but if an led shorts, won't the usb port turn off automatically?
can i build in a safety thing somehow? maybe a zener?
putting the amperemeter between red and black one, the usb port immediately shut down and mac os said it was drawing too much power
It *should* be OK in theory to just connect them the way you say
that have the following specs:forward voltage typ. 1,25 V
is usb such an unconstant power source?
if it gives me less than 5v, its okay, nothing is damaged
should i think about putting a 3-4 ohm resistor in series,
giving each LED only about 1,2 V instead of 1,25 V to be on a safer side?
is it working fine like this?
