Okay I'm not talking about the fly toaster on the computer monitor. Sorry if I mislead you but I didn't know how to phrase it correctly. I recently build a game for my son, a "Simon says" machine. It's an interactive memory game with push buttons, led lights and a speaker. You know what I'm talking about... It works great for young kids. So here is my question, I been trying to find a way to have it so that after 3 mins of inactivity, it goes into a 'screen saver' mode. Perhaps a looping LED light show, a perfect night light for my 4 yr old son. I been doing some searching but I can't seem to get a grasp on what I need to do. I appreciate it if someone can point me the right direction.
By the way, I used the sketch from: http://www.instructables.com/id/Arduino-Simple-Simon-Says-Game/
Thanks in advance!
