Hi All,
I have designed the circuit below. After some time, the top signal into the AND gate goes HIGH, causing the leds to flash and the buzzer to beep.
I need to adapt the circuit so that when the top signal into the AND gate goes HIGH, the buzzer beeps once only (or only a few times) then stops, while the LEDs continue to flash.
Any ideas?
I though about a one-shot 555 Timer but I'm not sure. If it helps, the two signals into the AND gate are from a 4060 Timer IC.
Thanks.
