// the setup function runs once when you press reset or power the board
void setup() {
// 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)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW

For digispark ATtiny85

void setup()
{
//Set Pins 0 and 1 as outputs.
//Some Digisparks have a built-in LED on pin 0, while some have it on
//pin 1. This way, we can all Digisparks.
pinMode(0, OUTPUT);
pinMode(1, OUTPUT);
}
void loop()
{
//Set the LED pins to HIGH. This gives power to the LED and turns it on
digitalWrite(0, HIGH);
digitalWrite(1, HIGH);
//Wait for a second
delay(1000);
//Set the LED pins to LOW. This turns it off
digitalWrite(0, LOW);
digitalWrite(1, LOW);
//Wait for a second
delay(1000);
