Wireless transmitter and receiver

[Rip]

I came across these items. Cheap and useful.

Transmitter
Receiver

Here's a link to a walkthrough.

I like the RF Link Transmitter - 315MHz, it has a good features. So i decided to buy next month.

thanks for the link. i might need to buy some of those.... im wondering if i can hook that into the pins on the iobridge, so that some of the electronics can be set up elsewhere... mainly my lcd display

I just got this RF kit http://www.seeedstudio.com/depot/433mhz-rf-link-kit-p-127.html from seedstudio. I have been trying to hook it up with the serial board but I have not succeeded. I am starting to believe that it will not work straight to the serial board...I might need to get another arduino board to set up as RX or TX to hook up directly to the serial board.

If anyone else has tried something like this please let me know!

what if you tried putting it on the digital out pin?

Do you have the wireless module ground connected to the IO-204 ground?  I still forget to do that every once in a while.

Quite often with these low-cost receiver modules you need to first transmit to them a balanced series of 0's and 1's to warm up the data slicer.  You could try sending about five sequences of $55 before the actual data.  My experience with several brands of these modules is that this is needed.  If you google you will find more info on this.  Also you may need to play with the baud rate to get the optimum range.

would one of these rf module pairs work if i was to connect them to a digital out? i was planning one buying a pair to hook up to the lcd screen modules so that i could have a remote display.

@electroman Thanks I will try our your suggestion...I figured that in this case the transmitter will be  on the iobridge serial board and the receiver in the arduino, since i can program better "decoding" on the arduino side.

I do receive a lot of noise. But I was able to receive some partial bits just recently. I will keep experimenting.

Thanks!
