This article describes the Monitor Pin Detector (74HC245). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components:74HC245. 

To monitor the pins of the chip without any load I put on two
74HC245 integrated that drive the LEDs. In this way I view the states of
the inputs and outputs with no load or resistance with LED, which is
useful if you use the analog inputs. This circuit is not strictly
necessary but it allows me to avoid check the status of the pins with
the ‘scope, all works’ more than comfortable
