   Objective:          
      Our proposal involves utilizing a cellular phone to establish a connection
      with the Bluetooth Module of ESP32 and subsequently regulate the LED functionality. 
      Specifically, we aim to control the LED situated on the Heltec WiFi 32 board, 
      which is directly linked to PIN25/GPIO25.

      Link: https://medium.com/jungletronics/pir-motion-sensing-led-display-6192f403c7db
   
   Objective:          
      This implementation relying on interrupts offers distinct advantages over the previous code(#37), 
      especially in scenarios involving time-sensitive events, such as motion detection. 
      Interrupts empower the microcontroller to swiftly react to changes in the sensor state without 
      the necessity for continuous monitoring within the primary program loop, 
      distinguishing it from conventional polling techniques (#37).

      Link: https://medium.com/jungletronics/pir-motion-sensing-led-display-6192f403c7db
   
   Objective:           
      This first code utilizes a polling approach, where the detection of motion relies on repeatedly checking 
      the sensor state within a loop and waiting for changes. This code employs a PIR sensor to identify motion 
      and adjusts an LED accordingly. Messages indicating the initiation and cessation of motion are printed to 
      the serial monitor. The pirState variable is employed to track the motion detection state, 
      preventing the generation of redundant messages.

   Objective:    
      This code is incredibly straightforward and uncomplicated.
      It will initiate a WiFi connection (test1) and transition the ESP8266 into Deep Sleep Mode (test2).
      Perform a reset (GND on pin RST) to restore its functionality.
      It is designed for an ESP8266 microcontroller using the Arduino framework. 
      It demonstrates low-power modes, specifically Deep Sleep mode,

   Objective:       
      This section delves into the typical implementation of low-power modes on the ESP8266. 
      Below is an official example from Espressif showcasing how the deep sleep mode can be 
      employed to conserve power. It's important to note that the ESP8266 doesn't offer advanced 
      low-power modes seen in some other microcontrollers. 
      Nevertheless, you can employ specific strategies to effectively reduce power consumption.
