Sensitive Pulse Induction (PI) metal detector which is based on ARM STM32 microcontroller, which has significantly better features than Arduino and is also cheaper. It can detect metal coih at distance of 30cm, and big metal object at distance of more than 80 cm. The indication is made on a WS2812B module of eight LEDs and a buzzer.
The sensitivity of the metal detector is adjusted manually by rotating the encoder knob. There is also a menu mode. The first press on the encoder knob enters the LED brightness adjustment mode. Second press, buzzer on/off mode. Second press, buzzer on/off mode. The fourth press, we enter the adjustment mode for large or small objects. The fifth press, exit the menu mode and auto-adjust the sensitivity.

A simple and effective project, nice work. Have you measured the inductance of the 20cm/25turns coil? What is the mean steady state pulse width and which its repetition rate? and the comsuption?
❤ very yusful. 👍 Nice video yt. ❤
Very interesting! Would you mind sharing the approximate cost you spent on the parts, but without material cost of the case ?
interesting, useful!
I have an error when copy your codes. Arduino didn't accept WS2812 led library. Can you share with yours ? Alsa Arduino IDE does not support with TIMER_CH1 and the others. How can I fix that?
I am having the same issue, did you solve it?
Please make a longrange locator sir❤
nice project..what material you use for the box?what is the name?
PVC board 3mm and 5mm
Hi, I'm working on this project. Do all 10 files get loaded onto STM32?
Bonjour, petit commentaire, peut-être aurait-il mieux valu mettre les diodes de contrôle sur la face supérieure du boitier ?
True, I placed them sideways for better visibility of the video
And the 20k & 100k presets, where are they in the schematic?
R7 and R8
Any 15khz metal detector or more then 15 khz i need strong one
would also work with an ESP32 or is the code different?
For ESP32 code is differerent
Hi I want to build my metal detector too but I found some inconsistencies when I looked at your schematic. In the schematic there are a lot more capacitors than you actually have on the board, also the values don't match like for example 3300mF is really a lot for a condenser, also why do you have potentiometers on the board, those are not in the schematic either. Thank you very much and have a nice day.
3300mf is 3300 microF, and more capacitors on schematic for more stability of the device (filter capacitors)
at 5:15,,, what??? 12 and 23 cm ? or is it 20 cm Im confused.
Only 20cm, I use 12+20(two coils in series) only for testing
