Hey guys, how are you? Hope fine. I'm trying to activate a button of a mp3 player with Arduino. Well, the main idea is very simple, just make a short with 2 wires in a tiny period of time to "simulate" a button pressed (the mp3 player has a smd pushbutton where I soldered 2 wires to make the short)…
