Remote controll tester circuit
Description.
This is a simple remote controller tester circuitĀ based on infrared sensor IC TSOP 1738. When the IR waves fall on the sensor it output changes to low state.This makes the transistor Q1 ON and LED will blink according to the code contained in the signal.So for press of each button the LED blinks in different ways.This is a good indication of the working of remote.The diode D1drops 0.7 V to give the IC ~ 5V supply from the available 6V .R2 is a current limiting resistance.
Circuit Diagram with Parts List .
Notes .
- Use a 6V battery to power up the circuit.
- This circuit can be used to test remotes operating in the 38Khz carrier frequency.Almost all remotes fall into this category so no problem.



this article is very good.but can you provide the toturial guide for all articles?.
Hi “admin”
Can you give a circuit diagramme of ‘SATELITE DIRECTION FINDER’
i need remot control circuit !!!
plz halp my i have iazam
please tell me which type of remote control circuit you need
Dear All No need go to make this circuit digram pls use ur camara mobile phone
1)on u r mobil phone camara
2)Press button remot control show the lence
3)u can look very clear IR Led Flashing mobil phone display screen

that’s a good idea.mobile cameras can sense IR and its of course the best idea.
i need a mobile locator circuit with small display could u give me?
Is this circuit enough for you

i want a remote control circuit with 50 to 100m range
it will be here soon
it is a wonderful circuit.
honerable,circuits today
I am regularly visitor of your site.i want to make a circuit.the application of this circuit is when we speak any word in this manner led will on.this project will based on the led.ex.i say “technology”in this manner led will on and i saw this word on display.
so,give me circuit for this application.and also give me program of this circuit.
thank you,

It Works… WoW
the circuits u r providing is wondrful………….
ithink it will be more if you explaian the working with each component in it.
ALL THE BEST

Once again, sometimes the most obvious solutions are staring you in the face. You are correct, if you turn your cell phone camera on and face it directly into the infra red LED’s, you will see the LED’s shining white. ***WARNING*** DO NOT LOOK DIRECTLY INTO THE INFRA RED LED’S. Prolonged exposure can harm.
Please note that the purpose of this website is education and why use something mass produced if you can build something yourself and learn something in the process.
yeah…yeah….
