Nút Yes No - Mô hình in 3D

Quick one day build, this is a yes no button.  Runs on 3 AAA batteries and a DFPlayer module, so you can load up any mp3 files.  

I made mine from spare parts and I encourage you to do the same.  However, here is the list if you want want like mine.

Printing:

Print using the .3mf file.  The .scad and .stl have the main shape and battery holder fitment, but I was lazy and did the inner negative volumes using PrusaSlicer.

Assembly and Wiring:

DFPlayer Wiring: https://wiki.dfrobot.com/DFPlayer_Mini_SKU_DFR0299

Both of the buttons are wired to the ADKEY1 and GND, with one button using 3.3K in series.

Name your mp3 files 0001.mp3 and 0002.mp3 and copy to the sd card.

• Button 1 - ADKEY to ~0K to Ground = PLAY 0001.mp3
• Button 2 -ADKEY to ~3K to Ground = PLAY 0002.mp3

Use your solder iron to melt a quick hole for the battery wires.
