Hi,
Im looking for a circuit or information regarding a simple inductive touch system. To put it simply, i have a block of aluminium (its quite large), and i would like to have a system in place, where the user touches the aluminium and this turns on an LED.
These are my questions:
Is "inductive touch" the correct word?
Is this possible with aluminium or does it have to be a material like steel?
How does it actually work? Is it based around picking up your bodies voltage?
Can you point me in the direction of a simple circuit for this if possible (if not, dont worry)
Thanks!
