Interactive posters - proximity sensing to trigger audio

Hello everyone,

i am super super new to the forum and to the world of arduino and programming so i was wondering if you could advise me on a project im trying to complete.

I have been experimenting with combining technologies to make interesting new work from printed visuals.

I am looking to create a poster that plays audio when it detects the presence of a person.

i've been using conductive ink for the posters and i have manage to use an arduino to create a basic capacitive proximity sensor when connected to the ink.

i want to move on to the next step which is to make this sensor trigger audio but i have no idea how to go about it or program it. I've figured i need a waveshield which i've purchased and soldered but now i don't know how to go about combining the proximity sensor and the waveshield to trigger audio.

any help would be greatly appreciated as i'm feeling wayyyyy out of my depth here, i have no skills at circuits and programming whatsoever! stressed out :~

thank you
