Pin Configuration

2 x AAA Battery Holder with Cover and On/Off Switch Documentation
Overview
The 2 x AAA Battery Holder with Cover and On/Off Switch is a compact module designed to provide a convenient and efficient way to power IoT projects. This module features a battery holder that can accommodate two AAA batteries, a protective cover, and an integrated On/Off switch. The module has four pins that provide a straightforward way to connect the battery pack to your IoT device.
Pinout Description
The 2 x AAA Battery Holder with Cover and On/Off Switch has four pins, each with a specific function. Below is a detailed description of each pin:
Pin 1: VCC (Positive Voltage Output)
Pin 1 is the positive voltage output pin, which provides the power output from the battery pack.
When the On/Off switch is turned ON, this pin will output the voltage level of the batteries (typically 3V or 4.5V depending on the battery type).
Connect this pin to the positive power input of your IoT device.
Pin 2: GND (Ground)
Pin 2 is the ground pin, which provides a common ground reference for your IoT device.
Connect this pin to the ground pin of your IoT device.
Pin 3: SW (Switch Input)
Pin 3 is the switch input pin, which is connected to the On/Off switch.
When the switch is turned ON, this pin will be connected to Pin 1 (VCC), allowing the battery power to flow to your IoT device.
When the switch is turned OFF, this pin will be disconnected from Pin 1 (VCC), cutting off the power supply to your IoT device.
Pin 4: No Connection
Pin 4 is not connected to any internal component and should be left unconnected.
Connection Structure
To connect the 2 x AAA Battery Holder with Cover and On/Off Switch to your IoT device, follow this structure:
1. VCC (Pin 1): Connect to the positive power input of your IoT device.
2. GND (Pin 2): Connect to the ground pin of your IoT device.
3. SW (Pin 3): Leave unconnected, as it is only used to control the internal switch.
4. No Connection (Pin 4): Leave unconnected, as it is not used.

Code Examples

2 x AAA Battery Holder with Cover and On/Off Switch

Overview

The 2 x AAA Battery Holder with Cover and On/Off Switch is a convenient and compact component designed to hold two AAA batteries and provide a simple on/off switching mechanism. This component is ideal for IoT projects that require a reliable and easy-to-use power supply.

Features

Holds two AAA batteries
 Includes an on/off switch for easy power control
 Cover protects batteries from accidental contact or exposure
 Compact design for easy integration into IoT projects

Pinout

The 2 x AAA Battery Holder with Cover and On/Off Switch does not have any pins. The power output is provided through two terminals, marked as `VCC` and `GND`, which can be connected to the positive and negative terminals of a microcontroller or other electronic components.

Examples

### Example 1: Using with Arduino Uno

In this example, we will connect the 2 x AAA Battery Holder with Cover and On/Off Switch to an Arduino Uno board and use it to power an LED.

Hardware Requirements

2 x AAA Battery Holder with Cover and On/Off Switch
 Arduino Uno board
 LED
 Resistor (220)
 Breadboard and jumper wires

Code
```c
const int ledPin = 13;  // LED connected to digital pin 13

void setup() {
  pinMode(ledPin, OUTPUT);
}

void loop() {
  if (digitalRead(SWITCH_PIN) == HIGH) {  // Read the switch state
    digitalWrite(ledPin, HIGH);  // Turn on the LED
  } else {
    digitalWrite(ledPin, LOW);  // Turn off the LED
  }
  delay(50);
}
```
Notes

`SWITCH_PIN` is not a physical pin on the battery holder, but rather a digital pin on the Arduino Uno board that is connected to the on/off switch.
 The `digitalRead()` function reads the state of the switch, and the `digitalWrite()` function sets the state of the LED.

### Example 2: Using with ESP32 DevKitC

In this example, we will connect the 2 x AAA Battery Holder with Cover and On/Off Switch to an ESP32 DevKitC board and use it to power a simple Wi-Fi enabled device.

Hardware Requirements

2 x AAA Battery Holder with Cover and On/Off Switch
 ESP32 DevKitC board
 Breadboard and jumper wires

Code
```c
#include <WiFi.h>

const char ssid = "your_wifi_ssid";
const char password = "your_wifi_password";

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }

Serial.println("Connected to WiFi");
  Serial.println("Starting device...");
}

void loop() {
  if (digitalRead(GPIO_NUM_0) == HIGH) {  // Read the switch state
    Serial.println("Switch is ON");
  } else {
    Serial.println("Switch is OFF");
  }
  delay(500);
}
```
Notes

`GPIO_NUM_0` is a digital pin on the ESP32 DevKitC board that is connected to the on/off switch.
 The `digitalRead()` function reads the state of the switch, and the `Serial.println()` function prints messages to the serial console.

By using the 2 x AAA Battery Holder with Cover and On/Off Switch, you can easily power your IoT projects and add a convenient on/off switching mechanism.
