**Here I have used the FREE plan of Arduino IoT cloud, so you can control maximum 5 relays with the FREE plan.
**You don't need any Alexa devices like Echo Dot. You can just use Amazon Alexa App for this IoT project.
**Real-time feedback is not added to the sketch.
**This sketch contains 3 files. keep all the files in the same folder.
Download Code for this Arduino Cloud NodeMCU smart house automation project from the following article.
iotcircuithub....
During the Arduino IoT cloud tutorial video, I have explained all the steps to make this NodeMCU ESP8266 smart home system with Arduino IoT Cloud to control the home appliances with and without the internet. I have also shown how to connect Amazon Alexa with Arduino Cloud to control the relays with voice commands. If the NodeMCU connected with WiFi then you can control the relays from anywhere in the world with Alexa. So with this smart house project, you can convert any appliance to IoT devices and control them through the internet.
So, now you can just say "Alexa, turn on Light" to control the home appliances.

Great project, yours is the first project I see using Arduino cloud Esp8266. Thank you so much.
Thanks
I think this is first project using Arduino IoT Cloud, after releasing from Arduino....🎉🎉
Could be. Arduino IoT Cloud with ESP8266
Good Project ! but custom design PCB from JLCPCB Price is cheap for PCB but the shipping charges are 12 times more than a PCB price
For PCB please send email to connect.techstudycell@gmail.com
@@TechStudyCell Sent an Email waiting for the reply
hello
excuse me, your explaination is not clear in terms of code. When i downloaded my code i found that switches need code but when i downloaded your code i found it is different and all pins are defined.
Thank you,
Pls add manual switch not like push button..
Or give the direction to change code
Great brother this working 🙌🏽💐💐
Excellent! Useful, helpful, clear and concise, well explained and documented, no loud and distracting music. BIG THANKS
its good to see your project
its better if you sell these ready pcb.
For PCB please send email to connect.techstudycell@gmail.com
I have done same process just like you, but at the time, when I click on discover device in alexa aap, it says no device found but shows all my 4 switches in device option, but as I turn on and off these switches, it doesn't work with nodemcu even after it is connected with my mobile by hotspot
Awesome video, nice work and very well explained. Please continue like this, I enjoy your videos very much !
Thanks for the feedback.
This is another mind blowing project you made....
Thanks
Can we use TTP223 touch switch instead of push button
Great 🎉🎉🎉👌👌. Thanks for sharing. Very very useful
Superb bro!!!!! Thanks.for.this amazing tutorial
Most welcome 😊
I don't know what the problem is but my mcu doesn't connect to wifi. I am using mobile hotspot with 2.4Ghz frequency
I am facing an issue.. When i try to control it with buttons, bulb start blinking... Means on/off repeatedly.
Please help me.....!
Very interesting project bro.👍👍
Thanks
how to use the touch sensor near the push button?
Nice video and great work, wondering the Arduino IOT cloud can also update the status of the device if I manually switch on/off ?
Sir you have done a good job but there is mistake in your code when we say turn on the light gets off and when we say turn off the light gets on in your code you have written HIGH turn Relay off and when LOW Turn Relay ON it is opposite in HIGH it should be ON and LOW should be OFF and in your vedieo you have not shown to connect the wifi credintial in our arduino iot cloud
Very useful smart home project. Thanks for sharing👍
Welcome
Bro I make a project but eap8266 node mcu is not connect the mobile hotspot
But manually is working and blynk is not working and node mcu is not connect
Pls suggest the error??
Your code is working wrong when I turn on it off and when I turn off it on. Please help me.
at the end of the video when you guide us to select the node mcu board , the node mcu board is not showing in the board section...what to do?
Very good project I like you so much 🙏
Great project congratulations
Thanks
Hello i got issue Error compiling for board NodeMCU 1.0 (ESP-12E Module).
Hi Tech Studycell... Great Projects from you... Small doubt shall we turn on lights by saying the wake word as Alexa, Go to Light one??
Ben fatto il tuo progetto... Bravo
if i control with switch what i need to change in this code sir plz let me know {when i presh switch relay onoff onoff } plz give me solution tq so much sir
Can you show if the arduino code is successfully uploaded?
Awesome project
Thanks
Excuse me Sir....

Hello. thank you very much for your many tutorials. I would like to please you do a tutorial to control Arduino leds with neural waves. neuroscience. Thank you
Noted
#define SwitchPin1 10 //SD3
#define SwitchPin2 0 //D3
#define SwitchPin3 13 //D7
#define SwitchPin4 3 //RX
these manual switches will create issue if left on/off based on different pins.. can you check and consider them?
Bro which relay do you use and with which components. Cause if we make pcb, then we can't use the relay module but instead use the relay with some components like resistors and diode. Can you tell what they are and circuit diagram for them.
What if the board blows off due to some technical problem then the manual switch also won't work then how to encounter this situation ???? Kindly help
Very good, friend!
Tks...
Push button to on|off manual switch code plz
Excellent presentation.
Thanks for your feedback

Nice project man. Can you tell me some resources to learn nodemcu programming. I am a beginner.
How Can we replace push buttons with switches
Hey, Tech Studycell can we control by google assistance How?? please answer I need Help
No. Only Alexa
mast h bhai.... is blynk going yo be paid or not.?
Sir can you please do this Same project with switch.
Sketch and things not adding in arduino code
make it with any wifi ....code without ssid and password or with wifimanger
Hey. i have a problem when i tap (on) on the alexa app realy turn( off) and when i tap (off) relay will turn (on) what is the problem?why the orders are reverse (I use exaclly your code on your website
There is mistake in the coding just change the wording in void loop from relay high to low and from low to high in the ending of the code then it will work properly
Super👌
Thank you
How to control the fan speed with it??
Sir can i get real status feedback in Arduino iot cloud app like blynk app.
Please help sir.
Sir can we use switch instead push button please
Yes. I have shared the seperate source code for switch. Refer to that.
