Hi there guys
I'm doing a project where I have a lilypad xbee and an arduino duemilenova and i would like to connect them through xbees.I tried successfully to program the xbees through xctu to connect with each other.Thing is until now i was using a normal lilypad not a lilypad xbee and i have no idea how to program the lilypad xbee,is it possible to get a 6 male header and solder it to program it like any other lilypad or are the pins used for some other reason?

ED:hi again,it seems i had a misunderstanding,lilypad xbee is must be connected to the lilypad mainboard xD

Hello
I'm having troubles with my project,at first i wanted just to use arduino lilypad,but then i couldn't figure out how to work the wireless RF transmitter and receiver with my LCD so xbee came in mind.
Now what i want to ask is,if i get xbee on lilypad and xbee on duemilanove will they be able to connect to each other(keep in mind i do not have much experience with xbee).So i'm thinking of making duemilanove handle my lcd while lilypad works on the other objectives i have.
If you need any more information i will gladly give it.

Hello there
I've never used RF transmitter and receiver before but i need to in order to complete a project i have
Here are the components i use:
LCD: http://uk.farnell.com/fordata/fdcc0802c-flyybh-91le/disp-8x2-stn-lcd-3v-grn-b-l/dp/1847924
RF receiver: https://www.sparkfun.com/products/10532
RF transmitter : https://www.sparkfun.com/products/10534
So what i want help with is that I do not know how to connect them physically,is there a tutorial i can find somewhere or if someone can help me with this some other way?(The micro controller used is Arduino Lilypad if that's of any help)

Thank you for your time
4  Using Arduino / Installation & Troubleshooting / Lilypad sync problem on: November 26, 2012, 07:37:23 am
Hello there
I'm doing my project for my final year and i have a problem uploading the code.I get this error: avrdude: stk500_getsync(): not in sync: resp=0x00
I'm using windows 8 and did the "Disable Driver Signature Enforcement" thing,unistalled the driver and then installed it automatically when I plug in the USB to Serial TTL Cable
I'm sure the chip i use is the 328 and not the 168 and I also checked if i had the com wrong,which i didn't.
Could someone help me resolve the problem?

Thanks for your time

P.S. I pressed shift while uploading and it gives me this avrdude: usbdev_open(): did not find any USB device "usb ,still having tha same problem i guess

Sorry for poorly explaining my thoughts anyway,

The lilypad will be somewhere near the chest area of the t-shirt so,the display will be wireless,the oxymeter(the oxygen sensor) wired to the display or wireless on lilypad(i really don't know which sensors for blood oxygen are out there,i'm currently searching for it),heart rate sensor wired to lilypad(which i want it to send the reading to the display),temperature sensor wired and vibe sensor wired on lilypad.

So the distance of the data to be transmitted is from the hand to the chest so basically the distance of my hand which i'm pretty sure is not over 50 to 75 cm

I know that a project needs to be carefully managed at every angle to get top grades but that's why i want to have more quality into it (btw thanks for reading and helping out even a bit)

A graphic display would be best i think,just showing numbers won't be good enough for getting top grades.
I'm in the uk so the provider is actually quite near me smiley-razz ,sorry i guess i should have fixed my profile a bit better so my location shows,anyway about the blood oxygen sensor could someone tell me if i'll be able to connect both the display and the sensor in one wireless technology for the lilypad(i heard a friend of mine that bluetooth needs one micro-controller  per input)so i don't want to buy the sensor and then never use it.

Hello there
I'm on my last year in Beng as an electrical and electronic engineering student and as this year's dissertation i chose to do a Lilypad based heart rate monitor on a t shirt,I bought a starter kit from coolcomponents and the lilypad is working just fine i tested it today,i've also ordered a heart rate sensor: http://pulsesensor.myshopify.com/collections/frontpage/products/pulse-sensor-amped <--- this one to be exact ,so what i am more interested in doing is making my own wrist display and connecting it through wireless technology like bluetooth i guess, with the lilypad.In the starter kit it is included a temperature sensor and a vibe board,so i'm thinking of adding those 2 as well,like temp sensor gives the temp of the weather somewhere on the display and the vibe board to vibe when heart rate rises a lot for example when running so you can look at the display to see your heart rate.There is one small thing i would like to add as well but i really don't know if it's possible or not,i would like to get my hands on a blood oxygen sensor and give oxygen levels in the display as well.The thing is i really don't know much about building my own display or which and how wireless technologies work in microcontrollers(the course doesn't cover this till after christmas but i need a head start to finish my project early),could you give me some advice on where to look for the display or learn more about wireless in microcontrollers

Thank you for your reply dxw00d
So just to be sure,both can be connected to the lilipad right?(I'm not too confortable yet working with microcontrollers as it was an optional subject for this year and it's still early to be too sure about these things)

Hello everyone
I'm a electrical engineer student and for my final year project i wanna do an arduino lilipad project,i'm thinking of making a t-shirt that can show heart pulses,blood pressure,oxygen levels in blood,i'm not sure which of them are possible,but i guess that's what i kinda ask here smiley-razz i would also like to hear your ideas if you'd be so kind as to help out a bit with the ideas,i would like to make it to keep a log of all the calculations it does

Thank you very much for your time
