FOR CODE + SCHEMATICS, SEE LINKS BELOW!!!
This project uses an InfraRed (IR) Transmitter / Receiver pair to send information wirelessly. Both the TX and RX circuits use a PIC16F684 microprocessor and implements the SIRC (Sony InfraRed Communication) protocol - exactly the same as a TV remote control. In fact, you could control this receiver circuit with a Sony TV remote control - using the channel up, channel down, volume up, and volume down buttons! The data received is displayed on an LCD display, and each of the 4 different buttons on the transmitter will turn the servo to 4 different positions.

This project was based on Nigel Goodwin's PIC Tutorial 5_2. If you would like my circuit diagrams or PIC assembly code, you may download them at the following five links:

really good project! very dedicated. Congrats.

Yes, for any type of two-way communication, both "stations" need a transmitter and receiver - which can be combined as one circuit. My project was only one-way communication, so one station was a transmitter and the other station was a receiver.

Excelent project!

Aaron: great video and project! Problem is that Nut & Volts no longer has the project posted, so no access to ASM or HEX code! Thanks for sharing :-)

@SamuelAaronWard 11 лет назад

@Brian O'Brien ...I would probably use 2 different device IDs. Only the intended RX device circuit would respond to its own TX circuit.

nice project

@Da3watAlkheer 12 лет назад

GOOD JOB !

@SamuelAaronWard 11 лет назад

No, you must program both the transmitter and receiver circuits' PIC chip with the Assembly code. And you'll have to modify that code to get it to serve your purposes - unless you're just wanting to turn a servo to 4 different positions as I did in the video.

Hi First of all I would like to say GREAT JOB ! .. really like it I have some Question regarding IR sensors.. can you give me the name of transmitter and the receiver ? ...also according to diagram you did not use any amplifier ( can u tell what is the maximum distance that receiver can pick signal coming from transmitter). waiting for your response

@SamuelAaronWard 10 лет назад

The transmitter / receiver worked up to about 12 - 15 feet. This can be increased.

@MrBrianJohnOBrien 11 лет назад

nice... What would you do if you had to have two channels of data you needed to transmit. Are infrared pairs (tx/rx) on slightly different bandwidths.

@SamuelAaronWard 11 лет назад

@ EddieVanHalen1977: Turn down the volume on your computer. Your volume issue is not a defect of the video. Thanks! :)

@yuchoy1 12 лет назад

Is it just me that can't find the code? There are numerous references to nutsvolts in your excellent project PDF. Since the code is not available there, or in any of the links provided here on RU-vid, where might we find your code? Thanks for your help!

@atsul.7943 10 лет назад

Nice project. Am new to electronics and I want to dive into programming of chips. Please any advice?

@brodymoodley837 12 лет назад

hey. im a student studying electronics as one of subjects, im really interested in making this for my pschool project, however im not a genius (as yet) do you have any other simmilar circuits but a tad bit more basic? cheers.

@valdessong5241 10 лет назад

What is the maximum distance at which your transmitter work?

@Dogex670 12 лет назад

what range does it work? a few inches or a couple meters?

@destinyfate49 11 лет назад

Transmitter / Receiver If i hooked up these two modules with their voltage source. they automatic transmit and receive? without having to program a PIC micro-controller. a reply will be very much appreciated.

@HyoSanginkorea 9 лет назад

hi, I see your Project with effect. How to I get download? google docs is wrong connection.(may be permision).

@k.kwan718 9 лет назад

Hello Samuel is it ok for you to send me the code of this project because I am a PIC beginner and dont know the program for PIC

@EddieVanHalen1977 11 лет назад

good video but the volume is WAY TOO LOUD. Thanks for the info though.

@SamuelAaronWard 11 лет назад

If you would like my schematic or PIC Assembly code, I would be happy to send them to you. I do not really have time to help people with their projects. Please understand that I have received about 1,000 e-mails just like yours. If you have a specific question about the circuitry or code, I am willing to answer. Thanks -Aaron-

Hello Samuelaaronward I like your video on youtube, so can you show IR led transmitter circuit diagram thanks so much

@SamuelAaronWard 11 лет назад

@Brian O'Brien

@yuchoy1 12 лет назад

Check page 4 of your project PDF(IRTXRXProjectAaronWardDecember2011.pdf): "Software: In order to modify the PIC Assembly (.asm) code found on the N&V website, you will need a plain text editor such as Microsoft Notepad" No links for code :-( Everything is so well laid out, but now I'm stuck.

@13nishk 12 лет назад

Can you send me the code for this project?

@justbraden162 10 лет назад

Would you be able to send game console commands if so where did you get the processer and how much also would you need a specific program to code the procceser

@SamuelAaronWard 10 лет назад

Braden, yes, you would be able to send commands to a game console; however, you would have to know what kinds of signals the console expects to receive and duplicate that with your receiver circuit. You may use any microprocessor of your choosing, so long as it has as many digital output pins as your game controller has buttons. And yes, you will need to write program code for each the transmitter circuit's microprocessor and the receiver circuit's microprocessor. (No, I do not have time to write this code for you - as I have been asked many times in the thousands of e-mails I have received in response to this video.) You can purchase two PIC16F684 microprocessors on eBay for about $2.00 USD each. My code should be attached under "More Information" above. If not, you may e-mail me at samuelaaronward@gmail.com, and I will send you the two PIC Assembly code programs (one for transmitter and one for receiver). Please don't leave your e-mail address here in the comments and expect a reply. I will only "reply" to e-mails sent directly to me with code and other attachments. Thanks for watching!

it is a excellent project; is the ir protocol is different from the SIRC (Sony InfraRed Communication) protocol pls send me the source code to my mail pls....
