Hello again,
Nowadays, I am designing a stepper motor controler for usunig with arduino. I have a L293D H-Bridge and a 4wire stepper motor. Datasheet is here
I want to use arduino for PWM and I found some projects on internet such as:
https://raawbot.wordpress.com/2009/10/28/motor-control-with-arduino-and-l293/
But in this example project they used the same ground for both logic input and motor supply. I checked the datasheet by myself but it was quite complicated to decide....
Does anyone has an idea which ground pin is for logic and which is for motor suply?
Regards,
Özgür
