LED Blink

Solving Approach

How do you plan to solve it?

 connect resistor with 320 ohm, in series with LED with voltage drop of 1.8V.

then write following code

void setup(){

pinMode(4,OUTPUT);

}
void loop(){

digitalWrite(4,HIGH);

delay(400);

digitalWrite(4,LOW);

delay(800);

}

Code

/*Paste your code here*/
void setup(){

pinMode(4,OUTPUT);

}
void loop(){

digitalWrite(4,HIGH);

delay(400);

digitalWrite(4,LOW);

delay(800);

}
