Connect an LCD display to the NodeMCU ESP8266 Tutorial

[@MantasMackeviciusspf]

Awesome! Any chance we could get a full tutorial? Especially at pulling out and trimming data from weather provider.

[@EZtech]

Mantas Mackevicius I made an instructable with links to the code at GitHub and new video at KZbin. www.instructables.com/id/National-Data-Buoy-Center-Weather-Display/

[@MantasMackeviciusspf]

Awesome! Thanks!

[@muzguz7276]

Nice work, thanks.

Finally someone saying something sensible on the LCD running on 5Volts

[@EZtech]

Thanks for watching, BTW I am still running the same program with the Nodemcu hooked to the LCD display for over two months. No problems!

[@Ed19601]

great. Haven't been able yet to succesfully attach LCD to my esp (01). No problems with an I2C OLED though. Just got leveladapter. Will try that one for lcd

[@EZtech]

Just remember I am using the nodemcu, you will need to make sure you are powering the lcd with 5volts. The level shifter is just for the communication lines between the two I2C, scl and sda. good luck

[@Ed19601]

yes indeed. I have seen people use it without a levelshifter. I find that too risky

[@MichaelOfRohan]

Does it though? Are you sure it wont run on 3.7

[@angelica-wn1xn]

Why I can't search the liquid Crystal library same as you?

[@RikiSipahelut]

I have a question .. Can I change pin D1 or D2 with other pin.. Thanks 🙏

[@livianandap_7474]

hi sir, can you help me why my lcd can't show the data.? in arduino ide show WARNING: library LiquidCrystal_I2C-master claims to run on [avr] architecture(s) and may be incompatible with your current board which runs on [esp8266] architecture(s). how to fix?

[@sergioivanr.p.3876]

wich library are you using

[@Dancopymus]

Hello friend EZtech! I would like your help! I did not understand what to put in buoyID; I live in Brazil, in the state of Santa Catarina, in the city of Florianópolis; How can I find this at the National Data Buoy Center? Thank you

[@EZtech]

Unfortunately I do not see a Station that is currently operating near that area, the closest one that I see has and ID of 31051 All the Buoy's that are active in South America appear to be on the West Coast. Go to www.ndbc.noaa.gov/ for a map of the buoy's

[@saurabhsakhare3328]

Hello, It's nice project. I have just a question can we put image on that display using nodemcu...

[@EZtech]

Not really, you could display special ASCII characters

[@ProjectGuns]

Hi, Great project, where did you get the correct LCD library? Regards, Stan

[@ProjectGuns]

Thanks for the link, I got it working. I am also trying to get it working with a 2.8" tft display to be able to show more information. I quit doing brens, they were just to much work to be commercially viable. I put all my efforts into doing RPD's.

[@itdropout]

How about putting coin acceptor

[@Dancopymus]

Hi friend! What is this board behind the display? Thank you

[@EZtech]

That is an I2C adapter, you can purchase the LCD with or without the I2C; however, without it - it would be nearly impossible to connect it to the NodeMCU because of the number of pins you would need to connect it. I2C greatly simplifies the project.

[@dekipet]

This will work only where stations are available? Any way to set the correct data for Serbia?

[@EZtech]

Sorry, it will only work with the stations listed at the NDBC site.

[@AbhishekYadav-pv6bl]

It's Not showing data Not showing Station I'd Serial Monitor : close connection Pausing...........................

[@noealves8400]

nice project. too bad you're not sharing HOW to get it done... a couple of links in the video description would do it...

[@EZtech]

I made an instructable with links to the code at GitHub and new video at KZbin. www.instructables.com/id/National-Data-Buoy-Center-Weather-Display/

[@AbhishekYadav-pv6bl]

Not print station I'd Speed :0 Wind speed: 0 Wind dir :0 Water :0 Wave :0 Air:0 Any suggestion

[@dandspach]

Error is here: HTTP/1.1 301 Moved Permanently Not sure how to fix though...

[@pmtsudio7869]

how to connect LCD 16x2 doesn't use I2C?

[@Pawl0solidus]

I wanna know this too!!!

[@gungman1]

LiquidCrystal_I2C lcd(0x27 ,16,2); // Set the LCD I2C address to 0x27 and screen size to 16 chars and 2 line display

[@AgachartSukchouy]

@@gungman1 no no, i mean Liquid Display without I2C input.

[@belkacemcherif9805]

need code

[@adarshpathania5600]

Bro need a code plz

[@kingfish9764]

Too many "aaahs" and "ums" clean it up. Plus your camera work was very jumpy.
