Here is the reason why the 7 segment indicator with TM1637 controller does not work

I bought some displays with TM1637 controller from Aliexpress, but there was a bug in them that made these displays not work. In this video I explained how to fix this bug. Once the error has been resolved, all displays work fine.

These displays can be purchased from the links below. These 7 segment display modules come in different colors and sizes (mostly 0.56" and 0.36" diagonal). The 4-digit modules also differ in that some may include a colon (for clock seconds) and others may include decimal points, although it is not always written in the product description.
