Here's my version of the classic Rock-Paper-Scissors game, but it's just you against the ATMEGA328P-PU. The scorekeeper is across the top with a yellow LED for even, green LED's for the player, and red LED's for the chip. If one side gets 5 up on the other, the scorekeeper flashes for the winner. The middle Rock-Paper-Scissors LED's indicate each side's play. For now, the micro tries to just randomly pick a play, but the plan is to have it reading my mind down the road.
The version I built here is a stand-alone board, but I used the Arduino software for programming and the game can also be built using an Arduino UNO board.
