How to connect a 7-segment display with logic gates

Who does not have in his disaster drawer, a set of LED display with two, three or four digits. This is the moment to reuse this display (multiplexed) in a counter whose application can improve a presentation that was pending. In this article, we will see how to apply code to a multiplexed display and how it should work.

This example, shows an improved code to the one represented in the first example. As can be seen, I have used the same Arduino pins in each example. With this, I try to minimize the assignment errors in the different code listings.

The problem that the programmer may encounter, facing a multiplexed representation, lies in the sampling times of each digit, for this reason, I recommend that you take into account, I would say, very much into account, not to use or minimize the delay(), since they tend to produce the effect of "flickering" that is seen in the digits.

In a multiplex, there will always be a flicker, even if it is not very noticeable, the more digits are displayed, the more evident it will be. For this reason, sampling times should be reduced as much as possible.
