Thank you

[@anandjoshi8554]

​@@TechStudyCell 1. will this circuit keep the load/tap On, when IR sensor goes ON off momentarily while hand wash is continue in sink ? 2. as I want only 3- 6 sec off time delay , should I use 10k or 100k preset vri resistor ?

[@anandjoshi8554]

@@TechStudyCell Can ne555 timer relay module be used for OFF delay also > for both activating the load and hold/maintain its ON position up to specified time (0-10 sec) ? in a IR sensor +ve output circuit ? triggering on off again and again by IR sensor output ? as I am annoyed by the on off flickering Output of IR sensor relay circuit and its sound while using it as automatic sink/basin hand wash process, as hands sometimes goes away from IR leds.

thank you man , it's working well. I tested it and it's have a good accuracy as a kitchen timer ( ± 1.5% )

Good day. Your videos are suggested after our videos. We don't know why, but we send you nice greetings from Berlin.

[@S_e_r_g_ei]

I'm watching from Russia. Well done! Simple and clear! You can modify it a little and make a similar circuit completely for 220 V. Then it will be a pulse relay with one-button control! The author, instead of a mechanical relay, it is much better to use a triac. After all, as a key, a triac is much more reliable than a mechanical relay! And you can make power for the chip from a low-capacity "quenching capacitor", a bridge, a smoothing capacitor and a Zener diode to the desired voltage. Try to refine it according to this principle, then I will adopt Your scheme! And yet, there should always be a standard scheme! Preferably laid out separately or in the video itself, at least for 5-6 seconds. Then it will be considered a full-time job, and this is already professional and high-quality! Then you will want to watch something else on Your channel again! Sincerely from Russia! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Смотрю из России. Хорошо сделано! Просто и понятно! Можно немного доработать и сделать подобную схему полностью на 220 В. Тогда это будет импульсное реле с управлением от одной кнопки! Автор, вместо механического реле, намного лучше использовать симистор. Ведь как ключ, симистор намного надёжнее, чем механическое реле! И можно сделать питание для микросхемы от "гасящего конденсатора" малой ёмкости, моста, сглаживающего конденсатора и диода Зенера на нужное напряжение. Попробуйте доработать по такому принципу, тогда и я возьму на вооружение Вашу схему! И ещё, всегда должна быть стандартная схема! Желательно отдельно выложенная или в самом ролике, хотя бы на 5-6 секунд. Тогда это будет считаться полной работой, а это уже профессионально и качественно! Тогда, захочется снова и ещё что-то смотреть на Вашем канале! С уважением из России!

is it possible to switch off regardless of the time the pushbutton is pressed (in case I had a coil instead of bulb so that no matter how long the pushbutton is activated the coil will disconnect after say 1sec to avoid damage)

[@ashvineekumar6347]

What should I do to reduce the delay time from 15 milliseconds to 1 minute with a variable resistor??

[@g2257]

Yes, you can calculate this using 555 equation: Delay time=(1.1×R2 in ohm)×(capacitor value in F)

[@ikanjaws2671]

Hello sir may i know how to set to 3 minutes? And can i change the 12vdc to usb ?

[@rachid746]

To set the time to 3 minutes you should put a higher value resistor for the timing. to change the power to 5v you need just a 5v relay. all other components are fine with 5v

[@gokulkarmakar7265]

Thanks, Your Video Is So Helpful for Me

[@sitiaishahhusnamohdnoor6825]

[@aldiepradana44]

Hi, can you make 0.25 second? / 1/4 second

[@Dabaiko]

Would this work if the input was 5V? (Assuming a 5V load instead of the relay as well)

[@kennmossman8701]

read the datasheet 5V is rather low some have had problems at 5V check the CMOS version what current does the load need???? ALSO not thet the 555 output voltage is 1 to 1.5V LOWER than the supply voltage

[@Lotrfan1991]

Would it be possible to make this work for 1 hour?

[@kennmossman8701]

doubtful the current would be too low and fail due to cap leakage - use a decade counter after the 555

Hi me too asked the same. they haven't answered yet if you already found the answer let me know plz...

It's the capacitor slowly discharging after being charged up with the button press, it's an extremely basic 555 circuit. Google other NE555 circuits for ideas

[@ashvineekumar6347]

Bro I watched your videos, its really very osm, easy to learn and make diy projects. Anyway. Can I use this circuit as spot welding controller??

[@kennmossman8701]

yes but a relay probably would fail since the peak current is extremely high. Plus a relay is less precise in turn-on/turn-off

It will help at the tactical range. I'm printing the body when I get my circuitry handeled. I haven't gone to electrical circuitry class for 15years, but recently just aquired soldering equipment and components... just getting back into things.
