Arduino UNO R3 Without Cable in Pakistan

SKU: N/A

Arduino is a microcontroller and it is based on an open-source electronics prototype. It is easy to use the Arduino IDE. It consists of both physical programmable circuit board and a piece of software. In Arduino, we use simple C++ programming. It is one of the more popular boards. It is best for beginners. Arduino Uno rR3 Schematic is very simple. Arduino UNO Pinout / Pin Diagram is now available at Wikipedia and we gave the link below.

Arduino UNO R3 Atmega328 Without Cable Now in Pakistan

 

 

Arduino is a microcontroller and it is based on an open-source electronics prototype. It is easy to use the Arduino IDE. It consists of both a physical programmable circuit board and a piece of software. In Arduino, e use simple C++ programming. It is one of the more popular boards. It is best for beginners. Arduino Uno rR3 Schematic is very simple. Arduino UNO Pinout / Pin Diagram is now available at Wikipedia and we gave the link below.

 

Major Components of Arduino are the following :

 

It has one USB connector

One Power port

Analog  pins

Digital Pins

Reset button

Crystal oscillator

TX RX LEDs

One USB interface chip

USB Connector: This is a USB port used to load a program from the Arduino Integrated Development Board.

Power Port: The Arduino board can be powered through an AC-to-DC charger and it can also be powered by the battery.

 

 

Atmega328P has the following components

 

The flash memory of Arduino is 32KB.

2. It has RAM of 2KB.

CPU: it fetches instructions from flash memory and controls everything.

  1. it has (EEPROM) of 1KB. EEPROM stands for Electrically Erasable Programmable Read-Only Memory.
  2. Atmega328P is a Pre-programmed IC with a bootloader. This allows you to directly upload a new Arduino program into the electronic component, without using any external hardware programmer

Arduino input Pins: This microcontroller has “0 to 5” Input pins. Which get both Analog and Digital data

Digital Pins: “0 to 13” Pins are digital. These are used for Digital data.

Reset Switch: it is used to reset the Arduino.

Crystal oscillator: it has a quartz crystal that ticks 16 million times a second.

USB interface: Signal converted into the USB level . and then send to the next level that an Arduino UNO board understands.

TX RX indicator: Here, TX used for transmitting data, and RX used to receive data.

 

Code of LED Blinking of Arduino:

 

 

void setup() {                                        /*all setup files are here and it will load one time when we press reset button */

 

pinMode(LED_BUILTIN, OUTPUT);                  /* define pins here for Arduino Uno Programming  */

}

void loop() {                                         /* loop function will run again and again and forever until program will reset  */
digitalWrite(LED_BUILTIN, HIGH);          /* LED will turn ON  */

delay(1000);                                                /* Here is  delay for 1 mint */

digitalWrite(LED_BUILTIN, LOW);           /* LED will turn OFF*/

delay(1000);                                             /* Here is delay for 1 mint */

}
