hi
i want to build a buzzer circuit that gives beep sound and glows one led for 1-2 second at an interval of 5 second with 555 timer.
please give me a circuit diagram or any other alternative circuit using another ic which should cost low
Hey Pradeep where do I fit buzzer?
In place/paraller of 'led' or ''led1and r3 combination''?
I had brought buzzer which works in range of 1.5-27 volt.
Can u post pcb layout also.
Thx in advance
buzzer can be fitted on pin3 to gnd (i mean -ve of battery.) place +ve of buzer to pin . this small ckt can be easily assembled on veroboard . general purpose pcb

thx in advance
