virtual wire

By comparing temperatur, Arduino tells you with RF Link if your room is too cold or too warm.

I would like to share my code. With this code your Arduino tells you by RF Link  if your room is too cold or too warm. You need 2 Arduino's.

It is just a part of a bigger project. But you can modify the code and make some great stuff. If their are some questions feel free to ask. RF link is amazing.

 

Question about sending integers using virtualwire.

// Tested with IDE 20 and VirtualWire 1.4, only working with those.
// RF Link using VirtualWire to Transmit messages
// simplex (one-way) receiver with a 315MHz RF Link Transmitter module
// tx pin 3 on Duemilanova (arduino)
//vw_setup(300)&n

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.

virtual wire and sound

hello .... i am trying to have a machine (equipe with an arduino (virtual wire library ... TX ) ) sending information over another arduino equiped with virtual wire library(RX) and pduino firmata ( the cicuit is  (resistor 10k from pwm ... to the ground) 330 ohm from pwm to the analogPin() so that i can read analog input into the pd patch ... right?????)

i think the key is how to convert the rx signal into (map, 0, 255,) ... or something like that but the question is how ???...
