Pushing on P2 for 1 to 5 seconds, the circuit starts and then will switch off after about 35 minutes. This time delay can be varied by changing R1 and/or C1 values. P1 will stop the timer if required.

A 5 volt voltage regulator is used for providing 5 volt to whole circuit. And a 9 volt battery is used for powering the circuit. Rest of connections are shown in the circuit diagram. Working. In this ...

Monostable multivibrator (MMV) mode of 555 timer IC is also called Single shot mode. As the name indicates, only one state is stable and the other one is called unstable or quasi stable state. 555 ...

S1 can be a tilt-sensitive switch with mercury if that will be used as a kitchen clock. With the buzzer on the power consumption of the timer alarm will be around 10 mA. Timer Alarm circuit diagram.
