arduino: a cheap board for E11 blaster effects

[ravage79]

Hi I'm new to the forums here and am thrilled with this design I have been looking forwar to building my own e11 for a few years now. That said I have a few questions, how does the file name system work ie 001.mp3 = reload sound, do you use multiple folders and lastly for the open source is there a web page where I can contribute any changes that I make to the design?

 

TY.

[skyone]

the name system work as requested by the data sheet of the mp3 sound module. In this case the files and folders must be named 001, 002, 003... you can use one or multiple folders (i used multiple folders). You are welcome to share any contribution about the code and circutit here.

Skyone have you tested the WT5001 sound module, need some feed back before I buy!

Thanks. Michael

[skyone]

it was delivered to me last week but i didn't have time to test, cause the weekend comic con. in Milan

i will test during this week with arduino nano

[Chivo]

Thanks

Looking forward to your feedback.....

Ditto!

the module works fine

while plays mp3 files without problem and with a very good quality; wav files are supported (44.100hz/16bit/stereo) but with issues: the file starts to play only after 1 or 2 seconds of blank sound with a fading-in effect. tried to lower the sampling rate without any change.

something odd: if you want to keep the files order, firse must create the mp3 playlist on hard disk (0001.mp3, 0002.mp3, ecc) and when ready copy to the root of the micro-SD card. If you rename or change something on microsd card it will messy the order.

I used 2 watt stereo speakers @ 8ohm: if used in mono no problem, when stereo you can hear clipping. With a mini amplifier no problem at all also in stereo mode.

The serial code is almost the same of the bigger mp3 sound module (the one i used on my blaster), this one is more basic because doesn't support folders.

So if you are going to use this sound module you will need to modify the serial commands in the code i released for this project (very easy)





the video test:

the code used in the video

const int buttonPinFire = 7; // FIRE

// variables will change:
int buttonState = 0; // variable for reading the pushbutton status

void setup() {

// initialize the button pin as a input:
pinMode(buttonPinFire, INPUT);

// initialize serial communication:
Serial.begin(9600);



Serial.write(0x7E);
Serial.write(0x03);
Serial.write(0xA7);
Serial.write(0x1F); // volume max
Serial.write(0x7E);

// start sound
Serial.write(0x7E);
Serial.write(0x04);
Serial.write(0xA0); // A0 for SD card
Serial.write((byte)0x00);
Serial.write(0x02); // track number
Serial.write(0x7E);
delay(3000);

}

void loop()
{


buttonState = digitalRead(buttonPinFire);
if (buttonState == HIGH) {

Serial.write(0x7E);
Serial.write(0x04);
Serial.write(0xA0); // A0 for SD card
Serial.write((byte)0x00);
Serial.write(0x01); // track number
Serial.write(0x7E);
delay(300);
}

}

Thanks for that Skyone.

 

Will give this one a try as my somo14d module is not very good, don't like the clicks and if I add the 3watt mini amp it's worse.

 

[skyone]

i also received a new set of speakers and they perform well

 

size is 70mm x 30mm, the seller is SourcingMap

 

i am waiting a second set i ordered from the same site, should perform even louder because @ 4 ohm (the mini amp will perform best at this ohm rate)

 

70mmx30mm Rectangle Shape Aluminum Internal Speaker Loudspeaker 4 Ohm 3W

any chance you'd be willing to upload your audio files?! I can host them for you or suggest that they get placed on a public drop box or google drive share?!?

i sent you a pm

[skyone]

i am building a new set to show at Arduino convention in Rome in October

today i soldered the modifications on LED constant current drivers regulators

they are ready to be soldered to the RGB Led and to link to Arduino digital outputs

 

 

 

[E-Vader]

Hope you sell this as a kit, One day. Great work!

[wolfpolice]

I follow the job for a long time, the evolutions and tests, really good work. I ordered all the stuff and I started to make my own.

[dlord98]

Fantastic project !!!!alot of work      Can you share the mp3 file

and greetings from arduinoE11 at CE2!

Hi skyone, I have a question, in the diagram, in each ground line of buttons there is a resistance of 10 kohm (r2,r3,r4), this is correct because I do not see in the list of components. greetings from mexico.

[skyone]

you are right, for each button you need a 10 kohm pull-down resistor, as showed in this basic tutorial:

i edited the list in the first page

thanks skyone I am in the process of buying everything, here in mexico they have no idea of the main components, so all buy from usa and hopefully in a month or two to have everything and start the project, if I have questions I hope you can help me . greetings.

Just curious, can you use the MP3 player module I linked below for this setup? Apologies if I am asking a ridiculous question, I know almost nothing about how all the components need to be compatible. I happened to come across the slim type version of an mP3 module and thought that might help reduce space issues.

i think yes

you can control it via TTL serial commands with arduino

but it needs 12volts

Thanks Manuel. I am not even close to starting a project like this but thought I need to do my homework once I do. I guess 12 volts means larger battery so that would cause spacing problems. 

[Skyminer]

Looks like it can run on 3.6v up to 12v

[Hunter205]

Not going to lie... This is awesome, looks like it way over my head but I want one! Great job!

[micflair]

Please take my money as soon as possible for one of these ready to go!
