I am working on a project for my job that is just a simple door bell that says "welcome " when a door is open.
So the main operation is this.
When conditions are met a relay will trip.The relay will close and provide PIN1 to ground on my ADAfruit MINI fx board that has been loaded with a wav file that says welcome to our home.
The audio will be ran through an amplifier and then through hidden speakers.
Pretty simple.
Well i received my FX board today and found out that it needs some modification to work.
If i momentarily close the circuit(pin 01 to ground) it will play the audio file once and stop. (exactly what i want)
If the circuit is closed for longer than the WAV file is, it repeats. (I leave the door open and it says welcome welcome welcome welcome until i close it)
I cant get any help from the people at ADAFruit some im coming here.
My needs.
I need to take a constant 12v and have it close a contact for 1-3 seconds and then release so even if the 12v signal is there for 5 minuites, the fx board will only play the wav file once.
Any thoughts?
Additional info
I also have one of these but i don't think it will help.
