Voltage and Current Monitor

This Arduino code, using a LiquidCrystal display, monitors input voltage and power. The circuit connects the LCD and a 10K resistor to specific Arduino pins. Key parameters:

  • Voltage Configuration:

    • input_voltage
    • r1 and r2 (resistor values)
  • Current Configuration:

    • input_current

Functions

  • update_input_voltage(): Reads and updates input voltage.
  • update_input_current(): Placeholder for updating input current.

Main Loop

  1. Voltage Display:

    • Reads and displays input voltage.
    • 2-second delay.
  2. Current Display:

    • Placeholder.
    • Displays current.
    • 2-second delay.
  3. Power Display:

    • Calculates power.
    • Displays power.
    • 3-second delay.

The loop continuously monitors and displays voltage, current, and power on the LCD. Note: Current display functionality is a placeholder.
