I have this board and it wors standalone ok.
Only the volume of the sound is very soft. How can i change the volume of this card ( output is 3,5mm )
Hello, and thanks for your post!
There are three ways you can adjust the volume on the MP3 Trigger.
The first option is the easiest but if you don’t get enough volume from that, the third option would be your only other choice. (The second option isn’t any louder than the first.)
We don’t have instructions for adding your own external amplifier but the first two options are covered in the hookup guide that you can find at the link below.
How do you access the INI file. I am new to this and I have a SparkFun Qwiic MP3 Trigger. I want to increase the volume. Do i need an Arduino board and the software to reprogram ny SparkFun Qwiic MP3 Trigger?
Please see the hookup guide linked above.
How do I physically connect my Quic MP# trigger to an SparkFun RedBoard - Programmed with Arduino. I want to change the vol of my mp3 and bought an SparkFun RedBoard - Programmed with Arduino to do that, but how do I connect them?
The hookup guide is lacking in many areas and does not tell you how to hook the SparkFun RedBoard - Programmed with Arduino to the MP# trigger, nor does it say what to use in Arduino to identify the board, as there is no Arduino uno in my list.
Very confusing and not helpful to say, refer to the hook up guide.
Hi kenan01.
Sadly we don’t have step by step directions on how to connect the MP3 Trigger to a RedBoard or Arduino and I can’t give you step by step directions here.
It takes more than just connecting the two boards together to make anything happen. You need to write your own software utilizing the serial control protocol in the hookup guide to change the volume. How you write the software would determine how you connect the boards together.
At a minimum, you would be connecting both boards ground pins and then transmitting serial data from the RedBoard/Arduino from a pin and connecting that pin to the RX pin on the MP3 Trigger. You would need to write your software to send the correct command for raising volume and summary of the commands is in the hookup guide. Unfortunately we can not assist you in writing your software.
If all you need to do is raise the volume, the easiest, fastest and least expensive way to do that is to use a set of amplified speakers with the MP3 Trigger. The second easiest way would be to create an INI file that assigns one of your triggers to volume up and down. Then you can press buttons to change the volume. See the sample initialization file in the guide for information on how to do this.
I think the OP is asking about the Qwiic MP3 Trigger, which, unless the Qwiic MP3 Trigger also uses an INI file and has an FTDI connector, is not what you’re referring to.
Good point robertsoncis!
kenan01, I was referring you to the wrong guide thinking you had a different product. Can you either give me your order or invoice number so I can see exactly what products you’re working with OR, can you give me the SparkFun part numbers of what parts you have? With that information, I think we can get this figured out for you.
I am working with a DEV-15165 SparkFun Qwiic MP3 Trigger and a
DEV-13975 SparkFun RedBoard - Programmed with Arduino.
I know how to trigger a sound file on the sd card, but the vol is too low.
I cannot use an amplified speaker because there is not enough room in my project.
From reading the guide the volume can be increased on the QWIC MP3 Trigger by connecting an arduino device ( DEV-13975 SparkFun RedBoard - Programmed with Arduino.) but it does not explain HOW to connect the two boards.
I have downloaded the Arduino software to my computer to Program the volume change, but I don’t know how the two boards communicate, physically.
There is a photo in the hook up guide of a Qwiic MP3 Trigger and a SparkFun RedBoard Qwiic connected with a jumper wire, but that does not help me with my hook up problem.
This would be so much easier to talk thru on the phone. You can call me at 713-703-6377 if it would help me explain my problem better.
If you had the Qwiic RedBoard, all you’d need is a Qwiic cable to connect the two through the Qwiic port but DEV-13975 doesn’t have a Qwiic connector.
OK, Here’s the connections you need to make to the non Qwiic RedBoard.
MP3 – RedBoard
GND – GND
3.3V – 3.3V
SDA – SDA
SCL – SCL
and optionally:
INT – D2
Example 5 in the library has the code needed for changing volume, that should get you the information you need.
Thank you, I will give that a try.
Ok got all of the boards hooked up and making sound. How do I input the code to get volume change. Do I hook the boards up to a computer ? Where in the computer do I write the code? I know how to write the code, but how do I access it on a computer.
Have you not used Arduino before?
It’s beyond the scope of what we can help with over the forums, but you might check out some introduction to Arduino tutorials for help in getting that setup and running.
