In a nutshell, I am trying to change the voice of toys to a different language.
There are many toys I am hoping to change, but I am looking to re-purpose the:
- Battery pack (often 3x AA batteries)
- Built-in speaker
- Inputs (buttons, switches)
I have been able to use a few different modules from sparkfun and aliexpress, which essentially do the same thing:
For other toys which have more conditional inputs (like this seat or this book) I was hoping to use a DFPlayer, arduino and communicate over serial with the digital pins to allow for the conditional statements.
*If (page 1 open) && (button 2) then play AudioFile1.wav
A few challenges with this project are:
- Battery life of a dfplayer (3xAA batteries wont last hours, let alone weeks or months of shelf life)
- Max size of a inputs (by my count, i'd have 36 button pushes for that book and over 110 audio files)
Before I go too far, I thought I would throw it out there to see if anyone had any ideas to limit the power consumption of this setup and utilize a better method of inputs.
