My project, as best as I can describe it, is a wack-a-mole. The point is that when you see a certain output, such as an LED, you make an input right beside it, such as pressing a button (I'll also include things like slide switches, RGB's, light sensors, etc.). How it'll work is that an LED will have a 50% chance of turning on (I've already got that part down), then, if you press the button next to it , you keep going, but if you press it while the LED is not on or you don't press it within a certain time limit, you lose and the game is over. After I get help with this part, all I have to do is adapt it to other inputs and outputs. I've been searching for a while now and I can't find any answers, I'd really appreciate the help!
Start with the BlinkWithoutDelay example.
See if you can get one button to respond properly while the single LED is on. (Use Serial or another 2 LEDs for win/lose.)
