Hello,

What are the logic gates used for in this circuit ?

The aim is to control a motor by using an amplified PWM signal.

What are the entrances W3 and W4 used for ? the LM7805 is a voltage regulator but why is it in this schematic ?

Thank you for your reply

I don't think W3 and W4 are "entrances", it looks like they are just the +12v source and ground connections in the schematic. The LM7805 is there because U1 and U3 require +5v.

Thank you.

But there is still one question:

What are the logic gates used for ?
