One of my favorite electronics projects are metal detectors. I'm trying to build some famous and more complex detectors like the TGSL (VLF) and the Delta Pulse (PI) but I also decided to try a very simple approach - using an Arduino and a few electronic components. As I also work with programming, it was very interesting to join the 2 areas (electronics and IT). The detector works as an "educational" purpose as it detects a large coin at about a 3-4 centimeters distance from the coil while professional detectors can detect objects at a very larger distance, although it can be a great opportunity to learn more about how metal detectors work (in this case using the Pulse Induction technology). I found this project in a YouTube video, and it is not created by me but I'm sharing it with you. In my test, I replaced the LED with a piezo buzzer, so, the components I used were: - 1x Arduino UNO - 1x protoboard (optional as you can mount the components any other way) - 2x 220...
DYI and homemade lover. Making things by ourselves gives us pleasure and it can be useful for so many everyday life tasks.
