@@robojax Hello. I have come across your channel and it interested me a lot. I have been interested in Arduino for over a year, I did some things, but rather simple.
Now, however, I had a crazy idea - heating control with Arduino. However, it is not that simple control.
That is, I heat the house with an air conditioner, a gas blower furnace. Additionally, I have a photovoltaic installation installed at home.
What I would like to do: turn on the air conditioner when the photovoltaic produces electricity. As well as at times when I have a lower electricity tariff (especially at night). Of course, in some situations, the heating is taken over by the stove.
Technically I have already turned on the air conditioner and the stove. Theoretically, I also have an idea to check whether the photovoltaic installation produces electricity.
But my problem is of a different nature. Am I undertake an idea that is impossible to perform? Theoretically, everything seems to be done, but as a person with no experience, I'm probably not aware of the problems that will arise during this project. I would like to ask what do you think about it? I know that the world belongs to the brave but ......
I am also wondering whether to do it as a control centre, where data is collected and then sent to the controllers wirelessly, or using a ready-made cloud-based system? Please, help me. Peter.
Great job, thanks! I really enjoy the humour in the out-takes, too....lol!
You are welcome. LOL
Nice one sir
Thank you.
A content-rich video. Thank you.
I have the following remark:
Most of these relay modules come with no datasheet. And critical element is the current value for the relay to function.
This is important since all the microcontroller's pins are very sensitive to the limit they can take.
In your presentation, you mentioned the 5v EXTERNAL source but did not explain why.
May I suggest a video addressing these modules that have NO datasheets and the accurate measure to perform BEFORE connecting them to the MC
Hello
The relay module needs about 60 to 80mA and esp module can’t supply that. Yes the current value is very important factor. I have separate video on relay which you have here ruclips.net/video/58XWVDnB7Ss/видео.html
@@robojax Thank you for your reply. In that video you used the Uno. The Max current limit is 40 MA.
The question is: Do I use External 5V or I keep using The Uno 5V as shown in the video. This is especilly critical in case I have the relay ON for a long time.
For UNO you can connect up to 300mA or higher. So uno can power up the relay module easily.
Thank u sir for listening to my request. Appreciate it
You are welcome. I glad it made it on time.
سلام احمد جان
وعلیکم السلام، امید وارم خوب باشی. چند روز میشود که یک کانال فارسی براه انداخته ام و یک دورۀ تددریس آردوینو را میخواهم به نشر برسانم. فقط چهار درس را نشر کرده ام و بقیه در حال تدوین اند. این هم کانال جدید www.youtube.com/@ilmofan
This was really explained well. I very much like the info being published also in your web page? Thank you.
Thank you. Yes it is on robojax.com the link to the code is in the description of this video.
I like this tutorial
Thank you very much.
Thanks for making this video
Hello Robojax. Great video as always.
I have the relay that you said would strictly need 5V to work, and sure enough yeah, It doesn't work at all in this project using the 3.3V pin. I'm trying to find the relay that you said would work with even 1V ,the one with model SRD-05VDC-SL-C. I couldn't find the single relay module, only the two channel one. Just wanted to double check that It would work fine as I'm no expert and I've found that relays are really strange when it comes to 3.3V as power.
Some videos from various channels on youtube, who are doing similar projects, are using the strict 5V relay but the Two-channel or Four-Channel ones and they appear to be working fine on these videos when the VCC is connected to the VIN on the nodeMCU. I tried that with my single-channel relay, but no luck.
Should I go ahead and order the Two-Channel SRD-05VDC-SL-C Relay? Would it work just like the one you're using in this video?
I love your work, and you're really one of the few channels that explain things in good detail. Thanks for the video, and I hope you reply.
Hello @Goldenlce, thanks for kind comment. Each relay needs about 70mA or max 100mA so 2 relays need 200mA maximum. Any of these 5V from the board will be able to power it up. The input can be triggered with anything about 1V. When we talk about relay I am referring to the module. But if you want to drive the relay yourself, please watch this video ruclips.net/video/N-fFk51Eb8s/видео.html and in case it should work. So test your without signal from ESP8266. just connect it to 5V of ESP8266 and GND and then connect the input of the module to 5V and GND to see if it turns ON or OFF. So you know if your relay module is working or not.
Hi. Thanks for the video. I'm planning to use the GPIO2 pin of an esp8266 -01. So i have to modify the sketch by replacing D1 by D4. Is this OK ?
I'm answering myself : yes it's correct. Have tried it and it worked flawlessly. Thanks again.
Please subscribe. I appreciate it and helps my channel grow. Thank you
as much as I try with my D1 mini, I just can't get them to activate the relay. If I switch over to a nano, it works fine. What am I missing?
This is very advanced project. You have to do it step by step. For example can you connect an LED and turn ON and OFF like blinking? Follow it here to turn it ON and OFF. Let's call it ESP8266 which is the chip. D1 Mini is misleading. Because this project work with all shape of the module with ESP8266. NodeMCU etc.
@@robojax I've built Alexa controlled garage door monitor/controller. I didn't think a relay would be difficult. Like I said, I can make it run just fine on an UNO, a Nano, same code. Once I move it to a D1 Mini, nothing. Lol
What if 12 volt, it will burn?
12V to connect to what? to the relay? yes it will burn.
@@robojax I seriously considered about that arduino with 12 volt will burn?
to power Arduino (not the relay), you can connect up to 20V to input jack (adapter jack). So no worries but relay works only with 5V and 6V or higher will kill it.
@@robojax
Fortunately, it's DC-DC Adjustable Voltage Booster Power Supply Step Up SET Pro . Use the rotator the resistor on the voltage regulator 12 volt to 5 volt - better help 5 volt with Relay Switch.
Selam aleyküm how can I do project with dht11 sensor at Remotexy I have arduino uno, esp8266, dht11 please help I want read humidity and temperature from my phone thank you. I did project successfully on remotexy "led on led of with cloud server"
walaikum salaam, every day I hear new stuff. What is "remotexy" some kind of service with app? It seems people want to read data in far remote locations. I will start working on offering this service.
@@robojax Allah bless you big brother its the kind of control things from far by cloudserver and really nice quality for work and I'm waiting your new videos thank you.
Jazaklalah. Do you pay for the service? For long time I have wanted to launch a service for IoT management and data processing. I will look into it.
@@robojax for button and a few switches free and I see that if you read dht11 sensor they giving 30 seconds free trial at every refresh.
@@robojax I found project but it's with internet shield of course I changed codes to esp8266 but still can't reading values on cloudserver
