The aim of the project is to construct a metal detector. The system is capable of alerting through buzzer in case of metals in its presence. The main controlling device of the project is Arduino. Metal sensor, buzzer is interfaced to the Arduino microcontroller. When the metal sensor detects the metal, this data process to the Arduino then Arduino will activate the buzzer for alerts. To achieve this task microcontroller loaded program written in embedded C language.  

The features of the project are:

1. Construction of metal detector.
2. Alerts through buzzer.

 

The major building blocks of this system are:

1. Power Supply.
2. Arduino
3. Buzzer with driver.
4. Metal sensor.
