There is a speaker module that can be directly connected to the tokymaker. Tokymaker can reproduce tones. but not mp3 files. However, thanks to IoT, It can reproduce songs or sounds from your spotify or Soundcloud account through IFTTT. You can find more information in our free IoT course in www.tokylabs.com/learn52
Another alternative is to connect a module that can reproduce a certain mp3 file if a high level is received from tokymaker.
