I wanted to see if someone could point me in the right direction regarding a project me and my son are starting. Basically, we want to do a Reaction test game similar to what they use in sports.
Link to game here - https://youtu.be/aHcZ9_M1o-A?t=95
We've tried to do the simple ones using Raspberry Pi GPIOs, but with this game, we have 24 arcade buttons that light up. And from my understanding Raspberry Pi 3 B+ only have 28 GPIOs, so if I use these and need them to light up individually, I don't have enough GPIOs.
So we were planning to use the GPIOs to trigger the LED light inside each button and then use a Zero delay USB joystick encoder ( We've built a Retro Pi using these encoders before so I know they can work), like these https://www.ebay.com.au/itm/Zero-Delay- ... Sw6VRaNUSm to register the button presses.
So my questions are:
1. Would this solution work using the USB encoder?
2. Are there any similar projects around that we can jump off from?
3. Are there any special drivers or libraries to use a Zero delay joystick USB encoder if I build this in Python?
Any info would really be appreciated.
