What's the input-resistance of any analog/digital pin - so, any chance of blowing the 328p by connecting inputs directly to a voltage source?
IILInput LeakageCurrent I/O PinVCC = 5.5V, pin low(absolute value)1 ?AIIHInput LeakageCurrent I/O PinVCC = 5.5V, pin high(absolute value)1 ?A
Sounds risky; but thanks for the reply :-)
I measured the input resistance of an analog pin with a normal multimeter,
The risk in inversely proportional to your knowledge of electronics and the AVR microprocessor chip.
You should never use a multimeter to measure resistance if power is applied to a circuit.
So if I get a very high resistance-value, shouldn't there be a pretty good chance that the input-resistance really is high?
