Introduction: Digital Clock With Arduino Uno,OLED Display and RTC Module

About: i am an electronics hobbyist.

In this tutorial we are gonna to make a digital clock with Arduino uno,RTC module and OLED display.

Step 1: Components Required

  1. Arduino Uno
  2. 128 x 64 OLED Display
  3. RTC module
  4. Breadboard(if needed)
  5. Wires

Step 2: Circuit Diagram

In this project we are using Arduino Uno,128 x 64 OLED display and RTC module.

OLED display and RTC module works on I2C communication so that both have two pins serial clock pin and serial data pin so connect the

  1. Serial clock pin of RTC module and OLED display to the Arduino pin A5.
  2. Serial data pin of RTC module and OLED display to the Arduino pin A4.
  3. VCC to VCC
  4. GND to GND

Step 3: Programming

Upload the following program inside Arduino Uno.

don't forget to include library inside Arduino IDE that is mention in code.
