@Ultramagnus
I didnt get u...
@CaptainObvious
Yup i have seen that tutorial befre. That got me thinking about VirtualWire. bit of googling made me find out abt SoftwareSerial. Still undecided. Thanx anyways.
@ Leon Heller
I guess I will folloe ur technique. Randmly pick one and see how it goes.

Thanx for all the replies guys. smiley
It would be gr if someone can tell me the difference between the two. Else its kinda ok. I will get to know it in a couple of days time after trying it out.  smiley-wink

its ASK modulated. My problem is what sort off progrmmin like SoftwareSerial.h or Virtualwire.h to use to send out the data through Arduino.

So no clear winner regarding which to use? ease of programming wise?

I only have the tws-434/rws434 Modules.

Hi,
I have two Arduino Boards with me. I need to do some kind of wireless communication between them. I have a TWS-434/RWS-434 RF module. I need to transmit a  matrix (containing values 0 , 1 , 2). I have heard abt SoftwareSerial.h and Virtualwire.h libraries(but has never really worked with either of them  :-[ ). I need to correctly transmit this matrix only once. So speed isnt a criteria. Can someone please guide me in which path I must choose to go about? ie) SoftwareSerial.h or Virtualwire.h. which will be better? Or is there a better option? Btw wat is the difference between the two?  :-/  I would like to keep program size as low as possible.

Hoping for a fast reply.
Thanx in advance.  smiley

Pressing reset button only stops the execution of the program for a couple of seconds. and stop button doesn't stop the execution of the program written in your Arduino board. Whatever you have written inside the loop continues its execution till u switch off the power to the Arduino board.  smiley

and Welcome to the world of Arduino.

Thanks lefty  smiley
It worked played around with time constant and made it work. But actually how should i design the time const? currently i am using 47k and 1uF cap. It is working though.
I gave it as Vcc(5V) -> resistor -> cap -> gnd. and voltage across cap was given to reset pin.

Is it possible for doing a Auto reset of JK FF. like putting JK FF to output 0 wen I switch on the power supply and maintaining it till next clock pulse comes(ie) without me manually clearing it ). I am using a 7473 JK FF IC. It has a CLR pin. which is active low.
Hoping for fast reply... smiley
