any circuit diagram that have the application of an ADC0804 please...
any counter like:
*speed counter
*temperature counter
*an digital voltmeter
or anything please..i need any of those....
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
let me know if you need help
PUSH the Helped button if I was helpful
No points will be deducted
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.
