ESP32 Project - Digital Clock with LCD Display At Home

[@mauricio6958]

My esp32 sits on a camera extension board that connect to it's own battery, making this a useful project that don't need to be connected to Arduino IDE or computer at all. Thanks for explaining this in such detail. I'm in California and it took me awhile to figure out how many seconds to adjust gmtOffset_sec for my zone, but it's working perfect now.

[@EnjoyMechatronics]

Sounds great!

[@Platttraining]

Outstanding video and very detailed. I can see using this tutorial in my American High School classes. Thank you so much.

[@EnjoyMechatronics]

Glad it was helpful!

[@Hrudayesh]

Sir I am using the same library as you mentioned but no text is displayed. I tried adjusting the contrast. It works with Arduino UNO and not esp32. Please Help

[@cbara568]

Any tips for a casing that can hold all this stuff and display the LCD1602 nicely?

[@michaelrydahl8669]

Is it possible to stop flickering on lcd at the seconds update?

[@EnjoyMechatronics]

Yeah it's possible using millis()

[@GarlicMonoxide]

excellent video, the explanation and presentation is perfect. great attention to the details that matter.

[@EnjoyMechatronics]

Glad you liked it!

Boardnya menggunakan NodeMCU-32S ya ?

[@ingoknoppke7265]

Cool project! How to assign the &timeinfo for %H, %M and %S to variables of type "int"?

[@תומרגופמן]

char timeHour[7]; strftime(timeHour,7, "%H:%M", &timeinfo); return timeHour; it will return a string but u can convert it. U can paly with the format but u need to change the length of the array accordingly

[@aryanwasan2654]

any alternative to i2c?? i dont have one

[@MrBobWareham]

Very nice project and looks good, but would like it for my bedroom so how can I auto adjust the brightness please.

[@EnjoyMechatronics]

Thanks 😊 It's a great idea to add auto brightness by using an LDR (photoresistor)

Bro is it possible to modify the normal digital wall clock into ntp synced clock. Check with Al fajr clock CW-05 model no.

[@peteygnyc]

Does not compile. :( Trying to use with Lolin D1 mini clone, and 2004 lcd display. Changed variable for screen, I have the right board selected with com port. A ton of errors when compiling. Just trying to make a simple NTP clock with time, day, date. :(

[@waka7377]

que pena, a mi me funcionó a la primera después de configurar la pantalla 0x27 y el offset UTP

[@vegasdealer777]

Thanks for your nice video. I'm using a NodeMCU-32s (HiLetgo), with your "Hello" program, but I'm using a 2004 LCD. I get this error: ============ Multiple libraries were found for "LiquidCrystal_I2C.h" Used: C:\Users\junkg\Dropbox\Programming\Arduino\libraries\Newliquidcrystal_1.3.5 Not used: C:\Users\junkg\Dropbox\Programming\Arduino\libraries\LiquidCrystal_I2C exit status 1 Compilation error: invalid conversion from 'int' to 't_backlighPol' [-fpermissive] ================== I can't even FIND this Newliquidcrystal_1.3.5 on the list of installed (or not installed) libraries. What am I doing wrong here? Is it because I'm operating out of Dropbox?

How can I convert hour number to int and use it in a conditional loop?

[@wabda-2003]

Can we please get the code

[@waka7377]

ordenado y funcional, que mas se puede pedir, gracias

[@HobbyHomeWorkshop]

My ESP32 no longer connects to WiFi. I did a test, without LCD, it worked. Then I uploaded the program with LCD and it doesn't work, but now the code without LCD doesn't work either. I can't explain this.

[@cesarsolis001]

Esp32 gpios work with 3.3v and i2c module works with 5v so u need to manage the voltages with a voltage converter

[@VIRUSSS007]

how to do it with esp8266

[@pflint]

great video

[@EnjoyMechatronics]

Thanks!

[@Draven805]

could you make a digital screen connect to a specific website?

[@finn3163]

you can get data from the api, but you cant display a website itself on the screen, as theres no browser running on the esp32

[@Anandkumar-mb9bi]

Hi, if I want turn on led on 6 am and off on 5 pm with this real time,? Is it possible, please send the code I need it.

[@EnjoyMechatronics]

It's definitely possible.

[@Anandkumar-mb9bi]

@@EnjoyMechatronics Can You Guide me the Way, please...

[@ihmSelbst]

@@Anandkumar-mb9bi like: if (time.hour() > 6 && time.hour() < 17) { digitalwrite(PIN, HIGH); } else { digitalwrite(PIN, LOW); }

[@md.mijanurrahman8344]

i got an error lcd.init(); not found in library name.

[@ihmSelbst]

you habe the wrong library.

[@michaelrydahl8669]

Use lcd.begin(); and it works

[@waka7377]

the library es LIQUID CRYSTAL I2C

[@suchin04]

Good idea

[@EnjoyMechatronics]

Thanks

[@GudepuKavyasridurga-em9ch]

can we get code

[@Youtubeshorts-kg4hy]

Make video on send time and data to firebase

[@EnjoyMechatronics]

OK thanks

[@Youtubeshorts-kg4hy]

@@EnjoyMechatronics your video really helped me to print time on serial monitor but I got a confusion regaring the UTC, if my local time is UTC+5, I have to add 3600 or multiply it?

[@EnjoyMechatronics]

@@KZbinshorts-kg4hy 5h*60*60 = 5*3600=18000

[@chandanpandey3428]

Not working

[@EnjoyMechatronics]

Use another address like 0x27 not 0x3F
