Arduino Setup

To set up your Arduino for BLE communication, follow these steps:

1. Hardware Requirements:

   • Arduino Uno R4 WiFi
   • DHT22 sensor for temperature and humidity
   • MQ135 sensor for air quality
   • 20x4 I2C LCD for displaying data
   • Breadboard and connecting wires

2. Software Requirements:

   • Arduino IDE
   • Necessary Arduino libraries:
     • ArduinoBLE.h library
     • DHT.h by Adafruit
     • LiquidCrystal_I2C.h for LCD

3. Connections:

   • Connect the DHT22 sensor to the Arduino:
     • VCC to 5V
     • GND to GND
     • Data pin to digital pin 4
   • Connect the MQ135 sensor:
     • VCC to 5V
     • GND to GND
     • Analog output to A0
   • Connect I2C LCD:
     • VCC to 5V
     • GND to GND
     • SDA to A4
     • SCL to A5

Installation

To run this app, you need to have Xcode installed on your Mac. Follow the steps below to set it up:
