Project Brainstorming for Arduino System

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.
