I need Control DIY MP3 player with just 2 buttons on wires. One button function shouls Play and Pause. Another button is Next /Previous track.

Hello, I am an electronics and telecommunication engineer and my major is wireless systems' design. I am experienced in hardware and embedded systems' design. I have designed/printed/tested many PCBs and I am quite experienced with RF design such as designing antennas, matching networks(distributed/lumped elements), filters(distributed/lumped elements), power amplifiers, dividers, feed networks, differential pairs/signals, EMI, clearance areas, shielding for EMI, conducted interference, common mode, etc, LVD, high speed data communication. I have checked your requirements I am quite sure that I can help you with your project. Just give me all the details and I will do my best to help you. Best regards

Hello, I can help you to make DIY MP3 player. I have experience working with TF card based MP3 player device.

Greeting, Thanks for posting the project there i am electronics engineer I have expertise in embedded systems and designing of portable audio devices. I understood the project description you want to design an MP3 player, we can use analog IC or micro controller to develop the device as per your requirements. I know how to develop the best quality and cost effective solution, contact with me for best services at affordable rates. Best Regards Muhammad Adeel

Here is my past experience. - Multilayer PCB design and flexible board design, BOM design. - Firmware C/C++ (ARM, Arduino,ESP32, PIC) - AC/DC DC/DC converter and power converter, power circuit design - Experience with ARM, MCU, Arduino, Raspberry Pi - USART, USB, SPI, I2C, RF, RS232, BLE communication module design - Motor control, LED lighting design, camera module design - Artistic form design and quick error correction ⁃Experience in PCB design verification such as prototyping and practical knowledge of FCC certification ... I am fully focused on your project and look forward to doing your best. I would like to have a specific discussion with you about the details of the project. regards

Hi, I have created a product using a mp3 module called "DFPlayer Mini" and ATMEGA328. The module is controlled through Serial (TTL). It is possible to have a more advanced control including EQ(Rock/Pop/Jazz etc) with minimal wiring. The module can also be controlled through buttons without the need for a MCU. The downside is that the module lacks a 3.5mm audio jack. My proposal is to use the module along with an Arduino with buttons and LCD to implement all your requirement.
