Using 433MHz RF Transmitter Receiver Link Kit with Arduino Uno and Mega 2560

Projects Networking, Protocols, and Devices

Hello,

I recently picked up 2 of these transmitter/receiver pairs from dx.com: 433MHz RF Transmitter Wireless Module for Arduino - Blue + Yellow - Free shipping - DealExtreme

I've been following the tutorial on Instructables.com here: http://www.instructables.com/id/RF-315433-MHz-Transmitter-receiver-Module-and-Ardu/?ALLSTEPS

For the life of me, I cannot get the receiver to take in any message that is sent to it. I've also tried a bunch of different circuit configurations including the one on the actual dx.com product page, but to no avail.

Before I waste anymore time trying to do this, is it even possible? In almost every tutorial I've seen on this, somebody is almost always using an Arduino Uno and never a Mega, let alone the two in sync. I can't seem to find any combination of example code, schematics, and transmitter/receivers to get it to work.

Does anybody have any experience with this and could help me out?

Thanks a lot.

Most Instructables are nonsense, if not just seriously misleading, and are really to be avoided. I suggest to start with the VirtualWire library and the simple examples that come with it. It works very well and there are lots and lots of examples.

It should not matter that you are using a Mega, but if you run into troubles, describe them and post a clear wiring diagram.

Thanks for your reply. I just got it working. I'm now using this schematic: http://electronics-diy.com/schematics/1289/arduino-rf-link-using-433mhz-transmitter-receiver-modules.jpg

I ignored the part that attaches to pin 1.

I hooked up the receiver to A0, same with the transmitter. All I do is analogRead and analogWrite respectively for the receiver and transmitter and that was it :slight_smile:
