Any help is greatly apreciated

you should better to use a simple 4bit Flash ADC and a pic16f84a as a 8 to 4 priority encoder........wahahahahaha

Why not use a single chip solution like PIC16F88.

Once again, this looks like a homework assignment huh.... Well you say your stuck, how far have you gotten?? Do you have anything in terms of your assignment?? If you show some effort on your part, you will more likely get some help...just a thought...

 

yes it is a lab project but the teacher is not the most helpful so i am looking at orther sources

 

hi,
That link is not a analog to digital convertor, its basically a temperature sensitive bridge, using 3, 10K0 resistors and a thermistor.

You would need to amplify the output of the bridge before the signal was input to a A2D convertor.

Look at the ADC0801 ic series, they will operate as a 'stand alone A2D', also with a differential input to suit the bridge.
