Hello friends of Instructables. I am here again. The project that I bring that is more useful for the lazy.
Imagine you're lying in your bed, it's cold and you're too lazy to get up from his bed to go turn on the light of your room. Then the same bed, you pick up the remote control for your TV and connect the lamp from your room and also off with the same control. Not a good design and interesting?
This is my project! Turn on and off the lamp in his room so many appliances in your home. The project essay around the photo down there ...

Step 1: Parts

1 CI PHSC-38 (or TSOP 1738)
1 CI 4017
1 Transistor BC 558
1 Transistor BC 548
1 Relay 5V 100 mA
1 Diode 1N4007
1 red LED
1 green LED
1 Capacitor 100uF 16 V electrolytic
2 resistors 1k - 1 / 8 W
2 resistors 330 to 1 / 8 W
1 resistor 100k - 1 / 8 W
1 Resistor 100 - 1 / 8 W
1 resistor 220k - 1 / 8 W
What if no 5v relay, I have only 12v relay
What was your total cost of this project
Sorry, I can't remeber
But I'm sure that it wasn't expensive.
<p>ASSALAM -O-ALAIKUM, what is its range of working can you tell me. i will be waiting for your response.</p>
Something about 10 meters or even more. Depends of your IR light source and daylight.
<p>i cannot find TSOP 1738 in my country.... can i use pic26043sm instead???</p>
<p>Don't appear to have any problem with it. Probably usable. </p>
<p>remote (of good range) for this receiver ?</p>
<p>it is designed to use standard TV remote control or any other that has a 38KHz signal.</p>
<p>if we want to increase the output load, like from 100W to 200W or so ... What amendment would required in the circuit ?? please guide </p>
<p>Just buy a relay that fits your needs. Most common relays can handle this power.</p>
willl it trigger the relay continuously?<br /> <br />
<p>yes, it wil.</p>
Hai friend its very usefull project, in the circuit photos you displayed only 5 resistors, in the pcb layout you displayed 6 resistors, in the requirements you say 7 resistors, please suggest me what is the exact number off resistors, and what picture I have to follow, please inform me to my mail id friend, , gowthamprakash15@gmail.com <br>
Follow the PCB. I add one resistor to the first transistor to don't left the signal floating. I may made some mistake counting then.
is it possible to try this on breadboard first? <br>
Yes! Of course you can. Just pay attention to the relay: it may not fit on breadbord. I'll be thankfull you post your images
Oh Ok. Then perhaps resistors might help. Thanks! :)
Re3sistors? where? and why?
he said more current needs to be lowered, therefore a few resistors might help... but i am not using any
So you used a 6VDC relay too?
yes haha But is better to use the right voltage to don't raise amps on transistor, but as here it don't matter a lot, I used 6V relay without any problem.
How about a 6VDC 10A 120V relay?
Well, it MAY work there. It worked here. (:
can I use a 9vdc 10A 120v relay instead?
Yes, but you have to modify the circuit to power your relay. If you just put a 9V coil relay instead 5V it won&acute;t work.
nice job man!! <br>wanna ask u the input source u using is '' 5v dc&quot; but of what 'amp'?? <br> <br>capacitor C2 is of what value? <br>because your circuit diagram and schematic diagram having o.1uf &amp; 100uf values of C2 respectively. <br> <br>thnks :)
The amperage will be something about 200mA, depends of your relay! <br>And about the cap value, you can choice. Bigger values will make that the answer be slow and better, and lower values, faster answer and more failed! <br>Thank you and good luck man ;D
Hi. This is a great circuit that you have posted .I've tried rebuilding it for myself .But even after using the correct parts and rechecking their values , the circuit starts on automatically as soon as I apply the power.Could you please tell me how to stop this false triggering?
Hi. It isn't a false triggering, but it's on the circuit! Just change the ON to pin 3 and OFF to pin 2. This is normal an CD4017 start like that. My circuit also starts like that.
Thank you .This change should work great for me .
&nbsp;may I know your age?
I'm 14 =)
OH!!! I'm 15 and i dont know anything about these things. Can you teach me smething??? PLS..... sometimes on come on iternet so send me an email and wait for my reply. Email: njrajgelani4@gmail.com Thank You very much in advance
I learned all this in internet, some books and trying! Google now very thing! XD
hi,i used the tsop1738 sensor but i dont quite get how to make the insolation, so it keeps turning on and off on its own. can you help??
I don't know, but a several numbers of IR sensors have a solar light filter. The PHSC-38 have it.
is this universal??? Like can i take ANY IR code?
You can get almost all IR code
I don't understand your question!<br />
can u post a schematic for IR&nbsp;transmitter??<br /> <br />
The IR transmitter is a remote control of TV, CD player and other devices.<br />
is IC1 CD4017 is a flip flop?? will it latch the realy??<br />
no, the CD4017 is a counter. please view your datasheet to understand. bye.<br />
Thanks for your ongoing contribution.<br />I suspect English may not be your native language so I should mention that the WARNING in your last step is unintelligible to me &amp; maybe will utterly confuse others also. <br />I'd like to strongly suggest you either carefully re-word the warning or reply to this comment &amp; explain exactly what you mean..<br />Please don't be offended, I think your project is well worth the effort of tidying up such detail, thanks again.
No matters. I'm not be offended, because I now as my English is very bad. I really thankful.<br />
