### Default Sketch

The default sketch loaded on the Nano ESP32 board is found in the code snippet below:

```arduino
#define LEDR 46
#define LEDG 45
#define LEDB 0
#ifdef LED_BUILTIN
#undef LED_BUILTIN
#define LED_BUILTIN 48
#endif

void setup() {
// put your setup code here, to run once:
pinMode(LEDR, OUTPUT);
pinMode(LEDG, OUTPUT);
pinMode(LEDB, OUTPUT);
pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
digitalWrite(LED_BUILTIN, HIGH);
digitalWrite(LEDR, LOW);
digitalWrite(LEDG, HIGH);
digitalWrite(LEDB, HIGH);

delay(1000);

digitalWrite(LED_BUILTIN, LOW);
digitalWrite(LEDR, HIGH);
digitalWrite(LEDG, LOW);
digitalWrite(LEDB, HIGH);
