Welcome to the CyBENCH Project Pages - 4bit RF remote


Part 1 - Theory of operation

In the beginning........

There are a number of remote control projects available on the internet.
Most of which require a good knowledge of electronics and possible the
ability and equipment to program a microcontroller of one variant or another.

My original idea was to use a handful of maplin parts to create a remote control system.

I then began to look at cost, the RF modules in particular.

In the background, I recently purchased a cheap car alarm, (details in part 7)
I intended to steal it's RF section for a few round-the house applications.

This has all the RF gubbins needed including two keyfobs and batteries.

Data:
The chipset used has four inputs and outputs for the user to play with
Addressing:
The device address is selected by changing solder blobs
Each of the 8 address lines can be high, low or not connected.
Data for the chipset is also in section 7
