/**
* @brief Simple example to read two digital inputs using ESP32
* @details This program demonstrates how to read two digital input states
*          from GPIO16 and GPIO17 of an ESP32 development board.

// Define the GPIO pins for digital inputs
#define INPUT1_PIN 16  // GPIO16 for Digital Input 1
#define INPUT2_PIN 17  // GPIO17 for Digital Input 2

void setup() {
    // Initialize the serial communication for debugging
    Serial.begin(115200);
    Serial.println("ESP32 Digital Input Read Example");

    // Set the input pins as INPUT
    pinMode(INPUT1_PIN, INPUT);
    pinMode(INPUT2_PIN, INPUT);
}

void loop() {
    // Read the state of the digital inputs
    int state1 = digitalRead(INPUT1_PIN);
    int state2 = digitalRead(INPUT2_PIN);

    // Print the states to the Serial Monitor
    Serial.print("Digital Input 1 State: ");
    Serial.println(state1);
    Serial.print("Digital Input 2 State: ");
    Serial.println(state2);

    // Wait for 500 milliseconds before reading again
    delay(500);
