Board 3: Smart Bridge Control and Emergency Communication

Board 3 is responsible for the control of the smart bridge in case of flooding, it also manages emergency communication (call & SMS) in response to fire & flood incidents.

Connections

• Servo Motors for Bridge Control:

  • Servo 1: Connected to pin servoPin (5).
  • Servo 2: Connected to pin servoPin2 (6).

• Fire Signal In (from Board 2 - Fire Sigal Out): Connected to pin fireInPin (10).

• Flood Signal In (from Board 2 - Flood Signal Out): Connected to pin in (9).

• Emergency Communication:

  • SIM900 TX: Connected to pin 7.
  • SIM900 RX: Connected to pin 8.
  • Buzzer (for emergency alarm): Connected to pin alarmBuzzerPin (11).

• NB: all negative (-ve/GND) wires are connected to GND.

For detailed connections, refer to the Circuit Diagram.

Smart Bridge Control

• The servos control the bridge's position.
  • Bridge Up Position: BRIDGE_UP_POSITION (70).
  • Bridge Down Position: BRIDGE_DOWN_POSITION (0).

Fire and Water Emergency Communication

• Fire Detection:
  • Fire Signal In: Connected to pin fireInPin (10).
  • Automatic emergency call and SMS alert are triggered in case of fire.
• Water Level Detection:
  • Flood Signal In: Connected to pin waterInPin (9).
  • Automatic emergency call and SMS alert are triggered in case of rising water levels.

Usage

1. Adjust configurations in the code if necessary.
2. Upload the Board3_SmartBridge_SMS.ino code to your Arduino board.
3. Connect the components as specified in the connections section.
4. Power on the system and test the smart bridge control and emergency communication systems.

Refer to the code file for detailed comments and configuration instructions.
