• Close all the Elements windows

Step 6: In Visuino Connect Components

• Connect "PulseGenerator1" pin [Out] to "InternetTime1" pin [In]
• Connect "InternetTime1" pin [Socket] to "M5 Stack Core" >TCP Client1 pin [In]
• Connect "InternetTime1" pin [Out] to "DeleteRightText1" pin [In]
• Connect "DeleteRightText1" pin [Out] to "DeleteLeftText1" pin [In]
• Connect "DeleteLeftText1" pin [Out] to "SplitText1" pin [In]
• Connect "SplitText1" > Text Element1 pin [Out] to "M5 Stack Core" > TFT Display > Text Field1 pin [In]
• Connect "SplitText1" > Text Element1 pin [Out] to "M5 Stack Core" > TFT Display > Text Field1 pin [Clock]
• Connect "SplitText1" > Text Element2 pin [Out] to "M5 Stack Core" > TFT Display > Text Field2 pin [In]
• Connect "SplitText1" > Text Element2 pin [Out] to "M5 Stack Core" > TFT Display > Text Field2 pin [Clock]

Step 7: Generate, Compile, and Upload the Code

In Visuino, at the bottom click on the "Build" Tab, make sure the correct port is selected, then click on the "Compile/Build and Upload" button.

Step 8: Play

If you power the M5 Stack Core, it will connect to the internet and the display should start showing the date and time from the NIST server

.You can also experiment with other servers that you can find here https://tf.nist.gov/tf-cgi/servers.cgi
