This is my schematic that i am using to drive a bipolar stepper motor. The thing is i want to know what wrong with it?
Here is the connection:
Q1> Do i need to connect a 10k resistor between the 16F84a and sn754410 pins 2,7,9 and 15 or leave it as it is?
Q2> I am using same power source for Vcc1 and Vcc2 does it matter because the pic need 5V and the stepper need 5V same volt why get a new power source?
Q3> The motor behavior is strange going back and forth, its strange if you spot any mistake in the schematic let me know?
Thanks in advance
