How can I make my robot drive straight using PID and the HC SR04 ultrasonic sensor?

I have a feeling there is more to your question than your saying.

You can make your robot avoid objects but to make it run a strait line you need to be able to sense the position - with a compass, or an accelerometer or by monitoring the rotation of each wheel. Your SR04 isn't going to help you drive a direct line.

So, how could be the code to make my robot run strait using an encoder?
Using PID, I'm searching things about PID but I until don't found a site that explained me it.

Don't need that to make a robot drive straight. You need that if you want the robot to see objects in front of it so it can either stop or avoid the object.
