Using this project you can easily display the time for other time modules like RTC DS1307, DCF77 or Internet time.

This project was made by Visuino user Rafał. Visit his youtube channel here:

Step 1: What You Will Need

1 / 4

  • Arduino UNO (or any other Arduino or ESP)
  • 20X4 LCD I2C Display
  • Jumper wires
  • Visuino program: Download Visuino

Step 2: The Circuit

  • Connect LCD Display pin [SCL] to Arduino pin [SCL]
  • Connect LCD Display pin [SDA] to Arduino pin [SDA]
  • Connect LCD Display pin [VCC] to the Arduino positive pin [5V]
  • Connect LCD Display pin [GND] to the Arduino pin [GND]

Step 3: Start Visuino, and Open Attached File

1 / 3

Below is attached file for this project that you can open in Visuino program.

Step 4: Generate, Compile, and Upload the Arduino 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 5: Play

If you power the Arduino module, The Display will show the CPU Time.

Congratulations! You have completed your project with Visuino. Also attached is the Visuino project, that I created for this tutorial, you can download it and open it in Visuino:
