i need to make a teaching aid for my graduation task

one of the teaching aid i have to make is temperature sensor using LM 35 and ADC using adc0808

i already have make the LM 35, even i still can't measure the output current from LM 35, but since my deadline is close, then i only use a potensio to adjust the current level from output LM 35 to non inverting input of my OpAmp

i also use another potensio as Rf of my OpAmp, to adjust, the amplifying of My system.

then i meet the problem in using ADC 0808.
i have the data sheet but, still i didn't know how to start using it.

i haven't touch the coding area, still working on the hardware

I know that Vin for ADC 0808 formulation but, i can't find any appropriate text which emphasize on it

if any body know about some text which explain a little further about ADC 0808 please email me at Thanksgave@mail.com
