In this video, I show you my approach to making a rotary encoder module. One can buy different rotary encoder modules on Aliexpress for a very cheap price, and I have been doing that for years, too. However, I wanted to come up with my own version of such a module. Typical modules either only contain some pull-up resistors, or they even have RC low-pass filters, but I haven’t encountered any that have a built-in Schmitt trigger circuit that allows to produce perfect square waves.
