hello,im new around here and im not limited internet connection. im doing a project named automatic handwash with auto refill. well here is my coding. im using mikroC for the coding.

based on the coding, i manage to get all the washing circuit to work, but my problem is on the refill circuit as i dont know the coding. i know that port A can be used as ADC but i dont know how to use it. my liquid level sensor circuit work properly but i need the coding on PIC. i want to make when port A2 and A3 read 0V,it will turn on port D2 and D3.. can anyone help me?? im really noob in this:-(

please and thank you

hello,

my liquid level sensor circuit work properly

so,is it an analog level sensor.?
if yes, what kind of signal is delivered by this ?
it must be in the range 0 to 5 V for all of the measuring range..

i want to make when port A2 and A3 read 0V

do you have 2 analog sensors ?
or 2 dry contact ?

Explain clearly to get support...

Maybe with a drawing with sensor location ..water circulation..

yes the output is 5V..but i need it to be 0V which means the PIC read it as logic 0. it is the same circuit actually. but i make it 2. i will attach my circuit. im sorry mate.
