MCVE Sketch
// the setup function runs once when you press reset or power the board
void setup() {
Serial.begin(115200);
Serial.println("aa");
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
Serial.println("HIGH");
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
Serial.println("LOW");
delay(1000); // wait for a second
