| Post subject: My IR Project |
Hi everyone,
I am new here.
I plan to work on a IR-based PIC project. Honestly my knowledge for PIC is moderate but for IR, I just went thru theory without much success on practical. That's why I wanted to take this opportunity to work on it.
Hereby I have included the block diagram of my idea.
The remote control side will have some buttons for different IR signals (just like TV remote) and a LCD. When the module (consists sensors, mechanical parts and stuff) received IR signals, only it will trigger the operation of the PIC or sensors of the module. Besides the module can send information to LCD if certain conditions are triggered.
Is this possible? Does anyone willing to guide me thru? It would be greatful.  |

Good project though.
I will guide you through this project.
Tell me how you want to carry out this project.
What hardware you have ?
You want to do this project commercially or for college project ?
What is in you mind to implement ?
HOw much time period you have ?
What is your budget ?
You are only one or in team ? |

Thanks for your willingness to guide me. i appreciate it.

Basically I am still in the preliminary state, so right now I am trying to find suitable components to carry out my idea.
Right now I am concerned about the transmitter and the receiver. This is a trasmitting schematic that I found on the net and I think it's quite useful. But this schematic is for transmitting only. I plan to modify it so it can go bi-direction (ie tx/rx)
As for the TX/RX module, can I just tear out my TV remote controller (eg: PHILIP remote) and use it? Or I have to get a solely TX/RX module from Rentron or Telecolli? Any advice on this?

This is for my college side project. Student can either go for paper work which involved future technology research or practical work. So obviously I choose the latter.

I plan to use it for farming or aquatic purpose.

well there is no time limitation but as long as I can finish before my graduation, which is a year from now
| fundu_instru wrote: |

Hopefully not more than $150

No, I am alone in this project.
Basically I plan to encode/decode using PIC. The confused part is to decide which TX/RX modules attached to PIC suit best coz there are many brands out there, and I can't get them all and try out (limited $$). |

Nice to hear about this.
Now tell me why you require the feedback (i.e why you want to receive the siganal)
Kind of confirmation ? |

Oh, like for example:
I press a button, transmit signal to a sensor (for example). The sensor will monitor the situation and when it detected unusual situation (like maybe temperature too high or something), it send feedback to TX side to be display on LCD so user will know about it 
A picture is better for clarification

Which Tx/Rx Modules you have researched about?
Are you planning to use a Tx/Rx module or planning to make one using encoder/decoder or other ICs?
Interface of LCD, Keyboard, and Sensors to PIC is quite complicated and you may be able to find few application notes on micrcochip website
Do you have any PIC IC with you or still you have to decide which IC you are gonna use?
Which sensors you are planing to use?
Providing more details about your project will help us give you much specific guidance |

There are some projects on Atmel ICs on internet.
Check it.
The Atmel is quite comfortable for theis project. |

If you are familiar with PIC programming then you can attach a IR reciever such as TSOP 1738 to any free port pin of PIC for the schematic shown and use serial communication protocol i.e. the only difference is you are using IR channel instead of Wires..
In order to send a logic '1' just send a 38khz signal through IR led and for logic '0' just don't send anything..
I think you got the concept..
