For example, to flash the system LED, the following Arduino program can be used:

void setup() {
    // Initialize the LED_BUILTIN pin as an output
    pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
    // Turn the LED on (Note that LOW is the voltage level
    digitalWrite(LED_BUILTIN, LOW);
    
    // Wait for a second
    delay(1000);
    
    // Turn the LED off by making the voltage HIGH
    digitalWrite(LED_BUILTIN, HIGH);
    
    // Wait for two seconds (to demonstrate the active low LED)
    delay(2000);
}

--- Use NodeMCU with Lua ---

The official NodeMCU firmware contains the Lua Interpreter. Lua is an interactive programming language which allows you to experiment and build simple working programs without a lot of effort. If you are not familiar with Lua, you will find that it is not hard to learn, at least for the simple tasks needed to get started.
