Loop through Cells C3:C33 to get this code to run continuously so I can run a macro when I input into any of these cells?

Question

So I want to run a macro when I select something from a drop down list in each of the cells C3:C33. I have gotten thus far with the code and it works for just one cell (C3 as shown below). I can't figure out how to continuously loop form C3 to C33 so that my Macro will run when I change any of those cells.

    Private Sub Worksheet_Change(ByVal Target As Range)
    myCell = "C3"
    If Not Intersect(Target, Range(myCell)) Is Nothing Then
        Select Case Range(myCell)
            Case "IB-16": Input_Open
            Case "OB-16": Output_Open
            Case "IF-8": AI_Open
            Case "OF-8": AO_Open
        End Select
    End If
    End Sub
