Hello Electrical engineering community.
I am using motor drivers to get 5v to 12v and I am controlling each motor with each IC L293D.
Each motor driver is controlling each motor and the outputs is taken from only one side of the IC.
12v battery -> 7805 voltage regulators -> two L293D IC's with 12v given and the output is taken via diodes to resist back emf-> 100 rpm 12v DC motors.(the other two output pins of the IC are left floating).
Everything is working fine but from 1st pin I am getting an output of 10.23 and 0.72.. and from the second IC I am getting an output of 9.1 and 0.61.
I don't understand why is there a difference of 1v.
Sorry I can't upload a picture of the ckt or make the question in more detailed manner as I am using my phone.
Any help would be appreciated.
