Watch a capacitor charge, discharge, and stabilize in real time — CAP-VIEW turns theory into live visuals with LCD and RGB feedback.

Welcome to Candade LabWorks
This channel brings hands-on electronics and IoT projects to life — from circuit fundamentals to embedded systems and beyond.

🔋 About This Project
CAP-VIEW is a real-time capacitor monitoring system that visualizes charging, discharging, and stable states using an LCD display and RGB LED feedback. With interactive visual cues and transistor-based discharge control, this project makes RC circuit theory come alive.

🧰 Components Used
Arduino Uno / Nano
Capacitor (e.g., 1000µF)
BC548 Transistor
RGB LED (Common Anode)
16x2 LCD Display
Resistors (1kΩ base, 47kΩ charging, optional for LED)
Breadboard + Jumper Wires

⚙️ Pin Connections
Capacitor Voltage → A0
BC548 (Discharge Control) → D2
RGB LED → D5 (Red), D6 (Blue), D9 (Green)
LCD → RS: 4, EN: 7, D4–D7: 8, 10, 11, 12

🎛️ Control Logic
🔴 Discharging: Voltage above 4.7V → Red LED + LCD message
🟢 Charging: Voltage below 1.0V → Green LED + LCD message
🔵 Stable: Between thresholds → Blue LED + LCD message
Continuous monitoring with automatic transistor-based discharge

⚡ How Capacitor Charging & Discharging Works
A capacitor stores energy in the form of an electric field when connected to a power source.
During charging: Voltage across the capacitor gradually rises as it fills with charge, following an exponential curve. In this project, the LCD shows “Charging” while the LED glows green.
During discharging: The stored energy is released back into the circuit, causing the voltage to drop exponentially. Here, the transistor helps discharge, the LCD shows “Discharging,” and the LED glows red.
Stable state: When voltage sits between thresholds, the system marks it as stable, shown on LCD and with a blue LED.
