Hello Guys, I am trying to do a simple digital electronics project where I put two seven segment displays and once I connect the voltage source, the displays start counting automatically from 00 to 99. Here is a video of exactly what I want to do: My group and I found the attached schematic which we think is what we need to build to make the circuit in the video. We built it, but the displays just show two values which sort of look like "A", and it doesn't change. I was wondering, could someone tell me if that particular schematic does what I want to do? What is the use of the timer? Is that what increments the values from 00 to 99?? What is the use of the potentiometer? To adjust frequency? Thank you all very much!
