Reed Switch With Arduino

This project demonstrates how to interface a reed switch with an Arduino board to detect the presence of a magnetic field. The system uses an LED to provide visual feedback of the switch state.

Hardware Requirements

Pin Configuration

  • Reed Switch: Connected to Digital Pin 2
  • LED: Built-in LED on Pin 13

Circuit Description

The project uses a reed switch with Arduino’s internal pull-up resistor. If you prefer using an external pull-up resistor:

  1. Disable the internal pull-up by removing INPUT_PULLUP and using just INPUT
  2. Connect a 10kΩ resistor between the reed switch pin and 5V
  3. Connect the reed switch between the digital pin and GND

Circuit Options:

  1. Using internal pull-up (current setup):

    • Reed switch between PIN 2 and GND
    • No external resistor needed
  2. Using external pull-up:

    • 10kΩ resistor between PIN 2 and 5V
    • Reed switch between PIN 2 and GND

Project Codes

How It Works

  1. When no magnet is present:

    • Reed switch remains open
    • Digital pin reads HIGH
    • LED remains OFF
    • Serial monitor shows “Switch opened”
  2. When magnet is nearby:

    • Reed switch closes
    • Digital pin reads LOW
    • LED turns ON
    • Serial monitor shows “Switch closed”

Installation

  1. Connect the reed switch between digital pin 2 and GND
