Good Evening, i need assistance with a hobbyist project of mine:
I need to make a device that is relatively small and detects a magnetic field/ polarity: and once detected it then makes a vibration, and if at all further possible 1 vibration would signify 1 pole and 2 vibrations would signify the other pole.thus meaning that holding the device over a magnet would signify its position and which way up it is. Where do i start going about making this device? i.e. components to use circuits etc. Should i use PIC to programme a chip to do this for me? The only thing i have found throughout my research is a hall sensor for the magnetic field detection. Many Thanks in advance
