How to make Mp3 Player
Today quote: “My life is my message” – Mahatma Ganhi
Two weeks ago, I posted How to make Mp3 Player with DFPlayer. Today I posted same topics with different module which is named JQ6500-16p. JQ6500-16P has an onboard 16Mbit (2 MMegaByte Flash memory. Using Windows operating system you can upload MP3 very easily. Software is embeded with module so that, don’t need download any software
JQ6500-16p
Bellow images show Pinmap of the module.
| PIN | Function |
| K1 | Hotkey to play 1st File |
| K2 | Hotkey to play 2nd File |
| K3 | Hotkey to play 3rd File |
| K4 | Hotkey to play 4th File |
| K5 | Hotkey to play 5th File |
| NXT/VOL+ | Press to play next file; Hold down to increase volume. |
| PRV/VOL- | Press to play previous file; Hold down to decrease volume. |
| PL/PAUSE | Pauses or Resumes the currently playing file. |
| SRC | Changes the file source, from on board memory to the SD Card (28p model only). Note that the source defaults to the SD Card if it is inserted, if not it will fall-back to the on board memory. |
You can check capabilities of DFPlayer with this website.
You can control the module with K1-4 and ADKey pins. Bellow images shows the how to control with ADKey pins.
Embedded Software
When you plug USB to computer. Computer sees module like CD.
When you opened it. Software is open. Software language is Chinese but using of software is very easy. Software have two tab first of them is upload selected mp3. Second is selecting files.
Bellow figures how to upload works.
Work with Arduino
Also you can control with Arduino using TX/RX pins. You can download library from here
To use this library with a 5v Arduino, connect as follows.
| JQ6500 Module | Arduino |
|---|---|
| RX | through a 1K Resistor then to pin 9 |
| TX | pin 8 |
| GND (any of) | GND |
| VCC (any of) | VCC |
To use this library with a 3v3 Arduino, connect as follows…
| JQ6500 Module | Arduino |
|---|---|
| RX | pin 9 |
| TX | pin 8 |
| GND (any of) | GND |
| VCC (any of) | VCC |
You can use pins other than 9 and 8 if you wish, simply set them in your code.
