Introduction to Microservice Architecture Using SpringBoot - Part 1

 What is Arduino?

Arduino is a single board, microcontroller-based open-source electronic development board. Over the years, Arduino has been helping makers- students, hobbyists, programmers, and professionals- implement their idea. The main reason for being so famous is easy to use, open-source, and huge library support. All most of all types of sensors are available for Arduino.

History of Arduino 

Arduino is a hardware and software company. The Arduino project began in 2005 aiming to provide a low-cost device that can interact with the environment using sensors and actuators.

Types of Arduino board 

There are a lot of boards available in the market. some of the following are :

1. Arduino Uno (R3)
2. Arduino Nano
3. Arduino Micro
4. Arduino Due
5. LilyPad Arduino Board
6. Arduino Bluetooth
7. Arduino Diecimila
8. RedBoard Arduino Board
9. Arduino Mega (R3) Board
10. Arduino Leonardo Board
11. Arduino Robot
12. Arduino Esplora
13. Arduino Pro Mic
14. Arduino Ethernet
15. Arduino Zero
16. Fastest Arduino Board

Arduino Uno

 Arduino Uno is the most frequently used board, in this article we will discuss Arduino Uno.

"Uno" means one in Italian and it refers to Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the base versions of Arduino which was developed at the initial stage.

It is based on the ATmega328P   microcontroller. It has 14 digital input/output pins and  6 of them can be used as PWM outputs. It also has 6 analog inputs pins. Its working frequency is 16 MHz which is provided by a ceramic resonator (CSTCE16M0V53-R0) and also has a USB connection, a power jack, an ICSP header, and a reset button.

Tech Specification :

Microcontroller	ATmega328P
Operating Voltage	5V
Input Voltage (recommended)	7-12V
Input Voltage (limit)	6-20V
Digital I/O Pins	14 (of which 6 provide PWM output)
PWM Digital I/O Pins	6
Analog Input Pins	6
DC Current per I/O Pin	20 mA
DC Current for 3.3V Pin	50 mA
Flash Memory	32 KB (ATmega328P) of which 0.5 KB is used by the bootloader
SRAM	2 KB (ATmega328P)
EEPROM	1 KB (ATmega328P)
Clock Speed	16 MHz
LED_BUILTIN	13
Length	68.6 mm
Width	53.4 mm
Weight	25 g

Arduino Software (IDE) :

Arduino IDE is to program the Arduino board. we mainly use the c++/c language to program the Arduino board. we can also use python.

EXAMPLE CODE :

void setup() {

  pinMode(13, OUTPUT);

}

void loop() {

  digitalWrite(LED_BUILTIN, HIGH);   

  delay(1000);                      

  digitalWrite(LED_BUILTIN, LOW);    

  delay(1000);                     

}
