Hello,
I have designed this circuit,
and placed a buzzer in parallel with the LED, however when i am applying input voltage through a 9volts battery the delay between beeps is quiet good and LED is also flashing fine but when i am supplying input voltage of 4.8volts (through 4.5volts adapter) then there is no time delay between the beeps of a buzzer and LED remains on.
can you please explain why is this happening ? and how can i calculate the time delay of the circuit myself ?
