If you're new to fishing, don't be discouraged. Even people that have fished a long time have bad days. It sounds like you're on the right track. By using a slip bobber you can present your baits live or artificial in different ways at different depths. It is a possibility that the area you were fishing was not holding fish today. That could change overnight with a weather change or a water level change.
You can sometimes read your water, even fishing from the bank. Take note of the change in water color. Deeper water will be darker and may indicate a drop off which would be likely to hold fish. Also look at the shore where you are fishing. If you see a culvert, ditch, or where water has run into the lake, imagine that same line extends out into the lake. This can be a spot to fish, as well as any standing cover you can see above the water surface.
Don't give up and good luck.
