This project implements an SOS call system using Arduino UNO. It is designed to send an emergency distress signal (SOS) to predefined contacts when activated. This can be a crucial safety feature in situations where immediate help is required.

• Arduino board (e.g., Arduino Uno)
  
• GSM module (e.g., SIM900)
  
• GPS module (optional, for location tracking)
  
• Push button or trigger sensor
  
• Power source (battery or power supply)
  
• SIM card with active plan
  
• Required connectors and cables
  

• Connect the GSM module to the Arduino using appropriate pins (TX, RX, VCC, GND).
  
• Connect the GPS module in a similar fashion if used.
  
• Wire the push button to an Arduino pin for activation.
  

• Connect all the components according to the wiring diagram.
  
• Insert a valid SIM card into the GSM module.
  
• Load the provided Arduino sketch onto the board using the Arduino IDE.
  
• Ensure that the GSM and GPS modules are powered up and properly connected.
  
• Upload the code to the Arduino.
  

• Power up the Arduino with the required power source.
  
• Press the push button to trigger the SOS call.
  
• The GSM module will establish a connection and send an SOS message to predefined contacts.
  
• Optionally, if a GPS module is connected, the location coordinates can be included in the SOS message.
