Vcc- Connect to 5V of positive voltage for power
Trig- A pulse is sent from it for ranging more for object detection
Echo-check the object has been detected or not. If the signal comes back means the object has been detected, if not object has not been detected.
GND- It means Ground terminal, It completes the pathway of the power.

ULTRASONIC SENSOR

This ultrasonic distance sensor provides steady and exact measurements of the distance between 2 cm and 450 cm. It has less than 15 degrees of focus and a range of almost 2 mm.

Ultrasonic sound waves have an extraordinarily high pitch that can not be detected by humans

This particular sensor transmits an ultrasonic sound that is around 40 kHz in frequency. The sensor has two main components-a transducers that generate an ultrasonic sound wave, while its echo is listened to by the other portion

LED Blinking Program For Arduino UNO

Hello everyone, Now in this blog we are going to make LED Blinking Program for Arduino UNO, which is the basic project of the embedded system.
Let’s puts some LEDs and resistors to work. In this project, we will use one led and some resistor to make our project perfect (LED Blinking Arduino UNO).

LED Blinking Arduino UNO Algorithm

Before starting to write the algorithm of the project first know what is an algorithm. Basically Algorithm is a step-by-step method, which specifies a series of instructions to be executed to get the desired output in a certain order.

Algorithms are usually generated independently of the underlying languages, i.e. in more than one programming language, an algorithm may be implemented.

So, start writing the algorithm of our first project #1. Before going onto the algorithm part you should have a clear understanding of what is an Arduino UNO and basics parts.

Turn on the LED 1
Wait for a second
Turn off the LED 1
Repeat this process indefinitely
Required Components For LED Blinking Project In Arduino UNO
One led
A Resistor
One Bread Board
Wires
Arduino
USB Cables

Arduino Code For LED Blinking

Here is the code for LED Blinking Program.
lED BLINKING

//initialize variables (for pin)
int ledPin = 11;

void setup()
{
  //set the pin mode to output 
  pinMode(ledPin, OUTPUT);
}

void loop()
{
    // send a HIGH(ON) signal to ledPin which is pin 11
    digitalWrite(ledPin, HIGH);
    delay(1000);
    digitalWrite(ledPin, LOW);
    delay(1000);
}

In void setup() at the digital, I/O pins are set to outputs because we want them to send current to the LED on demand. We specify when to turn led using the digitalWrite() function in the void loop() section of the sketch.

Use Variables

In a computer program, data is stored using variables. For instance, in Project (LED BLINKING ARDUINO UNO) we used the delay(1000) feature to hold the LED Turns on.

What Is An Arduino UNO? – Beginner’s Guide

If you want to play with different electronic components but you don’t have enough knowledge of how to work with them, then Arduino is what you need to get started … So what’s an Arduino UNO?
Hello everyone, Welcome to my new Embedded System and Robotics blog. Whenever you think of the word Robotics, one thing that would also strike your mind is how the robotics work? How is the Robotics operated?

Arduino is essentially an open-source stage used for the construction of hardware ventures. Arduino consists of both a physically programmable circuit board (regularly referred to as a microcontroller) and a bit of programming, or IDE ( Integrated Development Environment) which suddenly spikes in demand for your PC, used to compose and transfer PC code to the Arduino UNO physical board. for info click here (https://hackthedeveloper.com/what-is-an-arduino-uno/)
