Hello, Ben!
I have a challenge for you to build. Don't you sometimes want to play hide and seek, but you don't have a good (or any) opponent? I think you should create a device that is able to drive around on the floor inside and avoid objects by using an ultrasonic (PING)))?) sensor. It would also have a GPS onboard. The player would have a small device with red and green LEDs (as well as another GPS module), and it would direct you with hot and cold until you are within a small radius of it. When you find it, you tap the reset button on it and play again!
Thanks!
