hi....
i need help on my project
i am using 2 arduino uno and want to connect it wirelessly and i am stuck on a point that i want to use a good transceiver as i want to send audio signal to the receiver arduino and to the receiver arduino i am connecting a sensor and want to receive signal form that receiving arduino i want to ask weather the nrf24l01 will work on this idea or should i go for something else...helpppp 
:~ :~ :~ :~ :~ :~ :~ :~ :~
What bandwidth for the audio data? Do you want reliable transmission? What's the maximum latency you can tolerate?
hi...
for the audio i am using a vrbot for controlling the robot..i want to control my robot wirelessly with my voice using vrbot but i am stuck on codes and also a confusion is there weather i can receive my sensor output from the second arduino...
so i was thinking to use a 2.4ghz trznasceiver nrf24l01 for it...
You don't need to send the audio (voice). Your vrbot can process the voice and send the associated digital command wirelessly.
XBee can send sensor data independently (without an Arduino).
The nrf24l01 is amazingly cheap at 7$ for 2, its not to hard to use
data is sent and received in 32byte packages so its up to you to put your data and format it how you want
I haven't tried any kind of high speed transmission, maybe ill hook up 2 spares I have and test the bandwitdh
I've never used xbee before mainly because of price so idk anything about that
Your vrbot can process the voice and send the associated digital command wirelessly.
can i have the codes for this????
so should i use xbee as it is easily available in india...
and i really need help in programming for receiving the sensor data(ping) and for the vrbot with arduino uno...
really need help
can i have the codes for this????
Here, I googled it for you:
thank u for the search but my project is complicated actually its based on this....
with some addition of using sensor to transmit the data to the base...
the problem with me is that i am new to this and also to its programming....
Well, it's all documented there for you, step-by-step. Just follow the instructions. Software is there too, you don't need to do any programming.
ya its true everything is documented there but i want to work on it with some advancement on it from the base... 
i got problem with the arduino uno.
i have uploaded the first hello world program but now when i am trying to upload a second rf program its showingg error but also in serial monitor its running hello world.
plz help me out of this
i am trying to upload a second rf program its showingg error but also in serial monitor its running hello world.
This implies you have the serial monitor open at the same time as you are trying to use the same serial interface to reprogram the board.
I've never tried this, but I imagine it would be unsuccessful.
checked everything but its showing following error
sketch_mar05a.cpp:2:22: error: nRF24L01.h: No such file or directory
sketch_mar05a.cpp:3:18: error: RF24.h: No such file or directory
sketch_mar05a.cpp:4:20: error: printf.h: No such file or directory
sketch_mar05a:11: error: 'RF24' does not name a type
program which i uploaded is
#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
#include "printf.h"
//
// Hardware configuration
//
// Set up nRF24L01 radio on SPI bus plus pins 9 & 10
RF24 radio(9,10);
still stuck =( =( =( =( =( =( =( =( =( =(
That's not an upload error
sketch_mar05a.cpp:2:22: error: nRF24L01.h: No such file or directory sketch_mar05a.cpp:3:18: error: RF24.h: No such file or directory sketch_mar05a.cpp:4:20: error: printf.h: No such file or directory sketch_mar05a:11: error: 'RF24' does not name a type
And do you have all those files?
i got it.... 
thank you
does anybody know about easyvr...
actually...i want some help in it..
i want to control my robot by easyvrbot...
but i want to do it wirelessly....
i mean to say i want to connect easyvr wid my arduino at transmitter part and wantt to move robot i.e receiver
i am using rf24. for wireless
can anyone help me with easyvr connection with arduino..i am not using easyvr shield...
Srry ive never heard of that, nrf24l01 is no problem if you need help eith that
can anyone help me with easyvr connection with arduino..i am not using easyvr shield...
Why not? Do you think the makers of the shield are just out to rip you off? There is a reason that someone took the time and trouble to make a shield.
