In this ESP8266 NodeMCU tutorial, we'll guide you through creating a versatile IoT project that connects to an NTP server, displays the time on an OLED screen, and even incorporates time-based automation, all without the need for an RTC module. By the end of this guide, you'll have a deeper understanding of the ESP8266 NodeMCU, NTP client functionality, OLED displays, and automating actions based on the time.
*Project Highlights:*
- Connect your ESP8266 NodeMCU to your Wi-Fi network for seamless communication.
- Utilize an NTP client to fetch accurate time data from an NTP server, ensuring precise timekeeping.
- Display the current time on an OLED screen using the Adafruit_SSD1306 library.
- Explore the coding intricacies behind formatting and displaying time, complete with AM/PM indicators.
- Learn how to design a smooth text scrolling effect on the OLED screen for an engaging visual experience.
- Implement time-based automation to control an LED based on specific activation and deactivation times.
- Utilize the built-in WiFiUDP and NTPClient libraries to simplify network communication and time synchronization.
- Understand the logic behind device activation based on time conditions, all within the Arduino framework.

Very nice project I am going to copy your project for my bedside table, very handy, so thank you very much for your time and effort and sharing your code, Bob in the UK
Glad it was helpful!
Thanks for your video I made it, and it worked very well it now sits by my bedside table,
I just got to set up the alarm function, but do wish it was a bit larger the display is so small, thanks Bob @@MaisonUp4049
Hi thanks for the great tutorial
i have delay of 2 hours ahead.
can i change somthing to get the Exact time.
thanks
If you want to set a time zone that is 2 hours ahead of UTC, you'll need to adjust the UTC offset accordingly in the code. Since you're ahead of UTC, you subtract the offset. 2 hours would be equivalent to 7200 seconds (2 * 3600 seconds). Here's the line of code with the UTC offset adjusted for a time zone that is 2 hours ahead of UTC:
Replace the existing line:
timeClient.setTimeOffset(19800); // UTC offset in seconds (19800 seconds = UTC+5:30) with timeClient.setTimeOffset(-7200); // UTC offset in seconds (2 hours ahead of UTC)
Feel free to reach out for further questions..
Fantastic code, thaks a lot for sharing, maybe in the near future you can weather also, but at this moment is a great job from yours, mery christmas @@MaisonUp4049
Very nice project by chance can you assist me with changing the UTC to central standard time i believe it is -6 I did try but no joy. Respectfully Kerry
I follow the recommendation, so my case is equal like you (using GMT-6), the line code change for this one: timeClient.setTimeOffset(-21600); //ofset -6 x 3600, and after 1 min is sync
Glad we could help :)
