Hey guys
I want to use a ULN2003A chip to drive DC motors for a tank
my question is, can I use the ULN2003A to reverse the current?
meaning, passing both + and - through the chip, let's say {1..7} ; 1 = + ; 2 = - ; 3 = - ; 4 = + and use 1 and two for one direction and 3 and 4 for other direction.
I don't know if it only passes + through the chip or if also passes -, meaning I can use it to reverse the direction.
my question is, can I use the ULN2003A to reverse the current?
No.
For that you need a H-Bridge circuit.
Thank you
