Introduction:

Arduino is an easy-to-use electronic hardware platform with an open-source software onboard. In the simplest terms, Arduino boards can read inputs: like light falling on a sensor, finger on a button, or even a twitter message, these inputs are converted by Arduino into desired outputs. The outputs can be likes of activating a motor or turning an LED on or off; also it can even post something online. The possibilities are endless. You can make your controller do what you want by sending the instructions to the microcontroller. This can be achieved by using the Arduino programming language.

Arduino platform:

Arduino is a micro-controller platform that makes devices programable in simple and accessible ways. The ease of its use is furthered by the fact that the platform is opensource. It is composed of the following:

  • C/C++ for ARM and AVR Microcontroller.
  • IDE for Windows, Mac, and Linux.
  • The bootloader of Device.

The device bootloader is a program that comes pre-programmed on the Arduino microcontrollers and helps to load your code from the startup memory. When the system is turned on, the first code to run is the bootloader, which takes the program code from memory and begins running it. In the case of Arduinos, the bootloader often helps you load code to the computer through a USB cable rather than a more costly hardware programmer (or programmer in the system).

Arduino development board is blue, and it has the size of a credit card, although the dimensions and specs of boards vary with the model od Arduino. Arduino Uno is a low power, small-sized computer.

Arduino Uno:

The Arduino UNO is the perfect electronics and coding board to get started. If this is your first taste with platform tinkering, be assured that UNO is the most potent board you can start playing on. The UNO is also the most commonly used and recorded board within the entire Arduino family. In Arduino Uno, there is a handy addition of USB port, 14 optical
I/O pins, six analog pins, an Atmega328 microcontroller. This also facilitates serial communication with pins Tx and Rx.

There are several variants of Arduino boards released in the market, such as Arduino Uno, Arduino Due, Arduino Leonardo, Arduino Mega. Still, Arduino Uno and Arduino Super are the most popular models. If you are planning to build a project related to digital electronics, embedded systems, robotics, or IoT, then the safest, most straightforward, and most economical alternative will be to use Arduino Uno.

UNO has the following specifications:

  • Operating Voltage: 5V
  • Input Voltage (limits): 6-20V
  • Analog Input Pins: 6
  • Input Voltage (recommended): 7-12V
  • Microcontroller: ATmega328
  • Digital I/O Pins: 14
  • DC Current for 3.3V Pin: 50 mA
  • DC Current per I/O Pin: 40 mA
  • Flash Memory: 32 KB of which 0.5 KB used by bootloader
  • EEPROM: 1 KB (ATmega328)
  • SRAM: 2 KB (ATmega328)
  • Clock Speed: 16 MHz

Getting started with Arduino Programming:

Arduino programming is based on C language, which eliminates the difficulty of assembly language, which means Arduino IDE converts code written in C into Assembly Language. IDE has a code editor, a code uploader, and a compiler. We can add different libraries for ports, sensors, and various types of displays.

Applications:

We can use Arduino for many projects. Some of them are written below:

  1. Educational Computing projects/ research.
  2. Rapid Prototyping.
  3. Interactive experiments.
  4. We can use it for controlling hardware with minimum knowledge.

What it can do:

As we discussed earlier, the possibilities of what you can achieve with this small yet powerful devices are seemingly endless, however here a few are mentioned for you:

  1. Internet of Things (IoT).
  2. Making security devices for the home.
  3. Automatic Opening Dustbin with Ultrasonic Sensor.
  4. Making line following robot.
  5. To measure Temperature.
  6. Window Aircon controller.
  7. Washing Machine.
  8. Microwave Oven.
  9. Security Systems.
  10. CCTV Switchers.
  11. For making Drones
  12. For making Line follower Robot.

Why should we be using Arduino:

Well, this is something that you must explore for yourself. However, we have pointed out a few of the many benefits here:

  • Arduino is entirely open-source.
  • It is easy to program and control.
  • It just needs 5 Volt to operate.
  • A USB port can power it.
  • We can use it to make cool and amazing projects, e.g. Automation, Surveillance, GSM Controlled projects.

 

Here is an idea for your first Arduino Project

Simple LED Blinking with Arduino

LED Blinking project is already saved in Arduino IDE cc for beginners

Tools:

We will need the following components for −

  • 1 × Breadboard
  • 1 × Arduino Uno R3
  • 1 × LED
  • 1 × 330Ω Resistor
  • 2 × Jumper

Implementation:

Step 1: attach pin 13 to a position on your Arduino breadboard, and then your resistor. Insert your LED, on the other side of the resistor.

NOTE: LEDs are divided, and if you don’t blow them, they have some way they need to be linked. Attach the LED ‘s positive lead to the resistor and run a wire at the Arduino from the ground to the GND plate.

Step 2: Download Arduino IDE Software from https://www.arduino.cc/.

Now for half the coding. Here’s where Arduino ‘s true magic occurs. You can program this little blue board to do just about anything you can think of. For this, the code we need to write is relatively easy.

How to code:

When you have Arduino IDE mounted on your device, connect the board to your machine using a USB cable. Now open the Arduino IDE and select the correct board by selecting Tools > Boards > Arduino / Genuine Uno, and by selecting Tools > Net, choose the accurate net. Arduino Uno is programmed using Wiring based Arduino programming language.

Code:

// the setup function runs once when you press reset or power the board

void setup() {

pinMode(8, OUTPUT); // initialize digital pin 8 as an output.

}///////////////////////

void loop() // the loop function runs over and over again forever

{

 

digitalWrite(8, HIGH);   // turn the LED on (HIGH is the voltage level)

delay(1000);                       // wait for a second

digitalWrite(8, LOW);    // turn the LED off by making the voltage LOW

delay(1000);                       // wait for a second

}
