Alright... Paul referred in his PM to the XY Problem, so let me start from the beginning.Problem X: For my project, I want to use a large (~6cm) 4 digit display, preferable 7-Segment. I'm using already 12 of the digital pins of the Arduino for inputs.
What is the application that uses 12 inputs of your UNO?
