Hex file is Attached Download it and burn it on PIC12F675 it,s an easy project by using this project you can control Maximum 4 loads the loads may be your Room Light, Fan, Locker or any thing you want to control or turn ON and Off using tv remote.
Always put the TSOP1738 Sensor in a line of sight condition to work for a long range you can use any kind of TV remote which hold the 37KHz frequency standard.
whenever you press the Button on the tv remote the Led will blink Enjoy if you found any Difficulty while making this Project don’t hesitate to ask we are here to help you any time free of cost ………Thank Electronics Lovers

hi This is Murugan, this project is superb for begineers, ok i have a doubt on TSOP1738 sensor.. ok what are the value thats comes out from our TV remote. what is the digital value, how can we check the value for specific buttons. then only i can write code
This was really interesting info in this blog that to very happy for the nice technology in this blog Salsa Philadelphia classes
Dear Abid Jamal,
The above circuit sounds very interesting but to proceed I need to confirm 2 thing.
1- The input voltage required to operate this circuit? Is it 5V?
2- What is the recommended voltage of loads..means is this circuit controlling for 120V devices or for 220V devices?
Will appreciate your swift response via email me.mrangel@gmail.com
Dear Abid, Could you please confirm the input voltage of your circuit. Does it require 5V power to operate? Also please confirm the load voltage. I mean is this recommended for 120 V load or 220 V?
Please confirm. I will really appreciate your swift response.
Regards!
Yes it require 5v to operate and this is recomanded for 220v
The function of this circuit is to control the relay so with the help of relay we can control any kind of load it may be 220v and 120v
We can't download the hex file. Can we ask for a copy? Thank you!
Yes you can control any kind of loads, everything depends upon on relay the main task of this circuit is to to control the relay switching. The relay function is to Turn on 120v or 220v supply
Kindly refresh your browser, i checked the link is working perfectly. After all, if you still facing the issue so kindly contact us we will provide you a code.
thank you so much,we already got the code but can we ask a few questions on how to transfer this code to our PIC?thank you so much
can i ask if what is the use of the transistors?
sir the ic is preprogrammed? or we need to program it?
DO we have to do some adjustments if we use tsop 38438?
Good day sir, is it okay if we use tsop 38438 instead of tsop 1738?
No you need to program it by using pic debugger
yes you can use but pin configuration of 38438 is changed
yes a pin configuration
The program is not working well, all relays becomes normally close when i press button 3 of the remote.
If you like articles like this one and wish to find out some more info, I advise to read an article how does flexispy work so you can understand the mechanism of most tracking apps work
I also can not get the hex file. The browser has the latest and I have tried on four. Can I ask for this file at my address: karol263@o2.pl
Thank you!
P.S. sorry for my „English"
Dear can you add the circuit to control the speed of fan
hyy can i use my water pump in this circuit for on/off
