Hi, am I missing something here or you posted the comment under the wrong video. there is no remote in this video. we just use code to turn on different relay.

I have series of videos on remote control using arduino ruclips.net/video/muAkBQb24NI/видео.html They are from basic on how to detect the code of any remote. so first learn how this module works and have to understand how each relay is controlled. It can't be explained better. so have to know this first. then watch the video on remote controller with Arduino, detect 4 keys and create array to save each 4 code when they are pressed. this in this current video use them to turn ON/OFF relay using values from relay.

If I'm using multiple relays to power lights, can the lights be powered by the same power supply, or do they each need their own power supply? Would I need to daisy-chain them or is there a single power input that powers all the relays on the board?
Hello, i’m planning to install this system in factory. I have a basic question and will be grateful if you can answer it. My Question: a relay is rated 250Vac, 10A, if i use it to switch on/off only 100W, 0.9A bulbs can i connect bulbs in parallel and then connect them to a single relay module? if so then i can connect 10 bulbs as voltage will remain the same and current drawn will be 0.9*10= 9A which is within the relay limited current rating. will it work? is it safe?
Yes you can connect bulbs in parallel. The total load will be added and then you do the math. Check your rally rating and if the total current bus below the rates current, the you can use it.
Thank you for video please assist me can you use a push button to set times on relays for 1 relay run 14 min and you need to run 15 min to pres the button twice to record the time and when relay 2 kick in you can change it the same and let it run over and over
Hi, I have used the same concept to set up LEDs in AC supply. But during the cycle some LEDs becomes on constantly for long times and does not go off. The relay is working fine as the LED on the relay is going on and off according to program. Why..
Hello , really nice sketch , could you make a defferent : Could you write another algorithm, for example, the pins 1,2,3 light up, but 4 not wait for 5 second and then when 4 lights up, but 3 turns off while 4 is up .
I always use your relay videos to learn, thanx for that. Will you please make a video on connecting arduino and relay parallel to each other on an AC plugs. I want to leave the arduino with the relay module only. So a parallel connection, 1 converting tp DC and arduino and one to the relay and ac bulb. I am confused about the circuit design.
Sir can you explain why my relay switching operation is not working at the load side whereas the led on the relay is working perfectly according to code. Its just that the load (bulb) is not having on/off operation. Can you explain where it went wrong?
Hello, I have watched this video a few times. I am using a Arduino Uno with a Arduino motor shield. VIN is scraped on shield to prevent overload to the Uno. I have 12v coming into the Motor shield from external source. I have 5v from Uno to Vin input on the relay (The Motor Shield has the same pinouts at the Uno.) This leaves me with the 4 inputs on the relay left. So If I do as you did and ground any of those 4 inputs (IN1-IN4) on the relay, the relay will light up and and click just as your's did. Then I watched you put that same input wire from the relay to the 5v side of the breadboard, it does nothing just like yours. Fine. I got that part I believe. My question is,,, Do I leave these 4 inputs from the relay connected to a ground on the Uno. Or do they actually go another place/pin.? If you stated where the inputs from the relay actually plug into on the UNO, I must have missed that part. Which pins from the UNO actually need to be connected to the Relay's IN1 - IN4 ? I'm trying to simply control a Atlas turnout using Arduino/Relay. I saw a video once, but cannot find it anymore. You also powered a light bulb with this config, but never showed how to hook the bulb up to the relay K1 - K4 outputs. I cannot tell by the way your wires look. Since that bulb would only use two wires, I'm guessing that you have them on the closed end of K1-K4?? I hope this makes sense. Thanks
Hi, at 7:24 I have explained the relay pins. I can't believe I have not shown AC wiring in this video. Here is my other video showing that. ruclips.net/video/58XWVDnB7Ss/видео.html I will create another version of this video in a few months.
I am using 5 - 4 channel relays........ Connected separate power supply to arduino with a power bank and shorted Jd-Vcc of all relays to separate supply of 5 volt 2.4 amp but all 20 relays are not turned on instead just 6 Relay are working rest all are working if the turned on Relay is turned off........ What is the problem.......?
I want to control 4 switches in my home . I will be wiring relay board into my electricity board. My question is : is it ok if I directly power the relay board with Arduino power ? I don't want to pay extra money for a separate 5v supply . Will that be OK if all my 4 bulbs are on at a time ?
The board i got is working on 3.3 v from the NODEMCU ESP8266 board is it ok will it be stable on the long run, I read some place this board works on 5 v Dc. I do not want the board to stop working all of a sudden
When the jumper is removed (JD-VCC is disconnected form VCC) where is the common GND for Q1-Q4? Is it connected with Arduino's GND? The system is then NOT quite isolated :-(
how much current each input pin draws when they are a high? my question is can a single arduino pin be used to control all the 4 relays simultaneously on and off?
Thanks sir,Your videos are always helpful. I want to monitor the temperature and if a condition is met then turn off the power supply which is 230v/50hz.Is it possible to use the same components is it is to be used in industrial environment.Please help
you are welcome. yes it is possible as long as you don't over load it and also the arduino is properly installed and housed in a box . I would suggest to solder with wires to the bottom of Arduino pins. As just inserting wires are not reliable. Any vibration might disconnect them. So solder all wires to have assurance of reliability.
why 4 relay? what is the power rating of water pump? it is within the power rating of relay you can use only one (about 2.2KW in 220V AC ). But yes you can make all 4 parallel so they can handle 8.8KW

Hi, thanks for the great video. I have a question that I was hoping you might be able to help me out with. I'm looking at using one of these relays for some lighting, driven by an esp2866. The lights will be usually off and that would suggest that I should wire it to the "normally off" terminals. However, in the case of the microprocessor or the relay malfunction, then, I will not be able to use the normal switches (these are wired in series to the relay) where as they would work if I used "normally on" terminals. The questions is, if I used the "normally on" terminals, would I end up using more power and will it shorten the life of the relays and perhaps there might be other issues that I am not aware of? Your assistance is much appreciated.
Hi, I have separate video for relay and Esp8266 please check the right video. just click on "robojax" under this video so you are taken to the channel, then click on "videos" and then search for ESP8266 (so you learn) or click this link ruclips.net/user/robojaxTVsearch?query=esp8266

Hi Robojax, thanks for sharing. Is there relay available which trigger on high? As I don't know why but with low trigger I am facing issue in my project, using "if / else" statement. eg. I have code which reads voice command from serial link to activate relay. eg. if voice command "==red" activate relay 1(with low trigger on Arduino DO pin), else if voice command "==red stop" (deactivate relay with high trigger on Arduino DO pin) it works perfectly for if statement but not for else if. (Voice command other than red, reset the deactivate the relay again). But if I use directly Arduino pin & LED (without relay module) it works perfectly with "if/else" statement eg. voice command "red" can turn on LED by making Arduino DO high, and else if voice command "red off" can turn of LED, in this case I have to provide the specific voice command mentioned for else if statement (red off) to turn LED Off, whereas with relay module "any voice command (other thn if statement)" actuate else if statement condition.
Thank you for pointing to that. It was explained in video and I said "for example if you want to turn a relay ON if temperature is less than 65..." so anyone who watches video will know. You can remove it.
@@robojax Yes, you can edit it and make it work but that isn't the point. Your example code, in the link below the video did not compile because it had an error. It doesn't matter how many times somebody watches the video. The error in the example code will still be there lol. I see now that you have fixed it.
if you mean to push a button to start or stop then watch this video and apply the same principle to this module ruclips.net/video/7CCSRs5bvH0/видео.html
i would like you teach me, how could i make the program with a temperature sensor? la programacion es algo divertido para mi, por lo que soy nuevo con respecto a arduino.
The maximum current and voltage are different when you are using A/C vs D/C though. The relays should have their ratings printed on them. If they don't you should look it up. Usually they can handle more voltage with A/C than with D/C.
@@robojax Thanks, I understood. So basically 5V for a 5v relay and 12V for a 12 v relay is to basically magnetize the relay and you can run as high as 250v AC using the relay?
@@robojax i mean is there an earth (ground) for the AC side, as all 240V here have an earth wire for tools, part of the australian standard for electric motors

If I'm using multiple relays to power lights, can the lights be powered by the same power supply, or do they each need their own power supply? Would I need to daisy-chain them or is there a single power input that powers all the relays on the board?
for safety reasons, you should connect each relay to AC separately. If you are not sure, asked someone with experience.
@@robojax In this case, I'm using DC. Does that change anything?
no . You have to observe the rating and not exceed to current written on the relay.. Ahmad from Canada
Hello, i’m planning to install this system in factory. I have a basic question and will be grateful if you can answer it. My Question: a relay is rated 250Vac, 10A, if i use it to switch on/off only 100W, 0.9A bulbs can i connect bulbs in parallel and then connect them to a single relay module? if so then i can connect 10 bulbs as voltage will remain the same and current drawn will be 0.9*10= 9A which is within the relay limited current rating. will it work? is it safe?
Yes you can connect bulbs in parallel. The total load will be added and then you do the math. Check your rally rating and if the total current bus below the rates current, the you can use it.
@@robojax i will test this. Thanks
Thank you for video please assist me can you use a push button to set times on relays for 1 relay run 14 min and you need to run 15 min to pres the button twice to record the time and when relay 2 kick in you can change it the same and let it run over and over
Sir I want to use your relay. Can i get feedback from equipment? which is on or off. thank you sir
you must have skipped the video. when you test it, open the serial monitor as have shown in video, it will tell you which relay is ON/OFF
Hi, I have used the same concept to set up LEDs in AC supply. But during the cycle some LEDs becomes on constantly for long times and does not go off. The relay is working fine as the LED on the relay is going on and off according to program. Why..
Hi bad wiring. check it again.
@@robojax But where is bad connection i dont understand....in the relays??
try this code ruclips.net/video/Rfaz5qOLKYQ/видео.html it should work the same way.
Hello , really nice sketch , could you make a defferent : Could you write another algorithm, for example, the pins 1,2,3 light up, but 4 not wait for 5 second and then when 4 lights up, but 3 turns off while 4 is up .
I replied to your request in another video.
@@robojax Thank you
You are welcome.
3:32 Oh, so that's what the jumper was for. It took me a day, and nobody could explain why LEDs turn on but relays don't.
Good to hear that . I will reply to all Subscriber's 🔔 questions. So make sure to Subscribe.😊

Hello, I just added link to the product in the description.
I always use your relay videos to learn, thanx for that. Will you please make a video on connecting arduino and relay parallel to each other on an AC plugs. I want to leave the arduino with the relay module only. So a parallel connection, 1 converting tp DC and arduino and one to the relay and ac bulb. I am confused about the circuit design.
You are welcome.
I am sorry I did not understand what you want to do. Relay and Arduino parallel? No possible.
Thank you for this clear and easy to understand tutorial!
You are welcome. In 2 or 3 days my Udemy course is being launched.
Sir can you explain why my relay switching operation is not working at the load side whereas the led on the relay is working perfectly according to code. Its just that the load (bulb) is not having on/off operation.
Can you explain where it went wrong?
I explained it in the videos. Can’t be explained better than video. Must check your relay wiring.
@@robojax ok sir👍
Hello, I have watched this video a few times. I am using a Arduino Uno with a Arduino motor shield. VIN is scraped on shield to prevent overload to the Uno. I have 12v coming into the Motor shield from external source. I have 5v from Uno to Vin input on the relay (The Motor Shield has the same pinouts at the Uno.) This leaves me with the 4 inputs on the relay left. So If I do as you did and ground any of those 4 inputs (IN1-IN4) on the relay, the relay will light up and and click just as your's did. Then I watched you put that same input wire from the relay to the 5v side of the breadboard, it does nothing just like yours. Fine. I got that part I believe. My question is,,, Do I leave these 4 inputs from the relay connected to a ground on the Uno. Or do they actually go another place/pin.? If you stated where the inputs from the relay actually plug into on the UNO, I must have missed that part. Which pins from the UNO actually need to be connected to the Relay's IN1 - IN4 ? I'm trying to simply control a Atlas turnout using Arduino/Relay. I saw a video once, but cannot find it anymore. You also powered a light bulb with this config, but never showed how to hook the bulb up to the relay K1 - K4 outputs. I cannot tell by the way your wires look. Since that bulb would only use two wires, I'm guessing that you have them on the closed end of K1-K4?? I hope this makes sense. Thanks
Hi, at 7:24 I have explained the relay pins. I can't believe I have not shown AC wiring in this video. Here is my other video showing that. ruclips.net/video/58XWVDnB7Ss/видео.html I will create another version of this video in a few months.
I am using 5 - 4 channel relays........ Connected separate power supply to arduino with a power bank and shorted Jd-Vcc of all relays to separate supply of 5 volt 2.4 amp but all 20 relays are not turned on instead just 6 Relay are working rest all are working if the turned on Relay is turned off........ What is the problem.......?
Sir, Thanks for video. Can you please tell me how to control 4 channel relay wirelessly with FS-T4B / FS-T6B?
what is FS-T4B? you can use ESP32 ruclips.net/video/1zXlV7vmMMg/видео.html or ESP8266 NodeMCU ruclips.net/video/a8yJoeFsKWw/видео.html
I want to control 4 switches in my home . I will be wiring relay board into my electricity board. My question is : is it ok if I directly power the relay board with Arduino power ? I don't want to pay extra money for a separate 5v supply . Will that be OK if all my 4 bulbs are on at a time ?
Yes you can connect it to Arduino. I am assuming you are connecting Arduino via a USB that can supply at least 500mA.
The board i got is working on 3.3 v from the NODEMCU ESP8266 board is it ok will it be stable on the long run, I read some place this board works on 5 v Dc. I do not want the board to stop working all of a sudden
No it will not work with 3.3V. That would be issue. You need to make level shifter or add module. .
@@robojax thanks for the promptreply
You are welcome. Here is how you can change the level from 5V to 3.3V snipboard.io/gJXm0c.jpg
Can you make a ardrino relay system which consist or working on dc 12v load
? not clear. type in your language and I will use google to translate it.
@@robojax can we use 12 volt relay and same code same wiring insteade of 2 v relay?
Thanks alot for detailed & in depth video
You are welcome (after ONE year youtube added a tools to see which comment hasn't got a reply).
Thank you!! So nice and detailed explanation..
When the jumper is removed (JD-VCC is disconnected form VCC) where is the common GND for Q1-Q4?
Is it connected with Arduino's GND?
The system is then NOT quite isolated :-(
Yes. GND is common and yes it is not totally isolated.
@@robojax What then is the point of using optocouplers?
how much current each input pin draws when they are a high? my question is can a single arduino pin be used to control all the 4 relays simultaneously on and off?
Yes. Arduino can supply up to 400mA and that is enough for all 4.
@@robojax Thank you.
You are welcome.
Thanks sir,Your videos are always helpful. I want to monitor the temperature and if a condition is met then turn off the power supply which is 230v/50hz.Is it possible to use the same components is it is to be used in industrial environment.Please help
you are welcome.
yes it is possible as long as you don't over load it and also the arduino is properly installed and housed in a box . I would suggest to solder with wires to the bottom of Arduino pins. As just inserting wires are not reliable. Any vibration might disconnect them. So solder all wires to have assurance of reliability.
Sir can I connect 4 relay with water. Pump of ac current can I run without shot
why 4 relay? what is the power rating of water pump? it is within the power rating of relay you can use only one (about 2.2KW in 220V AC ). But yes you can make all 4 parallel so they can handle 8.8KW

Hi,
thanks for the great video.
I have a question that I was hoping you might be able to help me out with. I'm looking at using one of these relays for some lighting, driven by an esp2866. The lights will be usually off and that would suggest that I should wire it to the "normally off" terminals. However, in the case of the microprocessor or the relay malfunction, then, I will not be able to use the normal switches (these are wired in series to the relay) where as they would work if I used "normally on" terminals.
The questions is, if I used the "normally on" terminals, would I end up using more power and will it shorten the life of the relays and perhaps there might be other issues that I am not aware of?
Your assistance is much appreciated.
Hi, I have separate video for relay and Esp8266 please check the right video. just click on "robojax" under this video so you are taken to the channel, then click on "videos" and then search for ESP8266 (so you learn) or click this link ruclips.net/user/robojaxTVsearch?query=esp8266
I'm a bit confused as to how to control 4 AC loads with a 4-channel relay.
which part is confusing? a relay is a switch. so we have 4 swich to turn ON/OFF four bulbs or loads. simple as that.
@@robojax thanks for your reply. So what if I want to do a quadruple fan project? Do I have to wire four channels - one per motor?
Grt video sir..sir can i use this codes for doing load shedding network module...by using 3 relay
Hello, I don't know what "load shedding" is. But this is just a switch that turning something ON and OFF.
Sir i mean ki i will uuse 3 module relay connected to LEDs....i want that when my 1st relay will on then remaining should be off after 10 sec 2nd relay will be on and 1st and 3rd will be off like this ....
sir, I want to use this relay module for on-off of my air conditioner, so this relay module will work with high load air conditioner?
I told myself how come I did not explain that., I watched the video and indeed I have explained how much power this can handle. So please watch the video and do not escape. It has been explained.
If I want to use only one relay for led the what is the coding for that
Watch the video. it has been explained on how to control each bulb.
Hi Robojax, thanks for sharing. Is there relay available which trigger on high? As I don't know why but with low trigger I am facing issue in my project, using "if / else" statement. eg. I have code which reads voice command from serial link to activate relay. eg. if voice command "==red" activate relay 1(with low trigger on Arduino DO pin), else if voice command "==red stop" (deactivate relay with high trigger on Arduino DO pin) it works perfectly for if statement but not for else if. (Voice command other than red, reset the deactivate the relay again). But if I use directly Arduino pin & LED (without relay module) it works perfectly with "if/else" statement eg. voice command "red" can turn on LED by making Arduino DO high, and else if voice command "red off" can turn of LED, in this case I have to provide the specific voice command mentioned for else if statement (red off) to turn LED Off, whereas with relay module "any voice command (other thn if statement)" actuate else if statement condition.
then use the code in this video ruclips.net/video/Q9aBI4ELKC4/видео.html watch the video so you how it works.
Your example code uses temp which is undeclared...
Thank you for pointing to that. It was explained in video and I said "for example if you want to turn a relay ON if temperature is less than 65..." so anyone who watches video will know. You can remove it.
@@robojax I watched the video. Just letting you know your example code doesn't compile.
Check the code. U have updated it. If you watched the video, it should work.
@@robojax Yes, you can edit it and make it work but that isn't the point. Your example code, in the link below the video did not compile because it had an error. It doesn't matter how many times somebody watches the video. The error in the example code will still be there lol.
I see now that you have fixed it.

Yes ,on/off for specific time
With this type of relay in your video. can i control DC load ?
You can control DC or AC load. Relay has been explained in video. Watch it.
The maximum current and voltage are different when you are using A/C vs D/C though. The relays should have their ratings printed on them. If they don't you should look it up. Usually they can handle more voltage with A/C than with D/C.

How to decode any remote controller code with Arduino

Wait.....can't you only run 5v from the relay? How is he running AC for lights won't that be more than 5V?
Watch the video it has been explained. Do not escape.
@@robojax Thanks, I understood. So basically 5V for a 5v relay and 12V for a 12 v relay is to basically magnetize the relay and you can run as high as 250v AC using the relay?
Very good video, thanks !!
You are welcome.
do these boards have an earth AC connection?
you don't need to connect it to the AC ground. It should be isolated from the AC circuit.
@@robojax i mean is there an earth (ground) for the AC side, as all 240V here have an earth wire for tools, part of the australian standard for electric motors

You will need to disconnect ONE wire either live or neutral. Earth wire should be touched.
