Hello Papabear7, welcome to the Forum!
Lots of folks join after a long photo-hiatus, many with a 35mm film background. The controls have changed somewhat but the basics are the same;
You control the exposure with aperture, shutter speed and ISO. Everything else is details, and digital offers more technology, more ways to modify the result (or, some say, ruin it), but a correctly-exposed capture is always the best start.
Here's a refresher on the primary camera controls
Getting Started With Photography | Beyond Megapixels Click on " Going Manual; Learning Exposure Basics".
Remember, now aperture and shutter are controlled with the front and rear thumb dials, and ISO is usually selectable on one dial with an additional 'push' on the ISO button. Again, pretty simple, once it's learned.
Take lots of photos, download a free online processing app and learn to use it. Post some photos soon, too!
