Summary of MICROCONTROLLER CONTROLLED METAL DETECTOR PROJECTS
The article discusses various microcontroller-based metal detector projects, focusing primarily on the PIC18F252 and ATmega series controllers. It highlights display results using dual scales for material detection, emphasizing the need for specific hardware modifications, such as shorting resistor R21 for certain firmware versions. Different versions cater to discrimination between metals and sensitivity improvements through techniques like oversampling with internal ADCs. Projects include PIC16F873A, ATmega32, and ATmega8-based designs, some using LED displays instead of LCDs for simplicity. Source files and multiple download links are provided for these microcontroller-controlled metal detector projects.
Parts used in the Microcontroller Controlled Metal Detector Projects:
- PIC18F252 microcontroller
- PIC16F873(A) microcontroller (not compatible for all versions)
- ATmega32 microcontroller
- ATmega8 microcontroller
- Resistor R21 (to be shorted in old versions)
- Pulse detection coils (korzinochnymi reels)
- LCD display (varies by version)
- LED display (for ATMEGA8-16PI version)
- Internal RC generator (for ATmega8 versions)

Result of displays in the form of two scales, which are estimated to judge the material goal.In addition, the screen is small scale level of response and the current supply voltage. PIC18F252 The program is intended for controller PIC18F252.The controller PIC16F873 (A) to this version can not be used. This is more demanding to resources controller. 252nd compatible controller on “pins” with 873 – m and can be programmed by the same programmer. The program workable only with korzinochnymi reels! R21 For this firmware needed zakorotit resistor R21 (in the old version of the scheme). In this version the appointment of buttons changed to read
PIC16F873A METAL DETECTOR CLONE PI
ATMEGA32 METAL DETECTOR CLONEPI-2
ClonePI-2 is a further development of the project ClonePI). The main objectives in the design – to get discrimination metals
ATMEGA8 METAL DETECTOR CLONEPI AVR
ClonePI AVR is a so new simplistic solution pulse metal ClonePI)
# Use ATmega8 controller available from Atmel.
# Instead of using an external ADC ADC internal controller.
To get the same sensitivity as to the external ADC, is used oversampling.
# Use taktirovanie of internal RC-generator controller.
ATMEGA8-16PI METAL DETECTOR CLONEPI-W
Instead of LCD used LED display. Cut down on administration, leaving only the most necessary. Take into account some errors in previous versions.
