When you press the buttons on your 433-MHz remote control transmitter, the received 433-MHz RF codes should then be printed in a “Decimal number/Bit/Protocol” format. The first result — from button “A ...

And, using a few off-the-shelf parts [hesam.moshiri] shows us how to take advantage of this piece of spectrum by designing and building a programmable and versatile 4-channel 433 MHz remote control.

[Reza’s] methodical investigation of this remote controlled outlet let him patch in with an Arduino using a 433 MHz transmitter. This is a single-device unit, but the techniques used here sho… ...
