Re: Mod proposal to PHSNA
One: Why use analogue pin unless you wish to measure it? Why not a digital pin that is pulled high with a resistive divider. Also solves problem of noise in ADC conversions.
Two: The limit of a USB port is 500mA. Some ports (laptops)
cannot even manage that. Don't forget that for 100mA of 12v DC it
will take nearly 300mA of 5v.
