Kerala's First 3D Printed Building

Created as a showcase project, AMAZE-28, the single-room summer house, was successfully constructed within 28 days on the grounds of the Kerala State Nirmithi Kendra. The 3D-printed building at the Kerala State Nirmithi Kendra in Thiruvananthapuram. (Photo: Shekunj)  The inauguration of Kerala's inaugural 3D-printed structure, a 380-square-foot single-room summer house, is scheduled to take place on October 10 at the Kerala State Nirmithi Kendra (Kesnik) campus located in PTP Nagar, Thiruvananthapuram.  Conceived as a showcase initiative, the summer house named AMAZE-28 was successfully finished within a mere 28 days. This impressive project was executed by Tvasta, a construction technology startup based in Chennai, founded by alumni of IIT-Madras, who have entered into a memorandum of understanding (MoU) with Kesnik.  AMAZE-28 is perched upon a concrete foundation atop a gentle elevation within the Kesnik campus.

How to make a Fire Alert System using Arduino

 Here, we are going to study about flame detection sensor and interfacing it with Arduino to make FIRE ALERT SYSTEM. It will detect fire (Flame) and create an alert. It can be implemented in a system like a fire extinguishing robot. So, let's get started. 😊😊💻


Components Required
First, we must collect the required components for this project. The list of all components is given below.
  1. Arduino UNO
  2. Flame Sensor
  3. LED
  4. Resistor (220 Ohm)
  5. Buzzer
  6. Bread Board
  7. Jumper Wires

Components needed for Fire alert System

Circuit Diagram -
Now we have to connect the flame sensor with Arduino at the input pins and buzzer and LED at output pins which we have defined in our code. The complete circuit diagram is shown in the image below.

Circuit Diagram of Fire Alert System 
 
We have seen the circuit diagram for the project. Now let's move towards the coding part of the project. Arduino code for this project is given below. 

// FIRE ALERT SYSTEM
// Project by - TechKnowLab

int sens = A0;  //Sensor pin
int led = 8;    // LED pin
int bzr = 9;    // Buzzer pin
int val = 0;    // variable to store the value of Sensor

void setup() {

  pinMode(sens, INPUT); 
  pinMode(led, OUTPUT); 
  pinMode(bzr, OUTPUT);
  
  Serial.begin(9600);

}

void loop() {
  
val = analogRead(A0);
Serial.println(val);
delay(100);

if ( val < 200 )
{
  Serial.println("FIRE!");
  digitalWrite(led, HIGH);
  digitalWrite(bzr, HIGH);
}
else{
  digitalWrite(led, LOW);
  digitalWrite(bzr, LOW);
}

} 
Now after preparing the Arduino code, let's flash it into the Arduino. After flashing the code in Arduino, our project is ready to work. Let's see the working of this Fire Alert System in the video given below.


I hope you like the post and learn about the flame detection sensor and how to interface it with Arduino to make a Fire Alert System. Keep exploring and expand your knowledge.

Controlling LEDs over WiFi using NodeMCU and Blynk App.

This article is the base on the Internet of things ( IoT ) . IoT describes the network of physical objects—“things” or objects—that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the Internet. In this article 3 LEDs will be controlled by an android application (made using Blynk) over a wifi connection. How to use NodeMCU with Blynk  If you want to start learn the Internet of Things (IoT) concept, then controlling a LED over the  internet is the " Hello World!" of the IoT journey. Performing the " Hello World" task will be easy using NodeMCU micro-controller as the first client and Blynk as the 'broker' or server and Blynk android application as the second client. Now communication between two clients will happen through broker over the internet. Now lets, make this happen.  Components Required For this activity we will need following components: Nod...

How to Know the NodeMCU IP Address for Your Next IoT Project

  NodeMCU IP Address: The NodeMCU is a popular development board for IoT projects. It’s small, affordable, and comes with built-in Wi-Fi connectivity, making it the perfect choice for creating connected devices. But before you can start building your NodeMCU projects, you need to know the IP address of your device. This IP address is essential for communicating with the NodeMCU from another device, such as a computer or smartphone. In this article, we’ll show you how to find the NodeMCU IP address, so you can get started with your next IoT project. Method 1: To Know the NodeMCU IP Address One of the easiest ways to find the NodeMCU IP address is by using the serial monitor in the Arduino IDE. First, connect your NodeMCU board to your computer using a micro-USB cable. Then, upload the following code to the NodeMCU: #include <ESP8266WiFi.h> void setup() { Serial.begin(115200); Serial.println(); Serial.print("Connecting to "); Serial.println(...

Blinking of LED Using Arduino UNO

Hi !!!! Here we are going to learn very very simple use of Arduino, that is blinking of a LED. Here we will do simplest project using Arduino. So, here we go.... COMPONENTS REQUIRED - Bread Board Arduino UNO Jumper Wires Power Source (5V) / Battery Resistor (1K) CIRCUIT PREPA RATION - Take bread board and Arduino. Connect the +5V from Arduino to the +Ve line on Bread Board and GROUND from Arduino to -Ve line on bread board. Red Wire     : +5 V Black Wire  : GROUND     Now put a LED on bread board. Connect the Anode (+ / Longer terminal) of led to the pin 13 of Arduino. Connect Cathode (- / Shorter terminal)  to 1K ohm resistor and connect another terminal of resistor to the GND on breadboard.   Now our circuit is ready to work.  Our next aim is to build the code. Let's make our code. CODE -     To download the complete code -  CLICK HERE -----------------------------...
