Arduino Basics

WARNING: Please check whether you can legally use RF transmitters and receivers at your location before attempting this project (or buying the components). This project is aimed at those who are looking to automate their home. 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 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 - ** you are here ** 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 4 : 433 Mhz RF remote replacement tutorial Carrying on from my previous "433MHz transmitter and receiver" tutorials ( 1 , 2 & 3 ): I have thrown away the need to process the signal with a computer. This m...

Project 3: RF Remote Control Emulation In the first tutorial , I introduced the 433 MHz Transmitter and Receiver with a simple sketch to test their functionality. In the second tutorial , the 433MHz receiver was used to receive a signal from an RF remote. The RF remote signal was coded based on the pattern and length of its HIGH and LOW signals. The signals received by the remote can be described by the code below:   Code comparison table ...
