Let’s Get Started..
Blinky is the “Hello World” of Physical Computing
How do we implement this?
Digital Output
Three functions to know…
| theme | Confluence |
|---|
pinMode(pin, INPUT/OUTPUT);
ex: pinMode(13, OUTPUT |
|
);
digitalWrite(pin, HIGH/LOW);
ex: digitalWrite(13, HIGH);
// NOTE: -> functions are CASE-sensitive |

Note: The block above corresponds to digitalWrite(pin, HIGH); inserted into loop(). pinMode(pin, OUTPUT); will be inserted into setup() automatically. |

pinMode(13, OUTPUT);
}

void loop() {
digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(13, LOW); // turn the LED off by making the voltage LOW

Instead of using  Image Addedit is fine to use  Image Addedfor pin 13. |
