Below is a condensed set of structured questions to confirm the important details, followed by a block diagram and a component list. If any questions don’t apply, you can skip them or let me know to make assumptions:
Structured Questions
  1. Power and Voltage
    • Are you powering both Arduino Nanos via a shared 5V supply (e.g., USB or external adapter)?
    • Is there any concern about powering all 6 LEDs from the same source (current draw, battery usage, etc.)?
  2. Push Button Interface
    • Do you prefer to use the Arduino’s internal pull-up resistors or external resistors for buttons?
    • Would you like hardware debouncing or will a simple software debounce suffice?
  3. LED Selection & Current
    • Standard red, green, or a mix of colors?
    • Any brightness requirements or constraints on resistor values?
  4. Arduino Interconnection
    • How do you want the two Arduinos to communicate (e.g., using two or three digital signals, serial communication, or I2C)?
    • How much distance will separate the two boards?
  5. Physical and Expansion Constraints
    • Board size constraints or form factor needs?
    • Are you planning any future expansions (more buttons or sensors)?
You can answer or skip; I’ll then finalize the block diagram and component list as needed.
Example Block Diagram
Below is a possible block diagram illustrating two Arduino Nano boards, each with its own set of I/O devices—one hosting the 6 push buttons, the other controlling 6 LEDs. The arrows show that signals from the first Arduino (the button board) feed into some form of communication or direct wiring to the second Arduino (the LED board).

Potential Component List
Below is a typical set of parts for a dual-Arduino, 6-button, 6-LED design. We can refine once your constraints and preferences are clear:
  1. Main Controllers
  2. Push Buttons
  3. LEDs
  4. Resistors
  5. Bypass/Decoupling Capacitors
    • C1, C2 for each Arduino Nano’s 5V and 3.3V pins (typical values: 0.1µF ceramic)
  6. Power Supply
    • 5V regulated supply (via USB or external adapter) with enough current capacity for both Arduinos plus the LED current.
  7. Wiring / Connectors
    • Header pins, cables, or screw terminals to connect the boards if not placed on the same PCB.
Next Step
Feel free to provide any answers or extra info. Then we can finalize the design details and confirm the best approach for power, wiring, resistor values, communication lines, and form factor. Once all is set, you can place these parts in Flux and wire them as described to complete the schematic.

Let's review the components in your project to determine if any unconnected pins might require a pull-up or pull-down resistor:
  1. R1 - This is a resistor with both pins connected.
  2. D1 - ZHCS500TA is a Schottky diode with both Anode and Cathode seemingly connected to Net 1.
  3. P1 - A pin (or connector) with an unspecified pin type.
  4. SW1 - The switch with pins P1 and P2 connected within the circuit, and a GND pin defined but not connected.
Here's a more detailed look at each component:
  • P1: Without knowing the exact function of this pin, it might be a general purpose I/O or external connection point. If it's meant to be an enable, reset, or similar input, it could potentially require a pull-up or pull-down resistor to ensure its logic level is well-defined when not driven by an external source.
  • SW1: The GND pin is not connected within your schematic. Typically, mechanical switch pins do not require pull-up or pull-down resistors unless they're interfacing directly with a microcontroller or a digital input that needs a defined state.
Recommendations:
  • For any floating input pins, consider the specific requirements of the circuit they interface with. If they're digital inputs, they usually need to be in a known state, often requiring pull-up or pull-down resistors.
  • If P1 or SW1 are connected to digital inputs, consider using a pull-up or pull-down resistor to ensure the input pin does not float, which may result in unpredictable behavior.
Let me know if you have more details on what P1 connects to, or how SW1 is used, so I can offer more targeted advice!
