¶ OLED Display (SSD1306)
The OLED SSD1306 display is a key component in this project, providing a compact and energy-efficient interface for displaying data such as time increments and system status. Its crisp visuals and compatibility with I2C make it a great choice for Arduino projects.
¶ Why Use the SSD1306 OLED Display?
The SSD1306 OLED display is ideal for this project because:
- Compact and Lightweight:
Its small size fits perfectly into compact setups. - High Resolution:
Crisp and clear visuals with a resolution of 128x64 pixels. - Low Power Consumption:
Consumes significantly less power than traditional LCDs, making it suitable for battery-powered applications. - I2C Simplicity:
Uses the I2C protocol, reducing wiring complexity and pin usage. - Wide Viewing Angles:
Provides excellent readability in various lighting conditions.

¶ Pinout
| Pin | Description |
|---|---|
| VCC | Power supply (3.3–5V) |
| GND | Ground |
| SCL | Clock signal (I2C) |
| SDA | Data signal (I2C) |
¶ Applications in this Project
In this project, the OLED display is used to:
- Show adjustable time increments set via the transmitter module.
- Display status updates or feedback received from the receiver module.
¶ Wiring Instructions

|---|---|
| VCC | 3.3V or 5V |
| GND | GND |
| SCL | A5 (or dedicated SCL) |
| SDA | A4 (or dedicated SDA) |
¶ Potential Alternatives
If the SSD1306 OLED display isn’t available, consider these alternatives:
- LCD 16x2 with I2C Adapter:
Simple, character-based display for text-only output. - OLED Displays (e.g., SH1106):
Similar to SSD1306 but with slightly different initialization requirements. - TFT Displays:
Higher resolution and color capability, suitable for graphical and complex outputs but require more pins.
