Input Voltage: 7-12V
Digital I/O Pins: 14
Analog Input Pins: 6
Flash Memory: 32KB
SRAM: 2KB
EEPROM: 1KBCode Examples### Example 1: Blinking an LEDThis example demonstrates how to use the Arduino Uno R3 Original to control an LED. The code will blink an LED connected to digital pin 13 at a rate of 1 Hz.```c++
const int ledPin = 13; // Pin 13 for the built-in LED on most Arduino boardsvoid setup() {
pinMode(ledPin, OUTPUT); // Set the pin as an output
}void loop() {
digitalWrite(ledPin, HIGH); // Turn the LED on
delay(1000); // Wait for 1 second
digitalWrite(ledPin, LOW); // Turn the LED off
delay(1000); // Wait for 1 second
}
```### Example 2: Reading an Analog SensorThis example demonstrates how to use the Arduino Uno R3 Original to read an analog sensor, such as a potentiometer or photodiode. The code will read the analog value from pin A0 and print it to the serial console.```c++
const int sensorPin = A0; // Pin A0 for the analog sensorvoid setup() {
Serial.begin(9600); // Initialize the serial console at 9600 bps
}void loop() {
int sensorValue = analogRead(sensorPin); // Read the analog value from the sensor
Serial.print("Sensor value: ");
Serial.println(sensorValue); // Print the value to the serial console
delay(100); // Wait for 100 ms before taking the next reading
}
```### Example 3: Serial Communication with a PCThis example demonstrates how to use the Arduino Uno R3 Original to communicate with a PC over a serial connection. The code will send a string "Hello, World!" to the serial console at a rate of 1 Hz.```c++
void setup() {
Serial.begin(9600); // Initialize the serial console at 9600 bps
}void loop() {
Serial.println("Hello, World!"); // Send the string to the serial console
delay(1000); // Wait for 1 second before sending the next message
}
