DIY LED Blinking Circuit Using Basic Components
DIY LED Blinking Circuit Using Basic Components Objective: To build a simple LED blinking circuit using a resistor, diode, capacitor, and transistor to understand their practical use. Components Required: Resistor – 1kΩ (for current limiting) Diode – 1N4007 (for protection) Capacitor – 100µF (for timing) Transistor – BC547 (as a switch) LED – Any color Battery – 9V Breadboard & Wires Circuit Diagram: 🛠️ (You can draw a simple schematic or I can guide you to use online tools like Fritzing to visualize it.) Step-by-Step Instructions: Step 1: Connect the Resistor Place the 1kΩ resistor on the breadboard. Connect one end to the positive (+) terminal of the battery. Step 2: Connect the Diode Place the 1N4007 diode with the cathode (striped end) facing the negative (-) terminal . This protects the circuit from reverse polarity damage. Step 3: Add the Capacitor Connect the positive leg of the capacitor (100µF) to the resistor’s other end . Connect the negative leg to th...
