It would seem that the output of the timer isn't able to clock the counter (mixing and matching TTL and CMOS isn't for beginners). The 10k pullup resistor fixes that problem. The 0.1uF capacitor shouldn't be required.it works well but i don't know why. how they work?
But if I remove it, it shows an error message in multisimIt would seem that the output of the timer isn't able to clock the counter (mixing and matching TTL and CMOS isn't for beginners). The 10k pullup resistor fixes that problem. The 0.1uF capacitor shouldn't be required.
What is the error?But if I remove it, it shows an error message in multisim
Is the buzzer component actually a buzzer? Or does it need to be switched on/off to make a sound?i run the convergence assistant but it couldn't solve the error
buzzer need to be switched on to make a sound.Is the buzzer component actually a buzzer? Or does it need to be switched on/off to make a sound?
As a test, remove the buzzer and C2.buzzer need to be switched on to make a sound.
i removed it both, but error still occured. i did it on the breadboard too, but LED lights up sequentially whether switch is on or not. (4017 keeps counting when switch is off) I think capacitor seems to be needed.As a test, remove the buzzer and C2.
Is the pullup resistor still installed?i did it on the breadboard too, but LED lights up sequentially whether switch is on or not. (4017 keeps counting when switch is off) I think capacitor seems to be needed.
Sorry for the late comment. i installed the pull-up resistor but still error occurs on multisim.Is the pullup resistor still installed?
The capacitor isn't needed.
Install it as you have it in Multisim.i want to install the buzzer so it can make sounds when it's working. what should i do?
buzzer and C2 0.1uF capacitor?Install it as you have it in Multisim.
On your breadboard or in Multisim?when i install only buzzer, it didn't work.
The capacitor puts a capacitive load on the timer output that isn't required.how capacitor makes the buzzer work?
