After stumbling onto some abandoned company's warehouse, you fill an old crate to the brim with pre-AI era technology from their company museum. Time to check if this stuff even turns on anymore.
"It looks like inventr.io built a museum here displaying the products that the company produced. It's complete with working samples of the pre-AI microcontrollers that made the company famous along with everything necessary for visitors to try them out, including different laptop computers of the day showing the different operating systems that pre-AI computers used to run.
Check out this display. It has a bunch of working HERO XL boards, an early (pre-AI!) inventr.io microcontroller. Being pre-AI, we can safely use these to make our life easier in our new home. Let's take a closer look at these."

Blink
Turns an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino
model, check the Technical Specs of your board at:

// the setup function runs once when you press reset or power the board

// initialize digital pin LED_BUILTIN as an 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
delay(1000); // wait for a second
