Dear all,
I built a circuit to detect temperature changes of range 10-40 degrees Celcius based on this schematic in the GIF file attachment below.
I made the schematic and run simulation based on Proteus Iris program, the file is attached below: rangebartan.dsn in a zip file
But it's been showing this problem:
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
Please help me with some review and suggestion and correction
Thanks God bless
