Arduino Clock with U8glib Library

This Arduino sketch displays a clock on an SSD1306 OLED display using the U8glib library. The clock shows hours, minutes, and seconds with hour digits marked around the clock face.

Components Used

• Arduino Board (e.g., Arduino Uno, ESP32)
• SSD1306 OLED Display
• U8glib Library

Circuit Diagram

Pin Connections

Connect your SSD1306 OLED display to your Arduino board as follows:

• VCC to Arduino 5V
• GND to Arduino GND
• SCL (Serial Clock Line) to Arduino SCL (A5 on Arduino Uno, GPIO21 on ESP32)
• SDA (Serial Data Line) to Arduino SDA (A4 on Arduino Uno, GPIO22 on ESP32)

Note: For ESP32, ensure to use appropriate GPIO pins as per your setup.

Installation

1. Install U8glib Library:

   • Download and install the U8glib library from the Arduino Library Manager or from its GitHub repository.

2. Upload Code:

   • Open the provided Arduino sketch (clock_display.ino) in your Arduino IDE.
   • Upload the sketch to your Arduino board.

Usage

1. Setup:

   • Ensure your SSD1306 OLED display is correctly connected to your Arduino board as per the circuit diagram.
   • Adjust any pin configurations or settings in the sketch if necessary.

2. Operation:

   • The clock will display hours, minutes, and seconds on the OLED display.
   • You can modify the code to customize the clock display further or add additional features.
