Prototyping a connected piggy bank - Repost

I saw this today and figured it would be a shame if it was not shared on this forum considering it’s using a Particle Photon for it’s web connectivity.

In this article I will explain how I made a prototype of a talking piggy bank that connects to an online bank account. I’ll explain how it works and the process I went through; I’ll discuss how it progressed from an ‘interaction’ prototype to an ‘experience’ prototype and how I used the Monzo API to do so.

connected to an online bank account. Here’s a quick video explaining it

If you can’t watch the video, here’s another explanation of what it does.

Doh’ just noticed that’s just a repost, so I’ll have to ask that on the original source :blush:

Nice work :+1:

One question about the MP3 player: Does this module do any “heavy lifting” in converting the numbers on bord or are you just breaking up the number on the Photon and play individual MP3 files in sequence?

The reason for the question is, if this would also be a job for the much cheaper modules with included amp like these,searchweb201602_2,searchweb201603_1&btsid=742a1c33-3672-4bd7-b57c-bd57e4809303
