I have a new project I’m starting and I’m having some similar issues as in a previous project. I’ve designed the circuit based on the good advice I received on the other project but I’m having similar issues.
The main difference is that I’m now using a 4-digit 7-segment display (cathode) instead of a 2-digit. It’s still being controlled by a max7219 and the LedControl library.
I’m getting flickering reading from my pot by only about 1 digit, but I’m reading out the results on the display which caused flickering on the display as well which is no good.
