FA15 Arduino IDE

digitalRead() is used for:

• Reads the value from a specified digital pin

• Writes an analog value to a pin

digitalWrite(13, LOW);

• Turn off LED at Pin 13

• Turn on LED at Pin 13

digitalWrite (13, HIGH);

• Pressed the switch button

• sets the digital pin 13 on

pinMode(7, OUTPUT);

• sets the digital pin 7 as output

• Turn on LED at Pin 7

delay(1000);

• Wait for 1000 seconds

• Wait for 1 second

When you set a digital pin to HIGH, its voltage will be set to:

• 5V

• 0V

digitalWrite(X, Y)..... what is X

• pin number

• HIGH or LOW

digitalWrite(pin, value).... the value could be:

• UP or DOWN

• HIGH or LOW

Is the command correct: digitalWrite(HIGH, 8);

• correct

• wrong

delay(X)... what is X

• the number of seconds

• the number of milliseconds
