This is a design for simple timer circuit. This circuit can giving 10 minute of the timer. This circuit is based on 555 IC for the operation. This circuit can connect with microcontroller for practicing the programming. This is the figure of the circuit.
When ever you need to get an alarm or intimation after ten minutes, the circuit shown below can be used. The circuit is nothing but a mono stable multi vibrator based on IC NE 555.When ever you press the reset push button the green LED D1 glows after 10 minutes. The time duration can be set by varying the POT R5. The switch S1 can be a push button switch. The IC1 must be mounted on an IC base.
