Hi,
I am looking for a Beeper Circuit (using a Piezo Buzzer/Sounder) which when
triggered by a logic high should produce two beeps (pip-pip) every 5
seconds. The sequence must be like pip-pip:5 secs delay
ip-pip:5 secs
delayip-pip......Will prefer a circuit using dual-timer 556 or CMOS/ TTL
logic gates. Any help
appreciated - Tks/ Darrin
