When I have something I have to remember (a bill to pay in a few weeks for instance) I put it in a prominent place on the pinboard above my computer.
如果有我需要记住的事情，例如过几周就要偿还的账单，我把它放在我电脑上插针板的显著位置。

Note that you can employ the structure in Table 3.1 independently of your product backlog tool, for instance, by appropriately arranging paper CARDS on a pinboard, whiteboard, or the office wall.
Most Arduino boards already have an LED attached to pin 13 on the board itself. If you run this example with no hardware attached, you should see that LED blink.
