Project Design and Implementation Details

Show the connections for data signals, particularly between the Arduino, OLED, and any potential I/O expansions.
Below is a Mermaid flowchart focused on the data signal interconnections, particularly illustrating the I²C bus between the Arduino Nano Every and the OLED display, along with a placeholder for potential I/O expansion modules:

I2C SCL GPIO/Serial Arduino Nano Every OLED Display External IO Expansion "SDA (Arduino A4)" "SCL (Arduino A5)" "SDA (OLED)" "SCL (OLED)"
Explanation:
  • I²C Connection:
    • The OLED display’s SDA and SCL lines are connected directly to the Arduino’s A4 (SDA) and A5 (SCL) pins, respectively (as seen on Net 6 for SDA and Net 5 for SCL).
  • Potential I/O Expansions:
    • Additional data signals for expansion can be interfaced through the Arduino’s available GPIO or serial interfaces. Here, a generic block labeled "External IO Expansion" is provided to represent extra peripherals or modules that may use digital communication protocols.
This flowchart highlights how the core microcontroller and display are connected for data exchange and leaves room for further expansion as your design evolves.
