Size: 45mm x 18mm (1.77" x 0.71")Code Examples### Example 1: Blinking an LEDThis example demonstrates how to use the Arduino Pro Micro board to blink an LED connected to digital pin 13.```cpp
const int ledPin = 13; // Pin 13 for the built-in LEDvoid setup() {
pinMode(ledPin, 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 Analog Input from a PotentiometerThis example shows how to use the Arduino Pro Micro board to read the analog value from a potentiometer connected to analog pin A0 and print it to the serial console.```cpp
const int potPin = A0; // Pin A0 for the potentiometervoid setup() {
Serial.begin(9600);
}void loop() {
int sensorValue = analogRead(potPin); // Read the analog value
Serial.print("Sensor value: ");
Serial.print(sensorValue);
Serial.println(";"); // Print a semicolon for CSV format
delay(50); // Wait for 50ms before taking the next reading
}
```### Example 3: USB Keyboard EmulationThis example demonstrates how to use the Arduino Pro Micro board to emulate a USB keyboard and send keystrokes to a connected computer.```cpp
#include <Keyboard.h>void setup() {
Keyboard.begin(); // Initialize the keyboard
}void loop() {
Keyboard.print("Hello, world!"); // Send the keystrokes
Keyboard.press(KEY_RETURN); // Press the Enter key
delay(1000); // Wait for 1 second
Keyboard.releaseAll(); // Release all keys
delay(5000); // Wait for 5 seconds before sending the next message
}
```These examples illustrate the versatility of the Arduino Pro Micro compatible 5V 16M Mini Leonardo Microcontroller Development Board and demonstrate its potential for various IoT applications.
