Electronic Response Board

I run escape rooms and I am looking for someone to build me a puzzle/game.

I need someone to build me a physical board that contains 12 buttons, all linked to the web. The buttons will need to flash randomly and the person playing will have to touch the buttons within X seconds. If they get to the button in time, they will score a point - if they get enough points, a video will start to play

The board will need to be 1m x 2m in size and ideally be both battery and mains powered.

The successful person will be able to advise on the best (and cheapest) buttons and sensors, and manage the programming to ensure the clicks are registered online. This project could suit two sperate people.

If you are interested please contact me and we can discuss.

Thanks very much
Ian
