int led1 = D2;

void setup() {
    pinMode(led1, OUTPUT);
}

void loop() {
    digitalWrite(led1, HIGH);
    
    delay(3000);
    
    digitalWrite(led1, LOW);

int led1 = D2;

void setup() {
    pinMode(led1, OUTPUT);
}

void loop() {
    for(int i = 0; i < 5; i++) {
        digitalWrite(led1, HIGH);
        delay(500);
        
        digitalWrite(led1, LOW);
        delay(500);
    }

int led1 = D2;
int led2 = D3;
void setup() {
    pinMode(led1, OUTPUT);
    pinMode(led2, OUTPUT);
}

void loop() {
    digitalWrite(led1, HIGH);
    digitalWrite(led2, LOW);
    delay(500);
    digitalWrite(led1, LOW);
    digitalWrite(led2, HIGH);
    delay(500);
