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.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Things You Need
Buy ESP8266/Nodemcu :
Buy 1.8" SPI TFT ST7735 dispay :
Buy USB Cable for programming :
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
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 https://jlcpcb.com , you can also get your pcb from there. And after soldering everything it will look like my image.
