Thank You so Much for the Simplicity of Explanations and most of all for tell us What are those "words"/"shortcuts" "mambo jumbo" for us Newbies 🤣😂. Please keep us on loop with all your work 😊🤝. Thank You

[@kemaketseforkssebitiela3089]

Well done!!! Point taken well understood You're too good, precise and straight to the point no ambiguity. ❤❤

[@EnjoyMechatronics]

Thanks man

[@robertwebb9657]

Than was an excellent video on what has proven to be a difficult project for me because of Library issues. I will be following your videos because they are concise and easy to follow.

[@EnjoyMechatronics]

Thanks I really appreciate it

[@ashenskywalker5537]

this made my dht11 sensor burnout the blue plastic shrunk, i read online im supposed to have a resistor on the dht11, why dont you have one on yours and it works?

[@wesleyfredrick4170]

I was looking at getting one of these and confused how it takes both temperature and humidity using just one analog pin. So I looked at the library. It basically communicates with a chip on the sensor board, sending it commands and reading bits. In other words, it just works, don't worry silly. Thanks for making this.

[@EnjoyMechatronics]

It is my pleasure. Thanks for this information.

[@stefpauwels7112]

first thanks, everythings works expect the update on the temp en humidity. now there always stand a zero. How do i fix this?

[@computersindia]

Interesting and useful Tutorial, Thanks for sharing and providing support through comment sections. Great!!!

[@EnjoyMechatronics]

Thank you! Cheers!

[@KeithAshleyRivero]

My lcd only shows 0 on both temperature and humidity, do you perhaps know what is wrong and how to fix it?

[@BibhasMandal73]

I built it its working, I tweaked the code a bit

[@enyou2906]

How long can the 9V battery last powering that thing

[@captain-od1me]

Temp and humidity are both at 0 can you help me I already changed 0x3F to 0x27 still shows 0 ?

[@RailyAlmeron-j4v]

Hello there is no LiquidCrystal I2C by Marcho Schwartz in my Library what Alternative library should I use?

[@EnjoyMechatronics]

Write the same name and scroll down to see it or download it from the internet as a zip file, then open your Arduino IDE, click on Sketch > Include Library > Add . ZIP Library.

[@iiTzblnK]

can you do this with assembly language ? is it possible ?

[@malikthetalentmaker6001]

Quick question From where can I bring these stuff

[@ultralaggerm.e.d858]

I have a problem. So the temperature and humidity show properly, but where the % is expected to be, there isn't the symbol but some random numbers instead

[@EnjoyMechatronics]

maybe it is not supported. You could create any custom character by following this tutorial: kzbin.info/www/bejne/qGGxh3d8fpJkaZY

[@zaydhassan1069]

Hi Amazing video and clear to understand!

[@nsxamo4882]

I have a problem....my lcd display temp: 0 C and Humidity: 0 %....why 0? all parts are still new

[@computersindia]

As mentioned in the tutorial, try with 0x3F and 0x27, also try with alternative A4 and A5 pins in the Arduino UNO, the same problem was with me, changing helped me.

[@vlatkomacak89]

nice one, but project only on IDE 1.8 version work😀

[@161_abhishekmane3]

Data will automatically stored the after remove the cable from pc am j right ?

[@Zero_Two_91]

Great stuff. I really would appreciate it if u shared the code with us

[@aleksandarlazovic7390]

I have problem my code won't upload to arduino. It just says uploading and never uploads.

[@EnjoyMechatronics]

Try a basic blink sketch

[@nethumirajapaksha4284]

can u provide a link to ur code pls. i cant be bothered typing it

[@darsheelalai1241]

#include ; #include ; DHT dht(2, DHT22); int temp; int humidity; int dt = 2000; LiquidCrystal_I2C lcd(0x27, 16, 2); void setup() { dht.begin(); lcd.init(); lcd.backlight(); } void loop() { delay(dt); temp = dht.readTemperature(); humidity = dht.readHumidity(); lcd.setCursor(0, 0); lcd.print("Temp: "); lcd.print(temp); lcd.print(" C"); lcd.setCursor(0, 1); lcd.print("Humidity: "); lcd.print(humidity); lcd.print(" %"); }

[@kitkirkyen2002]

Thank you so much sir..

[@sahilraj5672]

there is nothing on lcd display after uploading the code. what to do?

[@EnjoyMechatronics]

Change the address to 0x3F or 0x27 and try to rotate the potentiometer.

[@computersindia]

@@EnjoyMechatronics Thanks, this suggestion helped!!!

[@malikthetalentmaker6001]

الله عليك يا فخر العرب

[@sanjaykhatri6093]

you code is not given in the description can you pls send me the arduino code

[@EnjoyMechatronics]

Sorry 😞 I haven't saved the code

[@techlokka4973]

gammak sudda

[@Tompok99]

D1 esp can

[@darsheelalai1241]

#include ; #include ; DHT dht(2, DHT22); int temp; int humidity; int dt = 2000; LiquidCrystal_I2C lcd(0x27, 16, 2); void setup() { dht.begin(); lcd.init(); lcd.backlight(); } void loop() { delay(dt); temp = dht.readTemperature(); humidity = dht.readHumidity(); lcd.setCursor(0, 0); lcd.print("Temp: "); lcd.print(temp); lcd.print(" C"); lcd.setCursor(0, 1); lcd.print("Humidity: "); lcd.print(humidity); lcd.print(" %"); }

[@darsheelalai1241]

This is the code... Use 0x27 instead of 0x3F

[@malikthetalentmaker6001]

Coooooooool

[@laurynasmatkus9528]

whats the code plz tel my

[@javiercruzcahuana639]

Gacias

[@EnjoyMechatronics]

No problem

[@hiddenbeauty9871]

But I don't have any result

[@hiddenbeauty9871]

Int dt =2000; This makes errors what I have written odd

[@EnjoyMechatronics]

int i is lower case
