Send data from Processing to Arduino

Hi everyone,

I am trying to send 70 values from Processing to Arduino (as fast as possible), in order for Arduino to feed with these values a servo driver shield. What I tried to do in my code is to send the data one by one and each time a value is received Arduino confirms that to Processing in order to move to the next one. However my code doesn't works properly. Please have a look below to see what mistakes do I have, or if you have a better solution for the procedure please share it! Thank you for you time!

Not receiving the correct data. Using VirtualWire

I would like to use a code for sending the temperatur and humidity. One day before, I started with sending just a short message like: LMR is cool. TX= Transmitter RX=Reciever

It only worked when I used:

Arduino IDE 020 and VirtualWire 1.10 for RX

and Arduino IDE 020 and VirtualWire 1.10 for TX.

 

When I use Arduino IDE 1.0.3 and VirtualWire 1.4 for RX 

and Arduino IDE 1.0.3 and VirtualWire (VW) 1.4 for TX it didn't. 

 

read raw gpa data from gps module to arduino

Hey guys I am trying to read raw data from a gps module using TTL communication on RX pin 0 on the arduino mega. i dont know how to program it since i am total noob at arduino programming. 

can someone help me out please.
