I'm new to Arduino's. This is my first project I have done with them. My friend and I are making a tabletop hockey game. We want to create a scoreboard that has several different aspects to it that are vital for the way our game is played. I can't seem to understand how or if it is possible for us to jam all of these things into a single Arduino Uno. I used a shift register for all the buttons that we have. I have most of the programming done and all our numbers are showing up correctly in the serial monitor.
I'm mostly worried about the 7 segments taking up too many pins on the Arduino and running out of room. I know I can use a shift register for the 7 segments, but can I daisy chain a ton of 7 segments with shift registers and have them display completely different unrelated outputs?
We have four 7 segment LEDs, two 2 digit 7 segments LEDs, a 2 digit 7 segment LED with a positive or negative sign, and then a single basic red LED.
There are a total of six different outputs that need to be displayed. Three of the regular 7 segments are going to be used for the same output.
Let me know what you think and let me know if I can clarify anything better.
