Metal Detector Arduino Project
This project involves creating a simple metal detector using an Arduino.
The system works by charging and discharging a capacitor and measuring the change in capacitance.
The presence of a metal object changes the capacitance, which is detected and displayed via the Serial Monitor.
Components Needed
- Arduino Board
- KY-036 Metal Touch Sensor Module
- Jumper Wires
- Breadboard (optional)
Block Diagram
Hardware Wiring Explanation:
Software (Arduino IDE):
Open the Arduino IDE on your computer.
Write or paste the provided program into the IDE.
Select the correct board and port in the Arduino IDE under the Tools menu.
Upload the program to the Arduino.
Project Operation
The KY-036 detects a touch (or presence) through the metal plate, outputting a HIGH signal when touched.
The Arduino reads this signal and can trigger actions, like turning on an LED.
Open the Serial Monitor (set to 9600 baud) to see "Touched!" when you press the sensor. The onboard LED will light up upon touch.
