To turn a port high, use this command:

PORT{letter} |= _BV(P{letter}{number});

To turn a port low, use this command:

PORT{letter} &= ~_BV(P{letter}{number});

Replace {letter} and {number} with the corresponding pin letter and number. For example, for pin B5 with the LED, turning it high and then low would be:

PORTB |= _BV(PB5);

PORTB &= ~_BV(PB5);
