Web\$\begingroup\$ You are not passing the port as a parameter, so this isn't relevant. Passing a port as a parameter is when your function doesn't know which port to write to (PORTD, PORTB, PORTC, etc), and the port is passed as a parameter to such function.You are trying to pass the value to write to the port. Like others have said, make sure that DDRD is set …
