In the video, the info shows Pin4 and Pin1 are connected. It's a typo. It should be Pin 4 and Pin 8.

@JC24114 9 дней назад

Nice video, you actually don't even need 2 touch wires. Just one on each side workd for me

@supriyakarri7171 6 лет назад

Nice explanation at the end ....I have been Searching for d explaination....finally got it..tqq...in other tutorials they didn't even explain anything...by seeing ur tutorial I got it how is it working ...thax

@elonics 6 лет назад

You're welcome

@a.cousin8767 7 лет назад

very nice video :D i was just looking for 555 timer projects, keep up the good work

@kevinsigue1207 6 лет назад

hello can you give an explaination on why by just touching it can act like a switch? Thanks!

@prateekduhoon 6 лет назад

thanks mate! I was looking for one project with items that i already had!! works perfectly. I have a 4 volt battery though with 200 ohms resistors! still works

@realtrickybilly 7 лет назад

Awesome. I have tried it and it works. Thank you.

@elonics 7 лет назад

You're welcome

@pedroadaros7702 7 лет назад

Congratulations for the easy and precise explanations in your projects. You make hard matter become simple! I am trying but not yet suceeded in designing a displacement meter: combine the IR Proximity Sensor Circuit with the Touch ON touch OFF switch in order to get a "strip counter" --a paper strip with black and white lines attached to a moving object-- so I would know how many centimeters it displaced (order of 1 to 5cm in steps of 0.5cm or less ) The output should be an 7 segment LED display. Do you have any hint? Thank You

@elonics 7 лет назад

Can't think of any microcontroller-less circuit for the above mentioned application, as of now. Will update you if i get an idea.

@tajammulhussainKhadir 7 лет назад

I like your presentation more than you are Project very nice I appreciate

@tech_gadgets_maniac 7 лет назад

In the video u have mentioned connect 1 and 4 pin but u have connected 4 and 8 sir? n plzz add schematic in the description that would be helpful. As always liked ur videos a lot keep uploading more n more projects with explanation n working... thank you

@elonics 7 лет назад

Thanks Nikhil. You can find the circuit diagram here: elonics.in/breadboard-projects/simple-touch-on-touch-off-switch-using-555-timer-ic. It's in the description. Yes, I noticed that typo after uploading the video.

thank you !

@skreets3367 3 месяца назад

circuit diagram? please

@chikinskits2671 5 лет назад

My 555 got really hot. I did have the battery plugged in while building though. Should that have happened? Like I burned myself on it. And it happened within 5 seconds. (edit): I forgot resistor I will try again later

@ahmedshaker7897 Год назад

Do you know how to add variable resistance ?

@nehaparmar421 5 лет назад

What if I decrease or increase the resistance?

@haves_ 6 лет назад

how to arrange to only have one touch instead of two?

@seemakushwaha3578 4 года назад

It works but not that sensitive

@praveenreddy5187 7 лет назад

at 0.57 sec check u told that it has to be connect to pin 4 and 1 but where as u connected to pin 4 and 8 is it works by connecting like that

@elonics 7 лет назад

Correct. Its a typo. Pin 4 and Pin 8 should be connected to each other.

@YoursTrulyy 7 лет назад

what can I use for the touch probes? can I just take off the shielding on a wire?

@elonics 7 лет назад

Yeah

@isallivicura3059 4 года назад

Buenas ideas, excelente

@elonics 4 года назад

Gracias!

@sahithkumarpaka7220 7 лет назад

nice video . can i get abstract on this

@RozArialind 6 лет назад

What's the wattage on the resistors?

@HamzaQayyum 8 лет назад

Is 5v necessary, or can it be something lower?

@elonics 8 лет назад

Minimum operating voltage of 555 timer IC is 4.5v. So the supply voltage should be greater than that.

@HamzaQayyum 8 лет назад

Elonics - Electronics Projects on Breadboard Oh ok, so 5v should do. Thanks!

@sibinbabu4252 6 лет назад

@aaryankathayat2522 7 лет назад

is it okay if I use copper wire as touch probes

@elonics 7 лет назад

It's okay. Any conductor will do.

@aadhithya2047 6 лет назад

Can I use 300E resistor instead of 270ohms resistor

@elonics 6 лет назад

Yes, you can.

@KaliyanElectrical 5 лет назад

Hello sir can it work on 3.7v or 4 v battery.... Because I will make this circuit 4 my study and use 4 on/off Answer me sir......

@elonics 5 лет назад

Hi, it might not work as expected on a 3.7v or 4 v battery

@mikehauk6079 7 лет назад

uh.... that is DEFINATELY NOT pins 4 and 1...

@vatsalparmar5740 5 лет назад

How did you do the AR???

@johncoops6897 5 лет назад

Simple - type the letter "A" and then type the letter "R". Hey, I just realised that you have already worked it out.

@dazuwild4565 7 лет назад

hey bro can i add ir receiver to the on and off switch..

@elonics 7 лет назад

Wait for two days, I'll make a video on that functionality.

@ThomasKshibu 8 лет назад

Can i use resistor 1k instead of 270 R

@elonics 8 лет назад

Yes you can

@ThomasKshibu 8 лет назад

ok thanks 😚😚😚😚

@geraldinemendoza6123 7 лет назад

and can i do it in printed circuit board?

@elonics 7 лет назад

Yes, You can.

@jankishiluman1765 7 лет назад

CAn i use 9v of supply to the circuit?

@elonics 7 лет назад

Yes. Use a 1K resistor for LED instead of 270R.

@jankishiluman1765 7 лет назад

Thanks. 👍

@shafayishtiaq2990 7 лет назад

can i get complete circuit diagram of this.

@elonics 7 лет назад

@aayush3782 7 лет назад

name of the music?

@digastonluna 7 лет назад

Can I use a 12V DC input?

@elonics 7 лет назад

Yes, you can. Use a 1k resistor for LED.

@theunreservedchannel 6 лет назад

where is the tutorial?

@greekkeerg9711 6 лет назад

hi please write explanation of circuit for me ? i dont understand english, please :B no legends

@geraldinemendoza6123 7 лет назад

how to increase its sensitivity?

@elonics 7 лет назад

Without the addition of any other components, this is the maximum sensitivity you can get. If you wish to further increase sensitivity, add a transistor at the input.

@pauljosephd.mendoza2010 7 лет назад

can i use 22k and 9v battery?

@elonics 7 лет назад

LED glow will be very less with 22k. Optimally, you should use 1k with a 9v battery.

@geraldinemendoza6123 7 лет назад

can i use 9v batt

@elonics 7 лет назад

Yes. You need to use a 470R instead of 270R for LED's resistor.

@rajeshfuria2853 6 лет назад

This type of circuit with two individual touch contacts is not much useful, instead the one with a single touch contact is very much better for use.

@princessdiana8360 7 лет назад

pls show the circuit diagram of this project.

@mautkasaudagar2286 7 лет назад

it does not work pls help

@TechSE7EN 7 лет назад

theres no explaination & working of circuit on the site.

@johncoops6897 5 лет назад

Yes there is.. check the DESCRIPTION.

@giannislymperopoylos5574 6 лет назад

THE BRIDGE IS BETWEEN THE 4 AND 8..AND THE FIRST TWO PROBES ARE CONNECTED TO PINS 2 AND 3 OF THE TIMER...NOT 1 AND 2...I WAS TRYING FOR LONG T.IME TO MAKE IT WORK...I SHOULD HAVE CHECKED THE 555 PINOUT..WHERE THE TRIGGER IS ON PIN 2..ANYWAY CORRECT THE VIDEO FRIEND...OR REMOVE IT...!!!

@elonics 6 лет назад

Please take a look at how a 555 timer works and try to understand the process, before you try to explain what you did is right. The trigger Pin SHOULD be connected to Pin1 which is ground. And regarding the TYPO that Pin 4 and Pin8 should be connected, I have pinned a comment. Thanks.
