I am a newbie...
Hi..
I wanted to post a new thread but cannot cos I'm new here, so hope you don't mind i post here?
I am using this L293 H-bridge to drive my DCmotor. From the attachment, lets say my circuit is similar to that, the left motor. The ENABLE pin 1 is on, and i've PWM of 30% on, 70% off, into pin 2. The inverted 30% off, 70% on into pin 7. The 2nd attachment shows my outputs (are they wrong? should they be mirror image?).
But I do not understand how this works. The DC motor only rotates when either 1-0 or 0-1 at the 2 outputs? And whether its 1-0 or 0-1 determines its direction of rotation?
If the 2 waveforms are mirror images, then the motor rotates in direction A for 30%, then rotates in opposite direction for 70%, and so on?
