How to Program an Arduino Based Metal Detector
Hi Jorbi,could you please explain why counting the pulses for determination of frequency is not a problem (see 2.) But counting pulses to determine the degree of dampening is a problem (see 1.)?As you mentioned, the execution of the interrupt code takes about 5us and hence we might miss the next pulse. Why is it only valid for mehtod 1.)Thanks in advance!!brandit

Thanks mate, I appreciate that
I added two pictures in the 'electronics assembly' step. If you want a picture from the bottom I can share it as well, but it is a mess :D I made many reworks to optimize and hence desolder / solder many things.
Sure! I will add it to the article today evening when I get home to my laptop. Make sure to check out the placement of the 4 spikes on which the board sits. It is designed for the mounting holes of the board I used. Maybe you have to adapt it a little.
