Electronic, Craft, 3-D Ganesha

Electronic, Craft, 3-D Ganesha


Material: 2-D design print of Ganesha, Water color ,  Glue, 3-D Printed foundation stand, Sketch pens.

Electronic material: Arduino kit, Jumper wire, PCB, Battery 5 V, Connector, Breadboard, RGB LEDs

Tools:

Soldering Gun, Scissor

Lesson plan:

1. Make a 2-D print of Ganapati on bond paper.

2. Cut the design using scissors.

3. Join the Ganapati body parts as shown in sequence.

4. Paint each part of the body using colors, sketch pen or water color, color should be simple and sober.

5. Attached chakra behind the Ganapati head..

6. Now placed the Ganpati on the foundation.

7. Write a code for Arduino with ultrasonic sensor.

8.  Connect ultrasonic sensor with Microcontroller and do numbers of practicals, write code in such way that you will get lights on when you will be come in between 30 cm range from the system.

10. Mount the RGB lights on the PCB and soldering it properly.

9. Now attached your electronic system with the Ganapati foundation and do multiple trial before make it fix.  


Code:

#define echoPin 2 // attach pin D2 Arduino to pin Echo of HC-SR04

#define trigPin 3 //attach pin D3 Arduino to pin Trig of HC-SR04 

#define red_pin 7

#define blue_pin 8

#define green_pin 9

long duration; 

int distance; 

int i;

void setup() {

  // put your setup code here, to run once:

  pinMode(red_pin , OUTPUT);

  pinMode(green_pin , OUTPUT);

  pinMode(blue_pin , OUTPUT);

  pinMode(trigPin , OUTPUT); 

  pinMode(echoPin , INPUT); 

  Serial.begin(9600);

}

void loop() {

  // put your main code here, to run repeatedly:

  int ran_red;

  int ran_green;

  int ran_blue;

  ran_red=random(100,255);

  ran_green=random(100,255);

  ran_blue=random(10,200);


  digitalWrite(trigPin , LOW);

  delayMicroseconds(2); 

  digitalWrite(trigPin , HIGH);

  delayMicroseconds(10);

  digitalWrite(trigPin , LOW);

  duration = pulseIn(echoPin , HIGH);

  distance = duration * 0.034 / 2; 

  Serial.print("Distance: ");

  Serial.print(distance);

  Serial.println(" cm");


  if (distance<30){

      for (i=1; i < 4; i ++){

  

  analogWrite(red_pin , ran_red);

  analogWrite(blue_pin , ran_blue);

  analogWrite(green_pin , ran_green);

  delay (100);

  analogWrite(red_pin , 0);

  analogWrite(blue_pin , 0);

  analogWrite(green_pin , 0);

  delay(100);                   

        }

  }else {

  analogWrite(red_pin , 0);

  analogWrite(blue_pin , 0);

  analogWrite(green_pin , 0);

  }

}


Working:

When we bring something in between ultrasonic sensor within 30 cm range then the RGB leds lights will turn on. The Ganpati is made of paper and pen. The small Ganpati and foundation of Ganpati is made up of 3-D Printer.








Result:

When anyone comes toward the Ganpati within 30 cm range, then the Ganpati foundation lights will be automatically on.

Introduction to Ultrasonic Technology And Applications At Nalanda Labs:

It is an acronym for Sound Navigation & Ranging (SONAR)   Sonar is the technology of making use of sound waves to navigate, communicate and detect objects which are used for monitoring a particular area 24/7. It detects objects within 180 degrees and up to 8 meters. The word "sonar" comes from the first letters of "sound navigation ranging." Sonar can detect and locate objects under the sea by echoes, much as porpoises and other marine animals navigate using their natural sonar systems. In 1906, American naval architect Lewis Nixon invented the first sonar-like listening device to detect icebergs. During World War I (1914-18), a need to detect submarines increased interest in sonar. French physicist Paul Langévin constructed the first sonar set to detect submarines in 1915. At first, these sonar sets could only "listen" to returning signals. By 1918, Britain and the United States had built sonar sets that could send out, as well as receive, sound ...

Indian Space Research Organisation (ISRO)

Indian Space Research Organisation is the national space agency of  India.  Headquartered in Bangalore, established on 15 August 1969, under the chairman, Scientist Vikram Sarabhai.  It performs tasks related to space based applications, space exploration and development of related technologies. In 1972, the Government of India set up the Department of Space (DOS). This department directly reports to Indian Prime Minister.  ISRO works under the DOS. The Chairman of the ISRO is also the Secretary in the Department of Space.  The Indian space programme was driven by the vision of Vikram Sarabhai, considered the father of the Indian space programme. ISRO Structure  ISRO is managed by the Department of Space (DoS) of the Government of India.  Secretariat of DOS and ISRO Headquarters are located at Antariksh Bhavan in Bangalore. Space scientist K. Sivan is the current chairman of ISRO.  Important ISRO centres -  Satish  Dhawan  Space...

Structured Capacity Building of Teachers

To equip teachers with the knowledge and skills required to impart the new curriculum to their peers and students, we are actively engaged in building the capacity of teachers through a series of training and continuous support. In terms of academic intervention, we are actively involved in designing content that aligns with the curriculum. Simultaneously, the model emphasizes teacher capacity building through virtual and in-person training sessions, covering both content and the pedagogy of teaching computer science. The primary objectives of these sessions were threefold: to instigate a paradigm shift in teachers' perspectives regarding the significance of digital literacy for students, introduce and provide training on block-based coding tools like Scratch Jr, and impart effective pedagogical strategies for teaching computer science in classrooms. The initial virtual training took the form of a summer coding camp, engaging 40 teachers during the summer break. This four-week- lon...
