Arduino Uno R3 Board Compatible
The Arduino Uno R3 Board compatible is a microcontroller board based on the ATmega328P microchip. It is a popular and widely-used board in the Internet of Things (IoT) and robotics communities. This documentation provides an overview of the board's features, specifications, and code examples to demonstrate its usage in various contexts.
Features and Specifications:
Microcontroller: ATmega328P
 Operating Voltage: 5V
 Input Voltage: 6-20V
 Digital I/O Pins: 14
 Analog Input Pins: 6
 Analog Output Pins: 0
 Flash Memory: 32KB
 SRAM: 2KB
 EEPROM: 1KB
 Clock Speed: 16MHz
Code Examples:
### Example 1: Blinking LED
In this example, we will use the Arduino Uno R3 Board compatible to blink an LED connected to digital pin 13.
Hardware Requirements:
Arduino Uno R3 Board compatible
 LED
 Resistor (220)
 Breadboard
 Jumper wires
Code:
```c
const int ledPin = 13;
void setup() {
  pinMode(ledPin, OUTPUT);
}
void loop() {
  digitalWrite(ledPin, HIGH);
  delay(1000);
  digitalWrite(ledPin, LOW);
  delay(1000);
}
```
Explanation: In this example, we define a constant `ledPin` as digital pin 13. In the `setup()` function, we set the pin mode as OUTPUT. In the `loop()` function, we use the `digitalWrite()` function to set the LED pin to HIGH (turning the LED on) for 1 second, and then set it to LOW (turning the LED off) for 1 second, repeating the process indefinitely.
### Example 2: Reading Analog Input from a Potentiometer
In this example, we will use the Arduino Uno R3 Board compatible to read the analog input from a potentiometer connected to analog pin A0.
Hardware Requirements:
Arduino Uno R3 Board compatible
 Potentiometer
 Breadboard
 Jumper wires
Code:
```c
const int potPin = A0;
void setup() {
  Serial.begin(9600);
}
void loop() {
  int potValue = analogRead(potPin);
  Serial.print("Potentiometer value: ");
  Serial.println(potValue);
  delay(500);
}
```
Explanation: In this example, we define a constant `potPin` as analog pin A0. In the `setup()` function, we initialize the serial communication at a baud rate of 9600. In the `loop()` function, we use the `analogRead()` function to read the analog input from the potentiometer and store it in the `potValue` variable. We then print the potentiometer value to the serial console using `Serial.println()` and wait for 500 milliseconds before taking the next reading.
### Example 3: Communicating with a Serial LCD Display
In this example, we will use the Arduino Uno R3 Board compatible to communicate with a serial LCD display connected to digital pin 2 (RX) and 3 (TX).
Hardware Requirements:
Arduino Uno R3 Board compatible
 Serial LCD display
 Breadboard
 Jumper wires
Code:
```c
#include <SoftwareSerial.h>
const int rxPin = 2;
const int txPin = 3;
SoftwareSerial lcd(rxPin, txPin);
void setup() {
  lcd.begin(9600);
  lcd.print("Hello, World!");
}
void loop() {
  // No operation
}
```
Explanation: In this example, we include the `SoftwareSerial` library to enable serial communication on digital pins 2 and 3. We define constants `rxPin` and `txPin` as digital pins 2 and 3, respectively. We create a `SoftwareSerial` object `lcd` with the RX and TX pins as arguments. In the `setup()` function, we initialize the serial communication at a baud rate of 9600 and print "Hello, World!" to the serial LCD display using `lcd.print()`.
These examples demonstrate the basic usage of the Arduino Uno R3 Board compatible in various contexts, including digital output, analog input, and serial communication.
