Principle of Work:

The ESP32 NodeMcu uses a combination of a dual-core processor, various interfaces (UART, I2C, SPI), and wireless modules (WiFi/Bluetooth) to perform tasks while maintaining low energy consumption. When powered on, the microcontroller executes the program stored in its 4MB flash memory, controlling the connected peripherals and communicating with other devices.

Code Example (Blink LED):


void setup() {
  pinMode(LED_BUILTIN, OUTPUT);  // Set the built-in LED as output
}

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);  // Turn LED on
  delay(1000);  // Wait for 1 second
  digitalWrite(LED_BUILTIN, LOW);  // Turn LED off
  delay(1000);  // Wait for 1 second
}
