Thanks for the feedback. I used google translator to translate your tutorial and it did not come out quite right and I was confused about quite a few things. I figured out that by the oscillator you meant the NE555 output. I checked and I was getting a square wave but with only 2.7KHz instead of 4.8KHz. I was putting caps in parallel to get to 3.9n but I came up short. I am going to replace the capacitor. As far as the potentiometer I was only trying to make sure. Thank you for your help.
I was wondering if i could keep in contact with you through email. I want to give you mine but youtube keeps not posting my previous two comments. I am confused about the analog input signal. Is it supposed to be 4.8 Khz with 5V peak to peak. Also there is an arrow from the LM358 to a 10K which I figure out that it meant potentiometer but then I am confused as to how to connect it. There are three terminals which ones did you connect to which. I am a newbie. Thank you so much for your help.
@wzjz123 Well..i read you don't know how to connect one of the simplest electronic components, the potentiometer..i think you must study what are you going to use (the electronic components), and only after make some circuits. How can you make circuits if you don't know how the components are made and how they work together? And..the 4,8 KHz freq. is the oscillator, not the analog input. The ADC takes about 10 clock cycles, so it can perform 480 conversions/sec, so the max. freq. input is 240 Hz
Yes I have spent days checking my wiring the only part that I am confused at is the Analog input. Did you input a 4.8 Khz with a 5V peak to peak sine wave? Plus what do you mean by checking the oscillator? If possible can you contact me at engjzneer [at] gmail[dot]com . Thank you so much for your help.
Yes I have spent nights checking the wiring the problem is that I am a little confused about the part about the analog input signal. Can you please contact me at the following email address so I can go over my problems with the circuit. Thank you so much for your help. I have spent so much time on this. Thank you.

Hey buddy I designed and built this project using your schematic. I am stuck. I have designed it twice now. When I power it up I get all the LEDS to light up and thats it. When I move the 10K potentiometer nothing happens. I would appreciate your help
I don't mean to sound critical of your circuit, but why are you making such a complex circuit with simple logic? To show it can be done? Why not try to do it with CPLD devices (so that the resulting circuit is smaller and reconfigurable.)

@wzjz123 and the oscillator produces a quare wave, not a sine wave.
Remember: before the practical there's the theory.

@wzjz123 have you checked all the wirings? The oscillator? Check the main signals with a probe and/or an oscilloscope.

making this requires lots of efforts and patience!

I never used CPLD devices. I've only some TTL ICs, so (sometimes) i make digital circuits with TTLs, or i use PICmicro.

@Alu10000
Can you please help me make this 8 bit SAR ADC. I would owe my life to you. Thank you.
