Interactive poster

Hi all,

I'm brand new to this site & know nothing much about electronics and only a little bit more about coding.
What I do know is that I'm a senior secondary science teacher with a really tough crowd this semester & need to try something new and engaging.

I want the students to make an interactive poster that will play audio when parts of the poster are touched. There will be 5/6 different interactive elements, each with a different audio explanation.

So I need a list of kit I am going to need, here's what I've got so far:

Arduino (which one?)
capacitive sensors (any recomendations?)
Conductive tape or wires?

Do I need anything else?
Where will the audio files be stored?
How will I power the thing? I'd like it to be as cord-free as possible.

Any help will be gratefully received!

Something like this to play wave files from the SD card. Adafruit Wave Shield for Arduino Kit [v1.1] : ID 94 : $22.00 : Adafruit Industries, Unique & fun DIY electronics and kits

This one board will do everything you need. Not cheap but it will work and do what you want with the minimum of complications.

That's (TouchBoard) a really good solution, Mike. Thanks for finding that...

The "usual" solution includes the components of the Touch Board:
An Arduino (Like UNO),
an Audio Playback board like the Adafruit one,
and a capacitive touch module.

You could save a little money with DIY. And maybe learn more about Arduino.

Absmann, send me an email and I may be able to help out with a few things for your classroom.

They did a kick starter a few years back. I was blown away by the quality of what they produced.

I met the guys at about 6 Maker shows and got to know them, they are a great enthusiastic bunch.

Thank you so much for all your replies. I will check all this out right no. :slight_smile:
