I have a client, who ha a client, that would like a 3 button remote control. Depending on which button entered, 1 of 3 incandecent light* will come on. ( * that letter key not working on my 'board ). I've never done RC unit and he need it by 6/13/12 . The original de*igner can't be found and client referred to me la*t week.

Doe* anybody know of a *imple enough circuit that I could get working ? Range need to be 10' - 20' .

AVR410 and AVR415 are IR TX and RX application notes with ready made code. Simply use 3 buttons.

Does the receiver already exist, or is that part of the project?

If you need both receiver and transmitter, the Micrel QwikRadio chips are excellent for simple tasks like that:

Google X10 and take a drive to Radio Shack.

While your there, buy a new keyboard ;)

John, the only problem with that is I don't know which local electronics store would have an RC5 transmitter, since it doesn't say on the packaging. I'll check around on Monday, though.

Jim, it's part of the project, BUT my client doesn't care if I just use things from off the shelf. Those chip are nice, man ! Another good suggestion, but I don't know if I'd have time enough ( I smell RF issues on the PCB, maybe, at some of those high frequencies when I layout/build its PCB ( might be wrong, they aren't super high )) !

I'm so used to avoiding R.S. because of prices and they've just about quit selling components, I forgot about them ! They've GOT to be the best time-option I've got !

That's just a simple infrared LED.

Larry,

ALT+083 => S
ALT+115 => s

(this works for me on Windows but not Linux - the digits are typed on the numeric keypad while [Alt] is held down)

Jerome, from memory there are short range IR switches available at dealextreme like this one that might be the basis for your design. It appears to have both transmit and receive IR diodes mounted. Hopefully there is some data somewhere.

Or this one does 4 channels via one control via wireless.

I called THREE Radio shacks and NONE have R.C. for what I need, just IR detector modules. They ain't what they used to be !!

Ross, the 4 channel gizmo is PERFECT, made-to-order... but the 3-7 day delivery just jams me up !! :cry:

Too much drinky-drink...not a bad way to go ! No problem Cliff, you have too much knowledge in you and it's oozin' out of your eyes and clouding your vision ! :wink: Man, HOW do you find stuff like alt + 115, etc ( confess, you have a full blown book ALL about Windoze that you keep under your mattress, huh ( jokingly asked )? ) ?!

I didn't think high and mighty Digikey would have anything like what I needed, but I'm glad I called and asked... here's what they gave me:

Receiver:
http://www.digikey.com/scripts/d...

Matching Transmitter:
http://www.digikey.com/scripts/d...

I found this, but we can't contact them by phone and find out how long shipping is, EMAIL ONLY... :!: :roll: :?

http://electronics-diy.com/store...
Near middle of page, $24.95.

When this is all over...I'll have to bust out some RC5 code/circuitry ( Just in case there's a next time ).

Peter Gunn's on, then original Mission Impossible...gotta go .

HOW do you find stuff like alt + 115, etc

Back in the days of MS-DOS before Windows was even a twinkle in Uncle Bill's eye it was common practice to use ALT+NNN to get to characters that could not easily be typed on the keyboard.

As I prepared a lot of the MS-DOS translations (Italian, Spanish, French, German, etc) for our PC range I found myself doing this a lot. Of course things were further complicated by setting up code page 850 or whatever to replace code page 437 back then - thank God for Unicode and UTF these days!

I still use alt + 248 to get the degree symbol °
alt + 171 and 172 give you ½ ¼ which can be handy.

Launch a Windows built-in Character Map application and get any characters you ever need.

So, how do you type programs without an s button? I think my marbles would have been lost a long time ago.

Oh, forgot, they have been lost for some time.

I wonder how long it will take for you to "produce" a ready to work NOW alternative. Truly, I sometimes think that the "and I want it now" type of customers are not worth the aggravation.

At least you now know of some other supply chains.

Cheers,

I'd have a look at http://www.smarthome.com. The have plenty of remote controls for all kinds of applications.

They are based in the US and should be able to ship/deliver in days. DX is cheap, but you'll pay it with a couple of weeks of delivery times.

hey indianajones:

what about HT12XX devices from Holtek?
I've used them in the past with success.

Torby, it started the same day I started this thread, or maybe the day before, and I was barely using the PC since I was busy with other things. The key must have been stuck, because a few days after my last reply here, ... it started working again. :roll:

Ross, he was in a rush to meet his client's contract deadline since the original engineer just disappeared and couldn't be found. I don't know what happened there. I'd agree with you about the "want it NOW" clients...

Markus, I couldn't find units on that site that client would like ( too big and I didn't find anything for general control, but I didn't search every remote's page either. :wink: )

Nachus, I've heard of those. So how easy or hard was it to design a transceiver combo. using them ?

Markus, the eval. kit below is from the same company I referenced in an earlier post. THAT kit uses relays and is a pain to interface to a MCU just to detect a button press. Powering the module required a Vin_min = 7V, so a 2nd regulator chip just for that and a Iload_min = 600mA to energize the coil. I would've had to use power resistors JUST to get a simple R_pullup function to MCU inputs ( THEN would've had to get the "pull_voltage" in a range that the uC could handle :roll: ) ! Like I said, a Digikey rep suggested that kit to me and he knew about it since he was using it to control household stuff.

In the time it took to come to a right decision...I could've just ordered from one of the links given from this thread ! Customers, customers...

http://www.digikey.com/product-d...

EASY I/F'ing, the antenna screws in easily and next day from Digikey. :D One more to add to a good list from this thread, thanks again 'freaks !

Looking at your solution, I misread your initial post. I had the impression you were looking for some finished, packages remote control device for 110V AC lights.

Thanks for the link, interesting modules.

I forgot to say that the eval. kit from my previous post will also work with the transmitter I mentioned before.

For the RC units that you guys brought up and have used, how reliable are they ( work on EVERY press ) and do they last a long time ?

The app. does control 2 types of AC lights, but 1 set of about 12-14 needed to flash at a low frequency and the other set ( 3 recessed lights, lighted 1-2-3-1-2-3 with only 1 on at a time ( it's all part of a showroom display ), with a short duration for both . My client designed a 20' tower booth and 1 side of it has a GIANT mockup wall light switch his company put together ( 2 wires in the booth go to my MCU's R_pullup and gnd. The action starts when a customer closes the switch, the blinking and 1-2-3 starts. Then when a showroom employee hits the RC button, 1 of the 3 lights stays on and somebody wins a prize .

Transceiver --> MCU --> SSRs.
