04 Easy IoT project w/ Arduino IoT Cloud - ESP32 | DHT11 Humidity & Temperature | Relay & DC Motor

In this video, Joed Goh teaches you how to build your first IoT project using Arduino IoT Cloud with ESP32 thing. You'll learn how to read and visualize temperature and humidity data from a DHT11 / DHT22 sensor and control a DC motor / AC electric fan using an SPDT Relay. You'll also learn how to conduct your own experiment on how to control the brightness of an LED using a Dimmed Light widget in the Arduino IoT cloud web and mobile dashboard.

The best tutoriel i've ever seen!

[TECHMONY]

great teching sir..resfect thank very much

[fjdelahoz]

Well Done. I enjoyed your video very much. Everything is nicely explained. Congratulations !!

[venkatakrishnansrinivasan]

Very clear and Extra ordinary tutorial ! Thank you !

[nurniza]

in this project what about data ...everytime we turn it ON or OFF ...is there any place the data save

[maheshmustapure]

Hii sir
Thanks a lot for such a beautiful lesson
Education is

[acefuzzball]

Hi Sir i have question
how can i control relay manualy and using automation?
for example, control relay to turn on/off fan using webserver and using TTP223 touch sensor, i tried and it doesnt work together i can only use 1 of that for control relay

Thanks. How to choose esp wroom 32 (30 pins) for IoT projects ?
It does not exist on the board options.Which board I need to choose from the list ?

[azzuhairizahir]

If i use 12 volt battery supply how much value of resistor that i have to use and also i use 12 v dc motor and 0.3 A

can you make a Iot cloud with esp32, capacitive soil moisture, dht22

[wonderwang]

I love this channel! It is clear and the purpose is true, education is life

[marygamal]

can i use Arduino UNO and ESP8266 instead of ESP32 ?

[attic]

Hello great video!
But I am wondering, if it is possible to make real time charts showing actual values and alao historical data, also presented by charts and available online anywhere.
Example project: weather station, electricity metter.

@joedgoh
Its amazing video brother.. I need to know that if we wanna add soil moisture sensor along with the same project and set the specific range so the motor should start automatically. Is it possible to do? and how can we achieve this. If you add it in the same project then it will be a great help and I will really appreciate. Thank you

[captainandre]

Great video thank you. I can’t get the arduino connect to see my ESP32. Any idea?

[jaikrish]

Sir i need one help how to modify and write code with DHT sensor and relay. Whenever the temperature is reaches above 35° then the relay will On state, and whenever below 35° relay will Off state. Also monitor in Arduino iot cloud platform using esp32. Please help me sir...

[maheshmustapure]

I am trying to use MAP of arduino iot cloud
But it's showing latitude 0 and longitude 0
As they are initial values
What changes in code are expected for proper location ?
Thank you...

[ajinkyaudamale]

Can you please make video on Arduino cloud iot and x9c104 digital potentiometer

[jasonchua]

Hi, the instruction and sketch is clear on your channel. Could you provide the code for dimmer light, thanks
