Introduction: ESP8266 Network Clock Without Any RTC | Nodemcu NTP Clock No RTC | INTERNET CLOCK PROJECT

About: I am an engineering student and i just love doing electronic (mcu's) and programming (C,C++,JAVA) based projects.

In the project will be making a clock project without RTC, it will be taking time from internet using wifi and it will display it on st7735 display.


Step 1: Things You Need

Step 2: Schmatics

Follow the given schmatics

Step 3: Code

You can download the Code, Schematics & Gerber file:

After downloading the file just add st7735 library and NTPClient library into your arduino ide

Then open the NTP_CLK sketch
And before uploading the code just edit it and you need to provide your wifi ssid and password in it and then
You need to set offsettime for me it is 19800
Because my timezone is utc+5:30 so
UTC +5:30=5.5*60*60=19800
CALCULATE your timezone and edit it and then upload the code.

Step 4: Make It More Professional

After uploading the code it will look better as shown but to make it more professional lets make a pcb as already uploaded gerber file it is with code files and then i uploaded my gerber to , you can also get your pcb from there. And after soldering everything it will look like my image.

For more information watch my video to know more about this project.
