I am making a simon says game using an arduino and I found this code off of the internet that I wanted to use. I have already tweaked it some to add another LED and I am wanting to make the game have an easy mode and a hard mode. The easy mode will happen when any other button besides red is pushed and hard mode will happen when red is pushed. I feel like its really easy to change but i cant seem to figure it out. The delay I wanted for EASY MODE is to be 10 seconds between each button pushed and HARD MODE I wanted it to be around 3-5 seconds.
