    ADC 0804

    you can build a digital thermometer.
    you need lm35 (see data sheet) it has 3 pins vcc, gnd and out which is in V (there is a relation bw V and degree C) the sensor will be the input of adc ( see data sheet for connection)the output od adc can be connected to leads or any
    good luck

    ADC 0804

    from left to right connect on pin 1 4.7k to 9v vcc pin 2 to the in of adc0804 and pin 3 to ground.
    scale factor is 0.1V/degree C
    As for the adc0804 see the picture attached

    sorry I do not have a schematic software to make things quick I used paint/
    connect all outputs to resistor to vcc.
