Hello brother, thank you for your effort. I want to use this circuit to turn on and off the parking lights in cars. How can it be used? Is another relay added or the same circuit used?
Can i use this timer for beam sensor,v for increase the alarm response time
Dear Mr. Ahmed it is great explanation as per my understanding this time delay for circuit off ( ie circuit switch off after predetermined time ) I do not no if can modify such circuit to be delay for circuit on ( ie circuit switch on after predetermined time ) best wishing and regards
Sir you are best teacher
I am glad to be helpful.
Ohh cool
LOL
Sir I hoppe you can answer my question I like to use hv ceramic capacitors with my hei ignition system series of capacitors soldered together and I place it any where on my e core ignition coil mostly coil + side the other side I ground to chassys or wia some trip switch .
Now the problem acured my car is 80s Opel it has the Delco 12si alternator I think its A circuet alternatir I use only pin 1 with light bulb the other pin 2 isnt used I do not have any diodes in my car only bulb when ever I use those multipel 3 kw capacitors in seies my alternator starting charge gets displaced so my alternator constantly back feading true the bulb unless I give it more revs and the alternator starts charging my baterry and the alternator light goes off but If I run on normal idel speed the bulb turns on again .
So can you tell my please what thoes capacitors have to do with the alternators voltage regulator amd how can I counter this strange effect?
How much I culd understand inside my alternator regulator I found miniature ic chip and 2 small capacitors how much I culd understand the ic chip is also baterry negative voltage potential controled some sort of?
So how to chuse capacitor or value to counter this effects?
I have lot capacitirs resistors and 500k potenciometer also have insulated alternator voltage regulator screws but dont know how its calculated out come that my alternator charges in what rpm ranges.
So I hoppe you understand my question .
So Im not shure what to use honestly resistor/capacitor box ,cloosed loop voltage regulator Im still cinde of woried to over charge my baterry
👏👏👏
Thanks.

I want to convert this module to 5v ,
And use 3-32 v npn sensor to restart timer,
Input power supply regular on ,
Bro tell me how can I do ,
JazakAllah
Good
Thanks
Sir i copy your video and share on our chnal but you gevme permission to i convert in our league
Hi! Great video! I will add the reset button, but how many amps will relay handle for 12v? I want to use as a kill switch in my vehicle to turn off 10A starter fuse. Tnanks!
Hi, thanks. it seems you have directly jump to this video while I mentioned that yo have to watch the introduction here czcams.com/video/RjWW4nbUyio/video.html
Use this relay to operate auto relay
@@anthonysleight9244 Thank you!
👍👍il serait intéressant de lui ajouter une extinction automatique du module une fois le décompte fini 👍
possible. but it would need another switch to turn it ON again.
Hi, excelente explain, thanks ... I have same module but as delay on mode ... Can you explain how to change to delay off mode
For the load just connect it to the middle and other connector of the relay and the operation will be reversed. Instead of On it will OFF
@@robojax Thanks for quick response!
Obviously I was not explained right, sorry for my english...
My module work opposite than yours. When I turn power on after couple of seconds (after desired time delay) the relay turn on and green light is on unlimited time. On your video it is opposite, after turn power on or push the swich you have desired time delay for relay and green light turned on after that it turned off.
Can I do something to change operation mode as on your module?
Thks for subscribe
Hello. I'm not sure if you can suggest a fix for my situation. I have a 2005 Dodge Grand Caravan. The rear intermittent wiper motor, when turned on pulses the wiper every 6 seconds. This is very annoying. Can what you are showing help me to control an increase in time between impulses. Ideally I'd like the rear wiper to pulse on between 30 seconds and a minute. Thank you
Hello, you can't change that timer. but you can change the continuous operation by putting this relay on the path of motor wiper.
Kindly I request you to provide sketch for this best regards
hi, how about adding proximity sensor switch?
Hi, use any switch that creat the same high or low state.
Hi, I followed the wiring for the switch minus the additional capacitor but not resetting. Mine module seems to work opposite yours. Only one led on until it reaches time then both on, while yours starts with both on and turns off. What's going on there?
then either your module is different or you've connected the load wires different. I am not sure.
I have same module.
Our modules are different
I'd like to make a delayed start signal for a project but I can't wrap my brain around these timers offered on Amazon.
I have an inverter (Schneider Electric XW+) that will use a battery bank to power my critical loads. It can also get power from a generator that it will start when told to do so.
I want to connect a 12vDC relay to a power adapter connected to a grid outlet, that is, not a critical load outlet. When the power goes out the relay will switch and the normally open connection will close. That's the trigger that the grid power is out.
That trigger needs to delay start the generator after grid is down for 15 minutes by momentarily closing a connection on the inverter. However if the grid comes back up before the 15 minutes then everything is canceled, that is, I don't want to signal the inverter to start the generator.
Another delayed timer relay is to stop the generator after the grid is up for 15 minutes. If it comes up and then down again before the 15 minutes, then nothing happens. But if the grid stays up for 15 minutes, (12vDC relay connected to grid power adapter is on), then a different connection on the inverter is momentarily made signaling it to stop the generator and return to using grid power for the critical loads.
Any thoughts, comments, ideas, etc. will be appreciated!
Thank you
V NICE EXPLAIN 👍👍👍🙏🙏
Keep watching
why my time delay won't work if the electricity gets cut out and immediately return, I want to use it as a surge protector but with this it removes it's purpose...
Hi Robojax, is it possible to make a hack for battery-powered lamps?
The timer module is not connected to the voltage. Only when the push button is pressed, the module is supplied with voltage via the relay and after the time, everything is disconnected again. So the lamp and the module do not need any power. Is that possible?
Hi, we have control system and the lamp. Relay and controller must have power available to them. They simply disconnect the lamp.
😍
😊 ❤️
Hi,
Is it possible i can use a limit switch instead of reset switch. And as soon as the limit switch is pressed, the power is cut off, and after 2 seconds the power starts again irrespective of limit switch is kept pressed or depressed.
Thanks
Hi, this can't do anything else. see other modules czcams.com/users/RobojaxTVsearch?query=Timer or Learn Arduino in 30 Minutes (video): robojax.com/L/?id=135
Assalamualaikum i am from Indonesia

Hi Robojax, I need your knowledge... I want to have a module which I can connect to my computer and adjust it on there, and set the time between 0-1 second, so i want microseconds... Or adjust the microsettings with my phone, what module do I need? thanks
hi, you need Arduino with relay. I have tones of videos on that.
@@robojax also microseconds? You have any links to one of them?
You were talking about relay which can never be turned on of at microseconds. Relay is very slow like I.2 seconds
@@robojax i need something which is very fast, like 0.1 seconds or 0.2 seconds
relay is not good option for that. relay is mechanical switch and I am not sure if it responds at 0.1s very well.. if you control DC load you can use mosfet and if you control AC load then use TRIAC to turn ON or oFF quickly.
What capacitor would it take to increase time half an hour?
It is R times C but I did not try it. So experiment with different size. Once you find time for a certain size then you know the what size to capacitors to use. Is simply try sizes.
I people I need some help 😢
I have that module and I think they never work (relay and green led) try same circuit 12v for lamp.
how do I fix it and make it loop 10sec on 10sec off ?
Can’t do loop see this czcams.com/video/81XzLwt3dqo/video.html
if i turn off the main power and turn it on again the relay will start working directly whit out press the button right ? than how i make relay run by just pressing the button even if i restart the main power ?
yes. Use Arduino. forget about this czcams.com/video/6DGQhQgr7Ak/video.html or this czcams.com/video/BhEIFzFSMuE/video.html
@@robojax thanks for reply 😊🌹
How about adding a PIR sensor to activate the relay? Can be done?
Hello, yes watch this video czcams.com/video/mZCJNOf69JI/video.html and instead of Arduino, connect it to this module. I believe it should work.
@@robojax I shall watch right now
@@robojax maybe wrong video, it's about arduino connection
that is correct video. you learn how the motion sensor works. the sensor simply outputs voltage and you connect it to this timer instead of Arduino. if trigger level is the opposite of what you expect, then make circuit like this snipboard.io/vERWPt.jpg to change HIGH level to LOW or in reverse.
Correct me if i am wrong, you increase the charge capacity by parallel capacitor, so it will take longer time to charge the capacitor?
the larger the capacitor, the longer the time that holds. Yes.
@@robojax Something wrong, the relay went on and off very repeatedly, sometime it's duration became shorter, seem like not enough current.
Can you please explain what you mean. Thanks
First of all you are watch the wrong video. Please watch this video czcams.com/video/RjWW4nbUyio/video.html and instead of bulb shown in the video, connect the positive wire going to the motor of your wiper. this will work when you set the wiper in continuous mode and this module will intervene and turn ON or OFF at interval required. I am sorry I can't explained better than this. See also this image snipboard.io/AHhRpV.jpg
Hello sir, nice work for time increasing, but I want some more, I have a request to make video about how to convert this (off delay timer relay) to (on delay timer relay) that actual gives output after the time ends.
Relay has 3 connectors . Keep the middle wire connected. Move the second wire to the 3rd relay connector
@@robojax Actually I want to change the output to open after delay( not the NO and NC of the circuit) and thanks sir for faster reply, you are very kind, who replies on a video published 3 years ago
Dear Mr. Ahmed please provide circuit diagram for this module best regards
Hi, as simple search for "555 timer circuit diagram" showed this www.circuits-diy.com/time-delay-relay-using-555-timer-ic/
How to do it: when the first trigger signal causes the relay to close, if the waiting time has not expired, if we add another signal, the module will only reset the time without the relay opening. Until the last signal's waiting time expires, the relay will open.
Hi, may be you need a device like this Home Automation: How to use 7 Program 0.1s to 9999 minutes Relay Timer XY-LJ02
czcams.com/video/s4oNCpH_I0E/video.html and I have more videos on different modules, just search
Hi, how are you connecting the push button switch to the circuit??
Hi, it is shown in video and that’s why I made this video
@@robojax OK, thanks, the reset switch is the same energizing switch, right?
we have one switch and whatever you call it.
Thanks man
It seems that there are two versions of this module. One that is ON and then it shuts OFF after timer and one that is OFF and turns ON after timer. On the first video you have second one and on this video you have first version. It's strange that there is second version since then relay is on all the time and you still have NC and NO open connections. Anway since this video i managed to rewire mine to put capacitor in place of potentiometer and potentimeter in place of capacitor.
Robojax should pin your comments as the top comment. From what I've read in these comments you're the only viewer that understands how this chip works. Including Robojax. Sadly, it's buried down deep in replies. You're absolutely correct in your assessment of this board. The logic as it configured is ass backwards. I've worked with the 555 for over 49 years and have never seen one wired like this one. It's absurd to have a board that spends 60 seconds with the relay de-energized while the rest of the 24 hour day the relay is energized and the board is powered on! WTF? Surfing through the data sheets I think anyone would be hard pressed to find Rt tied to GND and Ct tied to Vcc! It's simply unorthodox and inefficient. My 555 project is intended for a self cleaning (60 sec) filter cleaning cycle for my shop vac. Note: For fast recovery (re -trigger) add a reversed biased Diode across 'Rt' timing resistor. It speeds up discharge of the timing cap 'Ct'.

I asked for help about why the push button reset does work. It is connected just as you describe in this video but it will not reset. Please help!!
It must work if you do it properly.
What will happen if i press and hold the reset button? Is the time will not run?
It will be on . I believe I have shown and pressed it. When you release the time count down starts
I have added a capacitor so IC is heating what is problem& solution
capacitor is should not do anything. you must have connecting the + and - in reverse. Capacitor should explode if you connect it in reverse.
I heve using 470 uf/35 v capacitr with polarity pl. Solution
Sir
May I get circuit diagram?
Not available.
I dont understand on fixing reset switch please explain again
It is done. Play it 2,3, or 4 times
1000uf 50v and 1m after remove trimpot increase 10min
How do you increase the time to 60 seconds? Thanks
That is exactly why I made the video to tell
@@robojax With 220 it goes to about 40 second. What would.it take to go to 60 seconds?
I did not calculate it. just experiment. the capacitor size is unknown.
Please did you knew how to do this
@@sorenweisshartmannPlease did you knew how to do this
Can i make it 2 hours???
Anything you like. Just add larger capacitor
Where is trigger pin connected?
You have skipped the video. Please watch fully
@@robojax extremely sorry sir
Video was very helpful
I try it.but push button is not working.
You just have done something wrong. Check again
Sir
Where is pin 7 connected?
I don’t have the board , just look at it from both side and use multimeter to figure it out. Also look at 555 timer datasheet you easy read it.
In this use of the NE555, pin 7 is not used. It is the discharge pin for a timing capacitor. In an astable multivibrator circuit it would be used to discharge the timing capacitor to continually repeat the charging cycle. In this case the NE555 is used to create a monostable multivibrator (Also called a "one-shot") so pin 7 is simply not connected to anything.
Rest not working
Working . You are not doing right . I have shown on video . Watch again
