Help with IR Receiver

[janosandi]

I have a small Remote control unit Which i need to use the transmitter & make a receiver for it
its only one button transmitter
would you plz advice me to where to start
Thx Guys

Hi,you can used infared reciever sensor then connect the output to a monostable circute using NE555, make sure you power the sensor with 5volts, then used your output at pin 3 .

At first u have to check on which frequency u r working upon.like say you ir signals a frequency of 38khz then u can have a special sensor,t-sop 1738 that will sense only the provided signal on the receiver part.

connect your timmer IC NE555 output 3 no. pin of monostable configuration to ir led in the transmitter part.like wise to hold your input from the t-sop in the receciver,with purpose of ur makin,you can use JK or D flip flop as memory.

Hello

I've found ready made circuit with pic 12c509 Which it record the button click of any remote control then use this button to control one ouput
anyone have an idea of this ?
ur help will be appriciated

The idea is as simple as you got it. Just get the code from the TX, and decode it and switch a relay. Rest of the complication lies in the 12C509 which is a microcontroller and code written and programmed in it. Except you get the code, no one can explain in detail about what exactly is done by your circuit.
And as you tell, the receiver cannot respond to ANY remotes REC button. Because there are quite many ways to encode the remote transmitters which again lies in the source code. The receiver will respond to only a particular types of remote handset for which it is specifically programmed.

Thx But i need a program like this to program the pic if u have an idea when i can get it

Hi janosandi,

First you can recode the bit pattern emitted by your transmitter.(You have to have/built IR receiver unit that can store bit pattern in a memory)

Next use that bit-pattern to compare with any received IR signal; if same pattern is found generate an output signal. For these tasks you can build IR receiver with a PIC.
