Help with LED cluster project.

[Fida]

I am currently working on a LED LIGHT SYSTEM. I would like some design engineer to help me with making the circuit for this LED light system.

I will explain to you what i am trying to make. A LED LIGHT SYSTEM which has to modes, 1st mode flashing and, 2nd mode continues on. Now with these modes in place i would like a remote control to activate them using RF or some sort of wireless technology. (range of about 30-100 foot if possible).

I am currently using white LED cluster (19 LED's drawing about 270mA from a 3.7vdc mobile phone battery)

The reason why i am using a mobile battery is size and power output.

If you require any more details please contact me.

Look forward to the replies thank you.

Fida,

well, it may sound like a "small" project to you, but
if you want to use RF or at least IR remote control
it is a big project to develop from scratch.

Have you looked at your local electronics store if
there is something available ?

If you go the RF way, better use a ready made module
like this one

and use µC to control everything.

Sidenote: I like analog circuitry, but since the µC-way
is mostly (nowadays) easier, just go for that.
Learn how to program PIC or BETTER ATMEL µC, since
the ATMEL µC's can be programmed via GCC.

Cheers,
Hannes

Get a IR encoder/decoder pair.
TINY-IR-II infrared decoder/encoder ICs

270 ohms sounds low??

Hello everyone! please help me!
I want to make a project using PIC16F84A .In that project, I want to use two 7 segments (common cathode ) but I don't know how I am multiplexing them...Any one who knows that helps me...Thank you all...

Demon-13,

hijacking threads ? not a very nice way.

nevertheless i'll give you a hint:
use one port for the 7segs, and one pin of another
port for muxing them.

thank you man..i got the solution........I use port B to display two 7-segs and use port A for multiplexing
