I am considering a project for my gf.
She is a teacher, and saw a project with 6 wireless buzzers, when pressed the buzzers a light tower indicates with a color scheme what buzzer was pressed first and what buzzer was pressed second.
I want to built something similar (I am not sure if the final project will use Arduino or a simple microcontroller for price saving).
Currently I want to use arduino for prototyping.
Upon investigations I saw this modules 433MHz transmitter-receiver pair: https://www.ebay.com/i/392145706685?chn=ps
That I think it could work for what I want to do, but what I am worried since I am not familiar with RF is:
- How to determine what buzzer was pressed first
- Since it is likely that 2 or more buzzers will start transmitting withing a short time difference how to deal with the interference that they will make with one another.
I am open to suggestions.
Also if you know of any nice type of push button that I can use for the project I am open to suggestions as I am used to work with pcb mounted push button.
