This project involves a simple schematic that includes an Arduino Nano and a voltage sensor module based on the ZMPT101B. Let's break down the components and their roles:

Components

ZMPT101B Voltage Sensor Module:
- Pins:
  - GND: Ground connection.
  - OUT: The analog output voltage that represents the AC voltage being measured.
  - VCC: Power supply for the sensor module.
  - ACN/ACL: Used for measuring the AC voltage input. These are the terminals where you connect the AC voltage to be monitored.
[Arduino Nano](Arduino Nano):
- Digital and Analog I/O Pins:
  - The Arduino Nano has digital pins $D0$ to $D13$ and analog pins $A0$ to $A7$, which can be used for various purposes such as reading the sensor output or controlling other components.
- Power Pins:
  - $3V3$, $+5V$, VIN: Various power supply pins for different external power requirements.
  - COM/GND: Ground connection pins.
P3:
- A terminal or connector with a single pin named in this schematic, probably for a test point or another simple connection not yet defined.

Connections and Functionality:

Voltage Sensor (ZMPT101B):
- The ZMPT101B is typically connected to an AC voltage source. It outputs an analog signal corresponding to the sensed AC voltage.
Arduino Nano:
- Likely used to read the analog output from the voltage sensor on one of its analog pins (e.g., $A0$). The Arduino can process this signal, converting it into a readable voltage level, which can be used for display, logging, or transmitting to another system.

Current State of the Project:

The components are listed, but no specific connections between the ZMPT101B, [Arduino Nano](Arduino Nano), and the connector terminal P3 are defined yet.
There are existing nets, but not all components are connected to them in the project.

Potential Next Steps:

Connect the ZMPT101B to the Arduino Nano:
- You would typically connect the VCC of the ZMPT101B to the $+5V$ of the Arduino Nano.
- Connect the GND of the ZMPT101B to the COM/GND of the Arduino.
- Connect the OUT of the ZMPT101B to one of the analog input pins of the Arduino (such as $A0$).
Define the purpose of P3:
- Clarify what the single-pin terminal P3 is used for, potentially as an additional input or output point.

Is there anything specific in the project you would like more details about, or any assistance needed in setting it up?
