I want to create a handheld clicker/lever, that when activated or "clicked" will "score" a point, displayed on a smart phone/tablet's scoreboard app.
There would be 2 players, each with a handheld clicker/lever device, and they would be competing on scoring the most points, within a limited, specified time. The handheld clicker/lever device would be connected to the smartphone/tablet via Bluetooth.
Any Ideas? I am a computer hardware guy.
