Dear all,
I already made the schematic here based on .GIF but the simulation's run confusing me
1. According to GIF picture it should lights the LEDs from U4 to U6
but in my schematic and simulation it runs from U6 to U4
2. It should give a linear response to every celcius from the LM35DZ; one LED lights per celcius,
but in my simulation it has not
3. The U4 bargraph LED won't light up / turn on
Would you mind to check it/simulate it in case i did something wrong in my Proteus?
hi,
It runs in Oshonsoft, but the display does not change correctly as the adc inputs are varied. Look at the avi file in the zip.
I suspect the program, do you have the asm file for this circuit diagram.?
i made my design at post #1 into PCB circuit.
but the LM35 is going too heat up itself?
i wonder why
can someone help?
is it related to my potentiometer?
yes, i checked my pcb circuit and there was the mistake swapping the vcc and gnd.
because i ordered my pcb from a pcb layouter person, it seemed to hide at first sight.
the problem is corrected now.
