i've recently bought myself an arduino board and have interfaced it with a lcd block to success only took about 20 minutes - not bad considering its the first thing i did with the board.
i've ordered a bluesmirf bluetooth module and am awaiting its arrival.
ideally i want to interface the bluetooth module and send a string via bluetooth to the arduino board to display on the lcd screen.. do you think i'll face any major problems doing this?
the only problem i can see at present is that the lcd screen takes ALOT of the digital outputs all except 0,1 and 13.
i plan to interface a cell phone with the board using the mobile processing api's (failing that i can resort to j2me as i know java).
just wanting to know if you can see any problems in my plan?
I think you can use the 0 and 1 pins if you power the arduino from a external power supply. the external power supply will not provide power to the usb chip on the board. The only issue could be that the bluetooth module has the wrong serial speed. but I read on the forum somewhere that this can be solved in the settings of that device
i will be using an external power source (a battery rig i hooked up today) for the final device so that shouldnt be a problem..hopefully.. i guess i'll have to wait till the bluetooth device arrives.
and then come back and beg for help.
are you talking about changing the bluetooth baud speed?
thanks, i don't know how you guessed i'm on os x i'll take it as developer intuition
do you have any ideas when the bluetooth arduino board will be out? i still plan on using the standard unit for this project but it would be good to know for the future.
as you seem to be the all knowing on arduino will i have any problems passing strings to and from the bluesmirf module using ports 0,1 on the arduino board?
well the bluesmirf module arrived and i managed to get it all working and can send a string from my mac using processing 0123 to the board and then have it displayed on the lcd screen.
the only problems i have at the moment is that the display update is a bit slow but thats because of the baud rate set on the module i'm waiting for sparkfun to get back to me with the datasheet so i can change the baud speed.
also changing the default password on the unit needs to be addressed os x allows you to use text passkeys to pair with bluetooth devices but alas phones (or at least my doesn't) don't so i also need info from the datasheet for the module to allow me to change the default password from 'default' to something numeric.
as all of the hardware stuff has been dealt with and the entire setup seems to function correctly i need to have a PCB created does anyone know of any good tutorials or introductions to PCB design? i have Osmond but i have no idea how to use it.
