I'm working on a project where audio messages will be played back and colored LEDs will match the message. The audio playback and LEDs will be controlled via RF and/or wired buttons. My issue is that I need the relays to latch on with the button, but I also need to make sure that only one is on at a time. For example, the push button panel will have 3 buttons, and each of those buttons will be a different priority. In case the wrong button was pressed, or the priority level changes, I only need one output on at a time. The wireless receivers I am using will latch no problem, but have no control over only one output being on at a time.
