So if I understand you, I need only to change the wires and rewrite something in the code. Right? So I can order them. Right?
Yes or no?

Well, I read a bit.
So maybe all of this will be work together. Only needs to manipulate things on the devices. Am I right? Somebody agree or disagree it please.

What do you mean "wiring change on one of the boards"?

Okay, but it can be done with some kind of program what i upload to lilypad, right?

Good to know.
What do you advice? Is there an accelometer or a compass what doesn't use SPI and can be used with these devices?

Well, I use the mini sd module without rx and tx pins. I need that only for play a few files.

Well, I haven't found each one's current, I found some datas about that, maybe that is under 200mA.

So everything is compatible? Is the compass use rx and tx? If yes, is it a problem that the bluetooth module and the compass (maybe) use rx and tx?

SD card doesn't use rx and tx.

I have already wrote that:
Lilypad power supply https://www.sparkfun.com/products/11259 (instead of Coin Cell Battery)

Which one won't be work for this? And I didn't understand your last question.

Will have I enough V, enough free pins, etc.?

[Will be the new and the old devices work with each other? They would be work at the same time by an Arduino Lilypad.]

Will be the new and the old devices work with each other? They would be work at the same time by an Arduino Lilypad.

These are the current devices:

-Flex Sensor 4.5" https://www.sparkfun.com/products/8606 4pcs -Flex Sensor 2.2" https://www.sparkfun.com/products/10264 1pcs

-10k resistor 5pcs

-Lilypad Arduino 328 Main Board https://www.sparkfun.com/products/9266 1pcs (well, we ordered that from another place, I have AU 1045 instead of AU 1115)<-maybe this is not important

-LilyPad Coin Cell Battery Holder https://www.sparkfun.com/products/10730 1pcs

If they’re in one circuit, I have one free analog pin and (maybe) 14 free digital pins. They have worked for me. These would be the new devices:

-Lilypad power supply https://www.sparkfun.com/products/11259 (instead of Coin Cell Battery)

-LSM303 Breakout Board - Tilt Compensated Compass https://www.sparkfun.com/products/10703 (with my teacher’s program it would work only on digital pins – hope that can be used for my project)

-2.2" 18-bit color TFT LCD display with microSD card breakout - HX8340BN http://adafruit.com/products/797

-JY-MCU V1.04 Bluetooth module http://www.ebay.com/itm/Arduino-Wireless-Bluetooth-Transceiver-Module-Slave-4Pin-SerialDuPontCable/160879748403?pt=LH_DefaultDomain_0&hash=item25752e2533

-WTV020-SD-16P Mini SD Module http://www.ebay.com/itm/MP3-Voice-module-U-disk-audio-player-SD-card-voice-module-WTV020-SD-16P-/160806790230?pt=LH_DefaultDomain_0&hash=item2570d4e456 (And it has a small speaker from a car)

I have the mini SD module, but I haven’t tried out with the other devices.

My question is: Will the mentioned devices compatible with each other? They would be in ONE circuit. The Lilypad Power Supply and the Lilypad Arduino would control them and power up them. Can I have the courage to order the new devices too?

I need to order the things as soon as there's a sure answer about the compatibility. So somebody please help me. Thanks.

Tried to connect the cp2102's 5V to the bluetooth VCC, cp2102's GND to bluetooth GND, and lilypad's rx to bluetooth tx, lilypad's tx to bluetooth rx. Nothing.
I don't understand, the power is from the PC, not from the CR2032 battery. Still no blinking red leds on the bluetooth module.

Tried to connect the bluetooth module with Arduino Uno, with the same program uploaded on there and the bluetooth's red leds are blinking.

What the hell is wrong with it?

Hy all!

I have a Lilypad, there're some flex sensors connecting to them, and there's a CR2032 what gives power to the flex sensors. If i connect the bluetooth module, neither the lilypad's led won't blink if I press the reset button, nor the bluetooth module's led won't blink.
I think the bluetooth module can't get enough power.

How should I give more power without killing something? I will add more things to the Lilypad in the near future.

Hy all!

Where can I order this thing?
I have found mini SD card modules, and it said: 8、Two module types of WTV020-SD-20S and WTV020-SD-16P
What is the difference between them? Will this library work for both?
