Arduino Basics Tutorial

Hi, today I am going show a tutorial of how to use an Arduino(basics):

There two parts of arduino code:

Void setup() and void loop()

Void setup() - The initial code run by the Arduino

Void loop() - The code that runs forever till the Arduino is disconnect

Arduino has two different types of pins:

Digital and Analog pins

Digital pins are numbered 0-13

Analog pins are numbered as A0-A6

Remember, after a line of code, use a semicolon.

A basic program uses two commands called digitalWrite or analogWrite and pinMode

digitalWrite is used to give an output to a specific digital pin

analogWrite is used to give an output to a specific analog pin

pinMode defines whether the device connected is an output or input device

Circuit diagram:

Here is some example code that makes an led blink:

intled= 2; // defines that led is connected to digital pin two

voidsetup(){

pinMode(led, OUTPUT); //defines led as a output device

}

void loop(){

digitalWrite(led,HIGH); //turns on led

delay(400) //waits for 400 milliseconds

digitalWrite(led,LOW); //turns off led

}

SERVO :

There is a whole library for servomotor

It is called Servo.h

there are 4 parts of code to make a servo move:

#include<Servo.h>-it adds the servo library to the code

Servo servo-renames Servo as servo

servo.attach()-attaches servo to desired digital pin

servo.write()-moves servo in the typed degree

Circuit diagram:

Here is the code to move the servo in 180 degree angle:

#include<Servo.h>;

Servo servo

void setup(){

servo.attach(9)

}

void loop(){

servo.write(180)

}

I hope you liked this tutorial!
