 0, 1023, 0, 180);     
  myservo2.write(val2);                  
  delay(15);
