The amplifier is a PAM8403 chip based design, Arduino compatible. Components and wiring diagram of the Music Machine. This makes it easy to replace these devices in case of malfunction.ДЇigure 2. I have chosen to mount the Nano, MP 3 player and the auxiliary power supply onto female pin headers that are soldered on the base board. Figure 2 shows the components and the general wiring diagram. The speakers (not shown in figure 2) are plugged with male jack connectors into the female sound outlet jacks soldered onto the base board. All these components, except the speakers, are mounted on a base soldering board with dimensions 120Г—85 mm (43Г—30 perforations). The Music Machine described here has the following five main components: Arduino Nano, MP3 player, stereo amplifier, speakers, and auxiliary power supply. The card reader fully supports the FAT16 and FAT32 file systems. This MP3 player is, for its low price, quite a performer. Pin layout of a stereo mini-SD card MP3 player for Arduino.

That makes a total of 2,550 pieces of music!ДЇigure 1. The amount of music controlled is 100 folders each containing up to 255 songs (maximum supported capacity is a 32 GB SD card). Output is to an earphone (SPK_1, SPK_2, see figure 1) or an amplifier (DAC-R, DAC_L).

The MP3-TF-16 MP3 player is a versatile, low cost device that can be operated standalone or with an Arduino, with two-channel (stereo) output under software volume control. Here we experiment with a 16 GB micro-SD card and a MP3-TF-16 MP3 player that is equipped with a SD card slot. These are cheap and they offer gigantic amounts of storage. A popular external storage device is the SD card. A solution is as old as computer science: use external storage. Playing music is not directly possible because even a short stereo music track in MP3 format has a size of close to 2 MB, or far too much exceeding the amount of memory available in the Uno or Nano. At the same time it limits what can be achieved with this microprocessor board. Memory constraint is nevertheless a charming aspect because it forces the user to be very efficient and creative with programming.

The ATmega328 chip has a minuscule 32 kB of addressable RAM memory available plus 2kB of SDRAM. The Arduino Uno and its little brother Nano are microcontroller boards equipped with a very limited amount of on board memory. A connected PAM 8403 mini amplifier powers two mini speakers.

Here we discuss a Music Machine consisting of a simple stereo MP3 player that is controlled by an Arduino Nano. Connecting a SD card based MP3 player to an Arduino overcomes the memory limitation and opens the world of real digital audio. If (!myDFPlayer.Because of working memory space constraints in Arduino microcontroller boards, production of sound with these boards is normally limited to creative application of beeps.

Here is the code I am using: #include 'Arduino.h' Anyone had similar problem? I just want it to play all files in a loop in random order. I also tried with Nano V3 Atmega328 CH340 but no luck there. I have it connected like this: connection with arduino uno. The problem is when I am trying to use mp3-TF-16P with the same code as DFPlayer, it only flashes power light for a quick second and produces some weird struttering like sound. I tried with DFPlayer mini which is suppose to be the same as mp3-TF-16P and I got it to work.
