Introduction: A Digital Potentiometer Circuit Without Arduino!!

Hi there! 
Potentiometers basically control a certain parameter, such as brightness, contrast, or volume. However those we usually get in the market use knobs. So how do devices control volume, contrast etc with just 2 buttons?? Well, if you've got the Arduino, its somewhat simple. 
Now for beginners its not so simple.... so here I've designed such a circuit without an arduino. This one uses 3 buttons, but if your not lazy you can modify the circuit for just 2. Easy for beginners, even if the circuits look complicated. It also has a display, which you may not put if you don't  have the required components. See the video for the rest.............




Images of the diagram will help.............
