A new MP3 Sound Module....


My first Post on tis forum....
I've been experimenting with DFRobot's DFPlayer Mini MP3 player as a small sized sound module

for an upcoming build. (see URL below)
The Player is an approx. one inch square with a built in 3watt amplifier and Micro SD card. You

can control it using normal push buttons but I have chosen to send it instructions via an

Arduino Pro Mini.

I've programmed the Arduino to read the RC joystick movements of an unused channel and have the

mp3 player toggling between engine start, engine run, horn and engine shutdown and restart.

Using the same method you could link MP3 tracks according to different engine speeds, but I'm

not sure that level of sophistication is required.

So far, I'm very pleased with its performance and it seems to be a very cost effective and

compact solution.
The parts that I am using are:
1. DFPlayer cost about $12CDN
2. Arduino Pro Mini 5volt - $13CDN
3. Pololu RC Switch - $6CDN - Used to turn on the device
4. DC voltage Regulator - $5CDN - Used to knock down the voltage to 5V.

I purchased the parts from Robot Shop.

Please let me know if there is any interest as I can post my source code including the

connections diagram.

cheers, Brian

I have a couple of Arduino Pro Micro ATmega32U4 and some DFplayer mini to do some tests, have you already written a sketch to try?
