So i'm working on a project. It's basically a quiz. 1 question and 4 possible answers.
There will be a max of 10 players. Everyone of them has a "controller" with 4 buttons. A yellow, green, red and a blue button. Let's say the first question appears. Player 1 presses the Button1.
I've already coded everything besides the input. I couldn't find out, how i can get the input from a controller. I've seen that it could be possible with I2C. I went on some forums and searched on there but the questions were 10 years old, so it was kinda outdated and wouldnt work.
Hopefully there's someone that can help me with this!
