Hi all, I just couldn't find the answer on web so I had to ask you guys.
Based on my understanding, input power is ideally equal to the output power of a circuit unless it is dissipated to heat.
So I was looking at the ULN2003 Darlington controlling a 28byj-48 stepper motor using an Arduino Uno (I know it is NOT recommended due to high current risk).
I couldn't find any measurements of I\O current\voltage of the chip and my question is -
Is there a power amplification produced in order to drive the stepper, or maybe voltage is dropped and current increased?
