Hi Friends,
I have a doubt.
I would like to make a tack circuit (LC circuit) which can detect a magnetic field.
Its purpose is to make a water meter. When the dial in the meter attached with a magnet rotates my LC circuit has to charge to 3.3V or discharge to 0V.
Then only my microcontroller can count the number of rotations and thus the water consumption.
Can anyone help with this?.
