    Hello
    I tried to simulate this circuit like a million time and it doesn't work :(
    I really need it to work this week , i didn't find the SL100 Transistor so i replaced it with 2N222 . the LED is pulsing when the pin 4 goes high but the buzzer doesn't work . Can anyone try to simulate it in his computer and tell me what i did wrong?

    Please help me

    Thanks
