Hello, I am revisiting these forums after almost a decade of being away. Had to create a new account. It’s good to be back!
I am embarking on a new Arduino project. It is a simple, portable piece of interactive art.
Essentially It’s a box with three lights on top. Inside the box will live a portable battery, the Arduino, and any wireless communication hardware.
The desired effects?
Either via RF, Bluetooth, NFC, or RFID, the box is able to have a light go dark. Think of it like tag. If someone carrying or pressing the right emitter is nearby the box, a light goes out. This can happen in sequence until all the lights go out.
The goal is to use hardware that can affect the box from 5-10 feet away. But no further than that. We will have a few of these boxes in use at the same time and accidentally affecting all the boxes in a large room at once would be an undesired effect.
Bring the box to a “recharge” point and you can add a light back. But that recharge point won’t add another light to the same box for a time limit of 90 seconds. This can likely be achieved by using some kind of transmitter with a unique ID, and writing instructions for the Arduino that prevents it from recharging again from that unique ID for a span 90 seconds.
I hope this all makes sense.
What hardware do you suggest to pull this off? The trick is wireless communications that don’t affect the box from far away, as this will be used as an interactive art installation that requires closer contact.
