[weird99]

hai every wan..i need some experts help here...... i need to do variable fan controller with temperature sensor.....i am a very beginer for 8051...i have solve some problem and i got sum problems also .......i dun noe how to interface the adc to 8051 ...i must do a circuit wich from non-inverting amplifier to adc and to 8051.i have attach my circuit how i did my non-inverting amplifier,now i dnt noe hw to interface it wit adc and 8051.my adc cip is (adc0804lcn) :roll: View attachment New Microsoft Office Word Document.rarView attachment New Microsoft Office Word Document.rar

Do you mean the uC you work on doesn't have an ADC input pin?

better to use a microcontroller with inbuilt ADC,
use avr(4-12channels 10 bit), or aduc(4channels 12 bit) or any other 8051 derivative
it will save time and space.
