Looking for IR devices that can be uniquely identified

Projects General Guidance
1

There are plenty of IR emitter/receiver devices out there, such as a keypad and USB receiver that you can use in your projects.

I'm looking to create a project that can have multiple keypads, each with a unique ID so that multiple people can press a key and that would be detected by the arduino. e.g.

Keypad 1 pressed 6
Keypad 2 pressed 3

etc.

Do you know of any hardware that would allow this?

Programmable remote controls will do what you want.

Else any Arduino with a keypad and IR LED will do as well.

Programmable remote controls will do what you want.

Do you mean I would program Remote 1 so that when someone pressed the "1" key it would send "1 1" and Remote 2 so that "1" would send "2 1"?

Wouldn't they "step" on each other?

Of course the controls should never send at the same time. That's a problem common to all networks.

Any two units sending at the same time will mess each other up!
