❤️ 3-Level Water Level Indicator with Buzzer | BC547 Transistor Project 💧⏰

This project is a 3-Level Water Indicator with Buzzer, made using BC547 transistors, LEDs, resistors, and a few basic components. It helps you monitor the water level in your tank and gives an alarm when the tank is full. 🤯

💧 How It Works:
Each transistor detects water at different levels — Low, Medium, and Full.
When water touches the corresponding probe, the LED lights up.
At the top level, the buzzer activates and alerts you that the tank is full. ⏰

⚙️ Components Used:
⚙️ BC547 Transistors
⚙️ 3 LEDs — Red, Yellow & Green
⚙️ Resistors
⚙️ Buzzer
⚙️ Battery / Power Supply
⚙️ Connecting Wires & Water Level Probes

✅ Simple, low-cost and easy-to-build circuit. Perfect for learning basic transistor switching and water-level indication.
