please help me! urgent :( Night Lamp with morning Alarm Circuit

[uen28]

this circuit is our project in control system.
unfortunately, when i tried to simulate this on multisim, it won't work properly.
what has gone wrong?
i don't know what to do..
time is running out.
we need this badly T_T
thanks po.

Could you post your simulation schematics.
UM66 is a melody IC and I doubt it is one of the simulation parts model.

[uen28]

we replaced um66 by a tone generator using 555.
pero yung LED po di mabuhay at mamatay accdg to what is expected.
yung LDR, we replaced it muna by resistors, we vary nalang ang value.

[uen28]

pano ko po pala isend yung simulation?

@TS

comparator at flip-flop nalang gamitin nyo, settable pa....

We cannot "guess" what happened and cannot help you with it if without your simulation details/schematics.

Screen capture will do (PrintScreen and paste in Windows Paint).

konti lang naman mga parts, pwede ng ibread board yan.

I am wondering -
if you have no more time (urgent)
if the circuit has been proven to work as shown in an article in a reputable magazine
if you are equipped with explanation on how it works

why waste time and simulate? I suggest be practical. Just build the circuit.

mahirap yang mga simulator nayan, iba parin pag actual, may bug kc minsan mga simulator

@revsphere

for a simple circuit like that
it should be ok to simulate.
I designed more complicated circuits
and the results are really close sa actual.
may mga different parameter settings ang mga simulators
and you can use those.

^ i concur.

yung transformer ang problema nyo, wala nyan sa multism yung mga nagtanong sakin dito pinalipat ko na lang sa proteus pero may point si sir TinTopHack bakit hindi nyo na lang iactual o baka naman ito ay project nyo sa simulation?

agree, may ibang simulation softwares lang na kulang ang library ng components
