It includes **LED alerts** to indicate warnings.\n\n## 📸 Circuit Diagram  \nHere’s the circuit setup for this project:  \n\n![Circuit Diagram](circuit_img.png)\n\n## 🔧 Features  \n✅ **Real-time status display** using `Adafruit_LiquidCrystal`  \n✅ **Signal detection** using a digital sensor  \n✅ **Alert system** with LED blinking  \n✅ **Automatic LCD updates**  \n\n## 🛠 Components Used  \n- **Arduino Board** (Uno/Nano)  \n- **Adafruit LCD Display**  \n- **LED** (for alert system)  \n- **Resistors \u0026 jumper wires**  \n- **PIR sensor**  \n\n## 🚀 How It Works  \n1. **Connect the Circuit**: Follow the diagram above.  \n2. **Upload the Code**: Load `lcd_alert.ino` to your Arduino.  \n3. **Power On**:  \n   - If a signal is detected, the LCD displays **\"Unidentified\"**, and the LED blinks.  \n   - If no signal is detected, the LCD displays **\"All Fine\"**, and the LED turns off.  \n\n## 📜 Code  \n```cpp\n#include \u003cAdafruit_LiquidCrystal.h\u003e\n\nAdafruit_LiquidCrystal lcd(0);\n\nint signal;\n\nvoid setup() {\n  pinMode(2, OUTPUT);\n  pinMode(3, INPUT);\n  pinMode(4, OUTPUT);\n  pinMode(6, OUTPUT);\n  lcd.begin(16,2);\n}\n\nvoid loop() {\n  signal = digitalRead(3);\n  if (signal == 1) {\n    digitalWrite(6, LOW);\n    digitalWrite(2, HIGH);\n    lcd.setCursor(2,0);\n    lcd.print(\"Unidentified\");\n    for (int i = 0; i \u003c 10; i++) {\n      digitalWrite(4, HIGH);\n      delay(100);\n      digitalWrite(4, LOW);\n      delay(100);\n    }\n  } else {\n    digitalWrite(2, LOW);\n    digitalWrite(4, LOW);\n    digitalWrite(6, HIGH);\n    lcd.clear();\n    lcd.setCursor(2,0);\n    lcd.print(\"All Fine\");\n  }\n}\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmatesoft2033%2Fsignal-detection-lcd","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmatesoft2033%2Fsignal-detection-lcd","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmatesoft2033%2Fsignal-detection-lcd/lists"}
