Hello,
I'm trying to control a 3v dc motor from msp430 launchpad connect by USB cable with array of darlington transistors circuit known as ULN2003 (data sheet in attachement)
in the picture below, I replaced the motor with red LED to protect the chip while testing. but I can't light it
is 3v not enough to power the ULN2003?
