turn on and off a LED wireless via IR

[mf1364]

Hi every body
I want to design a circuit for turning on and off a LED wirelessly via IR module and I am working on these circuit but the problem is I don't know how should I write a program for PIC (I am using MiKro C compiler and C language ) dose any body know which commands can help me for writing program ?do you think MiKro C has any library for using Infrared protocols ?

SFH 506/507 comes in many varieties for different modulation frequencies. I suspect that you need to choose one.

Common frequencies for TV remotes are 36kHz, 38kHZ and 40kHz.

Your transmitter does not seem to provide for any modulation. A small microcontroller (or at least a NE555 oscillator) may be required on the transmitter circuit.

do you think MiKro C has any library for using Infrared protocols ?

There is no IR library as standard, as far as I know, but a very clever amateur has posted some handy receiver code for some common protocols here :smile:

It doesn't

It doesn't look like be an amateur job . It's a bit confusing ! so i decide to work on this schematic at first
but unfortuenately it didn't work , do you have any advice ?

This is good
use pt2248 and pt2249a pair
and one thing for your interest
You dont need to make transmitter for this pair as the pt2248 have toshiba protocol so u just need to buy a toshiba remote
and make a circuit with pt 2249a

sorry , I didn't get completely ! do you mean I should buy a remote with pt2248 encoder ? like the pic

yes in above pic the remote kit may be contain ptt2272 and pt2260 or equilint
just purchase it
for ir
u just need to purchase any toshiba remote
and pt2249 for decoding

Thx , but I can't use module in my project I obliged to design it myself , and till know I could design a bias circuit for IR diodes in this way that I can turn ON/OFF an LED wireless , you know the output of the IR led during receiving signal is near 0v and if it don't receive signal the output is near 5v so I want to use a PIC in the receiver circuit for controlling turning ON/OFF LED so because the output voltage is Analog I should use ADC module but unfortuanetely I don't know how to use this module in MiKro C compiler and PIC18F could you guide me for writing codes ?

There is no need for a mcu here you can hook up a tsop1738 to cd4017 and turn or on off
