I'm thinking of building an experience which allows a user to learn more about a physical object by pressing an adjacent button. Upon press, a TV will play a video describing the piece in more detail. Think of a large wall of posters (each with their own button) with a shared screen in the middle. These posters must be quickly interchangeable so a wireless solution is a must. Also, the transmitting device should run off a battery and be inexpensive.
I've used Bluetooth LE in the past and am confident I can easily use something like http://www.blueradios.com/hardware_sensors.htm or https://store.ti.com/cc2650stk.aspx to accomplish my task. But at ~ $30 a pop, that's getting to be an expensive project.
I think I'd like to try RF transmitters and receivers (https://www.sparkfun.com/products/10534, https://www.sparkfun.com/products/10532) but I'm not sure if they're the right fit for my project. In the given examples for each product, it looks like both the transmitter and receiver require a micro controller. Is it possible to use the transmitter without a controller and still produce a unique signal for a receiver?
Thoughts? Any other approaches?
