Utilizing functions of Sim800l module beyond calls and sms using any Atmega32u4/Atmega328p board and Nokia 5110 (PCD8544) display

Features:

• Request a text file from a URL and display the result on screen (support both Http and Https)
• Show network operator info (name, signal strength, network date & network time)
• Show your approximate location a.k.a LBS information (date, time, latitude, and longitude). Please note that the date and time are based on GMT time
• Save (to eeprom) and retrive last saved location info (date, time, latitude, and longitude)
• Upload your location info to a JSON server (jsonbin.io) including:
  • Google Maps link of your location
  • GMT date and time of the upload entry
• Scheduled location uploads (every 6 hours by default)
• Show weather info of your current location (using OpenWeatherMap API & LBS) including:
  • Current temperature + Min & Max temp (in Celsius)
  • Humitiy level (in percentage)
  • Wind speed (in Meters per Second)
• Serial debugging a.k.a. SerialPassthrough (Atmega32u4 version only)
• Autosleep when idle after a specific time period (30 senconds by default)
• Advanced sleep & wake up functions to minimize power consumption during sleep
• Simple menu to navigate (Nokia Style)
• Optimized SRAM usage (more than 50% is available for local variables)
• Backlight control

Future features:

• FM radio tuner?

Two external libraries are required: "Adafruit_GFX" and "Adafruit_PCD8544"

Needed hardware:

• Arduino Leonardo/Micro/Pro Micro compatible board (Atmega32u4) or Arduino Pro Mini (Atmega328p)
• Sim800l GSM breakout board (5v tolerant)
• Sim card with data plan
• Nokia 3310/5110 LCD (PCD8544)
• Solderless breadboard
• 3 Push buttons
• Jump wires
• Optional: NPN transistor and a resistor to control GND pin of the Sim800l module (to save power)
