I suspect that the simulation error is caused by 4040 behaving strangely in Multisim. The error persists even after fixing the bridge. My main question is whether this will work as expected when I turn it into a PCB.Hi kuji,
Are saying your circuit does not work.?
If not, what error do you see.?
E
Edit:
You have a join error.

I don't know. I received this assignment in school and I have to have the finished product ready within 14 days, so I'd rather ask if anyone experienced sees an error in it, so I don't have to search for it laboriously later.What do You expect ?
What is the purpose of this Circuit ?
10hz is almost too fast to see.
Most likely the LED will just look kinda dim.

If you .inc the attached file below instead of CD4000.lib, all CMOS part voltages will be equal to any supply voltage node labeled Vdd.On the CD4040 the parameters are entered in a panel
I know, but I have been given these instructions.If you wanted to be really smart you could clock the 4040 from the 50Hz input and eliminate the 555.
Thank you very much, this is brilliant.
I also found out that I don't have pins 16 and 8 in my schematic in Multisim, and the bridge has already been fixed. The LED power is a concern, but I will solve it using a transistor as suggested by EricGibbs. TyThe output High of an old 555 is 6.8V when it is powered by 8.2V.
The output high an a CD4040 is only a few volts and only a few mA when loaded with an LED and powered by 6.8V.
Most of your schematics have no Power (pin 16) for the CD4040.
Your first schematic has D1 shorted.
Maybe the simulated model of the CD4040 shows an output at the 6.8V with many amps of current.
Yes, he's a bit silly, that's also the reason why I'm asking here and not him.Beware if you or anyone around you suffers from epilepsy! 5Hz-10Hz is the range in which flashing lights can trigger epileptic seizures. You might want to point this out to whoever set your assignment.
Welcome to AAC.Should this work?
