3. Орнотуу жана орнотуу
This section guides you through connecting the OLED module to common microcontrollers and preparing your development environment.
3.1 Pinout and I2C Address
The module typically features four pins: VCC, GND, SCL, and SDA. The default I2C address for this module is 0x3C. Some modules may have jumpers to change the address to 0x3D.

3.2 Wiring with Arduino
To connect the 0.96" OLED module to an Arduino board, follow these connections:
- VCC to Arduino 5V (or 3.3V, depending on your Arduino model and module compatibility)
- GND to Arduino GND
- SCL to Arduino A5 (for Uno/Nano) or D21 (for Mega)
- SDA to Arduino A4 (for Uno/Nano) or D20 (for Mega)

4. Иштөө нускамалары
To operate the OLED display, you will need to install specific libraries in your Arduino IDE and upload example код.
4.1 Library Installation
Install the following libraries in your Arduino IDE via the Library Manager (Sketch > Include Library > Manage Libraries...):
- Adafruit SSD1306
- Adafruit GFX китепканасы
- RTClib (if using a Real-Time Clock module)
4.2 Чыгample Code and Usage
After wiring and installing libraries, you can upload example sketches to test the display. Ensure the I2C address in your code matches the module's address (typically 0x3C).
For detailed instructions on connecting the ESP32 with a DS3231 clock module and the OLED, refer to the official DIYmall video below:

5. Кыйынчылыктарды
- Display is blank after power-up: The OLED display will appear blank until it is correctly initialized by your microcontroller and code. Ensure your code is uploaded and running, and the I2C address in the code matches the module's address (0x3C or 0x3D).
- Incorrect display output: Double-check your wiring connections for SDA, SCL, VCC, and GND. Verify that the correct libraries are installed and included in your sketch.
- Compilation errors: Ensure you have the latest versions of the Adafruit SSD1306 and Adafruit GFX libraries. Some older library versions or Arduino IDE versions might require minor code adjustments (e.g., adding `const` to `PROGMEM` definitions).
- I2C communication issues: Use an I2C scanner sketch to confirm the module's address. Ensure no other I2C devices are conflicting on the bus.
- Кубат маселеси: While the module supports 3.3V-5V, ensure your power supply is stable and provides sufficient current.
6. Техникалык тейлөө
