Or use the "columnspan" option in the call to grid for the button:

tk.Button(self, text='Turn On', 
command=self.led_list[1].turn_on).grid(row=3, column=2, columnspan=2, 
padx=5, pady=5)

I was lazy and looked this up in my very old Tkinter book. But I can't 
imagine that this option might have vanished or changed its name. 
Probably all GUI libraries know it. Of course there is also "rowspan".
