Seriously every time I want to update my arduino skills I find that the bloke that seems to have something of an Indian dialect always delivers in a fast decisive manner and it's always clearly layed out with no fluff. You Sir are a Gentleman and a scholar. Another success. Thank you so much brother. Greatly appreciated. Subbed!
Thank you very much. I am Canadian, Persian from Afghanistan.
Your more than welcome Sir, my apologies for getting the heritage completely wrong . Your sage knowledge allowed me to couple the relay to a Geeetech voice recognition module. It's just a beginning phase but now I can voice activate my a bed lamp :).
Robojax you sound more like arab to me, hehe 🤣
Hi I from India could you tell me about the scope of this aurdino in electronics engineering sector

I couldn’t figure out why mine wasn’t working and now that you explained it I’m super happy, I liked your video!!
Glad I could help!
what was the problem?
Great video explaining the Songle relays. I just included them to control my train turnouts and isolation (power) tracks using an Arduino. Since the turnouts only need about 150ms of power to trigger the solenoid, these are perfect! Great job!!
Than you and good luck with your project. Thank you for not skipping the ads and keep watching it. This will help me a lot.

Ahmad, you design and build some of the most useful circuits available. Excellent channel!!
Thank you, I used this exact method to upgrade my laser cutter to automatically activate my air assist pump during a cut when activated in the cutting software so much cheaper to build a relay control box than spend £260 on a kit for the same thing!

Thanks you for Canada.
Me again, thanks to your awesome explanation, I build this! Kudos!
Thank you for posting this. I would love to see a follow up video with the Arduino controlling a relay based on input to the Arduino. In other words if I press one button the relay would be activated for one second. If I press a second button the relay would be activated for 10 seconds and if I press a third button the relay would stay activated unless a separate signal told Relay to shut off.
I am trying to control an AC motor that will raise a platform to various heights.
Simple and concise explanation, best I've seen
Thank you sir, you help to make my project work. Great lesson!

thank you so much.Simple and easy explanation. Can you post a video to connect the relay to a house circuit. eg. Light circuit or plug circuit; And which wire must we interface on. Thank you so much.
You are welcome. Thank you your suggestion. i will try to make such video in the near future.
please answer asap, how can i long the light on ? your videoa are very nice and helpful
Hi, what do you mean by "how can i long the light on" do you mean "How can I change the time the light is ON?" if so, then just add delay(2000); after the line where the light is ON. this will keep it on for 2 seconds. for 10 seconds make it 10000 (millisecond) and so on. the same way you can do it with OFF.
I can't find many people who use single relays and arduinos with AC devices, so thanks for the video! To clarify though, you said that you have to know the "load" on your device (that you plug into the relay) so it doesn't melt the relay? What if my device doesn't say? Thanks again
You are welcome. Sorry I have replied the next day and it has not been published. You should be able to find the rating. The Air conditioner, Large Pumps, Washing machine with dryer are those which are beyond the rating of this relay. Some toaster are large and above the limit. But do research online, use google image, take photo of your device and upload it and you will find the item with details.
Nice, but I didn't see the push button in the video illustration you mention in the code.
you gotta search my channel and watch it. thanks
Thank you! Total beginner here and this was very clear on the how, what and why.
I'm hoping you can help me with a question: I want to build a circuit like this, but I want to use a limit switch to turn the light on and it stay on until I push a button to reset it. I guess the best way to explain it is like an alarm. When the circuit is open the light goes on, but stays on until I reset the circuit with a button. How can I work that into this?
You are welcome. did you search for "push ON" in my channel? Here the video: ruclips.net/video/7CCSRs5bvH0/видео.html
Thanks buddy you helped me out.

Helli, I'm new on this field. I have a question, why you need to connect both the signal pin and the + pin ?
On the control side of the relay there are only 2 pins, one of which is GND
Hi, it seems you have not watched the video fully. Please watch.
is there a way to stop the relay pulsing on on power up? As in the video my relay briefly pulses on when power applied. I want to use my relay to send signal to open a gate but if everytime there is a power interruption the gate would open on power up not really ideal.
Nice video, thanks for sharing it :)
Thank you. You saved my project.

If i use the 5V relay, can I activate the 12V motor?
yes you can. Relay is just a switch. The load can be DC or AC 5V or 220V.
thank you now i can make a noise switch for a light
I am sorry I did not understand. What is noise switch?
The project is very good but i want this relay and ardunio to control water heater can i on and off heater between two temperature limits?
yes you can. You would have to use a temperature sensors like DHT11, BMP280 or something like that. I have video for both. Search my channel.
You have not said about the power adaptor jack in left corner below usb jack. Why it is not linked and explain. Why left unattended.
Hello, this video is about Relay. That jack is explained when the Arduino board is explained. You can connect up to 12V at the jack. here is the jack wiring i1.wp.com/www.open-electronics.org/wp-content/uploads/2015/07/Fig9.png
Tech RUclipsrs be like:
“Today we’re gonna build a switch”
Thank you for the information. Im an aspiring learner about arduino sir and i want to ask this question: Can i also connect a temperature sensor to this system to record the heat released of the ac bulb? The context of my idea is to create an automatic temperature control system where the light bulb turns on/off depending on the status/temperature recorded by the sensor.
Once again thank you for this awesome video!

Hi Robojax -- do you have any advice for how to set triggers for the relay to turn on? I'd like to use a keystroke with AutoHotKey to turn my relay on and off (maybe it executes a Powershell script or similar?), but I am having a hard time finding a tutorial for something like this.
Hi, here Control relay and AC bulb from Windows Shell Command line via USB and Arduino
ruclips.net/video/HzLCkzX5q3w/видео.html
which wire from the bulb is connected to the relay and how did you find positive and negative?
Please watch again. There is no positive and negative in AC. We have neutral wire and Live wire. In Canada 🇨🇦 we know the live wire and it is fixed on the wall.
What is the minimum voltage requirement for the S pin of relay
Can we connect the S pin with 3.3v or less
The operating voltage is 5V for this relay but you can get the same relay at 3.3V
@@robojax how can I contact you bro
Am developing an electronic project for my college and i need relay to complete that Project but i have a lot of doubt related to it.
plz give me your contact info so that I can discuss all doubts briefly with you
Thank you ❤️❤️
Yes you can. Use a boost converter to convert 3.3V into to 5V. Search my channel for boost
Very helpful, thank you!
you are welcome.
Do we still need a relay if our power source for the arduino is a 12v Battery (Like for motorcycles) and light up a bulb from a 12v Battery power source also?
If you watch the video, you will know the relay is a switch. If you need to turn light ON or OFF in a certain way like turn on for 3 sec and off for 8 sec then you need Arduino and the relay (or there is a programmable relay module). If that is not the case then use normal switch.
@@robojax I don't understand why the trigger pin of the relay is connected to pin 8 which is high when the writedigital value is HIGH??? At this instance, will not 5v will come from pin 8 and damaged the relay??
Thanks for clear explanation! Can I use it with DC setups as well? Thanks again!
You are welcome. yes. See the title and also I mentioned in the video "AC or DC load" . Because AC is the hardest, I demonstrated and the same is true for DC.
Awesome video tutorial. I’m a beginner. Just wanna ask if I follow your tutorial to control an AC bulb, what should i use: a High Level Trigger relay, or a Low Level Trigger relay?
Thanks. that doesn't matter which one you use. The relay shown in video is HIGH trigger.
nice
does the relay power the arduino, or does the arduino need to be connected to a USB cable while the circuit is being used?
Arduino board has multiple way to power it up. USB is one of them which powers up and upload the code to it. Relay module can be powered from any 5V source. we are using Arduino board to power it up. Arduino Step by Step course that starts here ruclips.net/video/-6qSrDUA5a8/видео.html good luck
Thanks sir
Best video
You are welcome.
@@robojax I don't understand why the trigger pin of the relay is connected to pin 8 which is high when the writedigital value is HIGH??? At this instance, will not 5v will come from pin 8 and damaged the relay??
can I use this relay in a 220V line, like in the service drop before the kwh meter?
Relay is a switch . Most relays are rated at 10A. If you are connect it to turn On/off a load not more than 10A then yea you can use it. Read the rating of the relay and use it.
ty bro
You are welcome.

Good explain sir...sir now how to connect switch mode and relay mode.like(manual mode and automatic relay mode) please explain sir.
did not understand your question.
@@robojax I don't understand why the trigger pin of the relay is connected to pin 8 which is high when the writedigital value is HIGH??? At this instance, will not 5v will come from pin 8 and damaged the relay??
@@robojax of course, digitalWrite HIGH and LOW close and open the circuit respectively. But, when close, why it's not output 5 v??? Please kindly elaborate. Thanks.
I want to run pneumatic solenoid (24 Volt DC) using Arduino....do I need a 24 volt battery for it or just a 9Volt small battery connection to the Arduino is enough?
Arduino needs it is own power so 9V will work for it. For your solenoid, you need separate power. In this case instead of bulb use your solenoid and instead of AC use your 24V.
Hi sir! Can I use HCW-M421 Timer module instead of the relay you used in your video?
Hi, no you can't. you need a simple rely module .
Thnks

Hi
I need a relay unit that can tigger on and off of a plasma cutting machine following a design from a computer system which the input is 5volts.
Thanks and looking forward to hear from you.
Regards
Hi, this is just a swtich. only you have to read the realy current rating which says "10A" and your laod or plasma cutting machine also should not exceed what is written on the relay.
Does the switchside need to be connected for me to test the relay? I am currently using a pi and it is not working regardless of what i do
i did not understand "switchside". I have not mentioned such term. we have 3 pins which I have explained and 3 terminals with screw which I have shown how to connect. This code is for Arduino but if you write your own code for raspeberry pi, it should work.
Beautiful thank you for that.

Hello, I wanna ask something... I wanna connect the relay to plug 3 pin, theres earth, live & neutral wires. So which wires do i need to cut & connect it to the relay ?
earth is for safety. You should cut live. But neutral will also work. Live is somewhat safer.
Please be careful. In AC Earth means something different. In DC earth is really what neutral is in AC. When transferring AC to DC you ignore the AC Earth.

Thanks for that! One qustion though, for some reason it works the other way around - the relay is activated (circuit is closed) for 5000ms and open for 3000ms. What could be the problem? Thanks again!
You are welcome.
This is very normal. There are two types of relays. Your relay is LOW level trigger. Meaning it is activated with LOW and goes OFF with HIGH. For this reason the code looks the opposite of what you expect.

For 2 lump be sure necessary will use 2x “5v Single Chanel Relay” or there’re other scheme?
Thanks for recording nice quide
If you want to turn both ON and OFF at the same time, then ONE relay will do it. Just connect both both wires to the same relay.
