Answer
The digitalWrite() function is used to control the state of a digital pin on the Arduino microcontroller. It is used to send a HIGH or LOW signal through an output pin.
- HIGH means the pin outputs 5 V (ON)
- LOW means the pin outputs 0 V (OFF)
Syntax:digitalWrite(pin, value);
Where pin = digital pin number, and value = HIGH or LOW.
Example:digitalWrite(3, HIGH);
will send a HIGH signal through pin 3
