I'm using arduino nano board, and I'm trying to play two different music simultaneously. One dfplayer has to be controlled by a touch sensor, and another dfplayer will be controlled by the distance sensor. But I don't know how to connect 2 dfplayers with the nano board. Now I connected one dfplayer.
