Arduino Basics

There are 4 parts to this tutorial: Part 1: Testing the 433 MHz RF transmitter and receiver Part 2: Receive and interpret code from an RF remote - ** you are here ** Part 3: Transmit a known 433 Mhz RF code to a 433 Mhz RF device Part 4: Record and play back a 433 Mhz RF remote signal To get the most out of this tutorial - it is best to start at tutorial Part 1 , and then progress to Part 2 then Part 3 and then do Part 4 last. Doing the RF tutorials in this order will help you to understand the process better. Project 2: RF Remote Copy In the previous project , we transmitted a signal wirelessly from one Arduino to another. It was there to help troubleshoot communication between the modules. It was important to start with a very short distance (1-2 cm) and then move the RF modules further apart to test the range. The range can be extended by soldering an antenna to the module, or by experimenting with different voltage supplies to the modules (making sure to keep wi...

Doing the RF tutorials in this order will help you to understand the process better. If you are looking for a way to communicate between Arduinos, but don't have much cash at your disposal, then look no further. These RF modules are not only affordable, but easy to use. They are much easier to set up than an XBee, plus you can use them without the need of a special shield. Before you rush out and buy a ton of these modules, make sure that you are not breaking any radio transmission laws in your country. Do your research, and buy them only if you are allowed...
