Flashing led using 101f hall effect sensor and magnet

Описание: 🧲 Flashing LED with 101F Hall Effect Sensor & Magnet 💡
In this simple DIY electronics project, we use a 101F Hall Effect Sensor, a magnet, and a few basic components to create a magnet-activated flashing LED. This is a fun and educational project perfect for understanding magnetic sensors and switching circuits.

⚙️ How It Works:

The 101F Hall Effect Sensor detects the magnetic field when a magnet comes close.

It switches the output from HIGH to LOW (or vice versa), depending on the magnet's position.

This change triggers a circuit to flash an LED, using a basic transistor-based or logic switching design.

Once the magnet is removed, the LED stops flashing (or continues, depending on design).

🔋 Components Used:

• 101F Hall Effect Sensor
• NPN Transistor (e.g., S8050, 2N2222, BC547)
• LED (any color)
• Resistor (220Ω–1kΩ for LED)
• Pull-up resistor (10kΩ for sensor output)
• Capacitor (optional, for smooth flashing)
• Magnet (neodymium or similar)
• Power Supply (3V–5V or 9V with regulator)

💡 Key Features:

• No Arduino or microcontroller needed
• Magnetic proximity detection
• Flashing LED effect when a magnet is near
• Can be used in interactive toys, counters, or door sensors
• Easy to modify and scale

📦 Applications:

• Magnetic switch circuits
• Bike speed detection (with rotating magnets)
• Door open/close indicator
• DIY magnetic-based toys or gadgets
