Simple scheduling tool

IC 555 to IC Timer (scheduling IC) or IC timer.Which may be can be considered quite unique features.To use the time to bring the device resistance.
For the period that desire.
This circuit 555 to the IC number on the circuit Mono Stable. Multi Vibrator. or Delay circuit with operating environment that provides a second output level be The voltage is low (logic “0″) and high-level voltage (logic “1″). When you click the switch S1 pin 2 of the IC will be shot down ground. The motive for the IC1 with low voltage (logic “0″). Resulting in the output pin 3 of IC voltage levels at higher or equivalent supply. it making light LED1. Experience in the scheduling itself. And in setting up or slow down time depends on the R2, C1.And VR1 to adjust the scheduling easier.

Egg timer circuit by IC-555

This is Easy and Mini Timer Circuit ( Egg Timer) by IC 555.
Alarm by Buzzer.
This be mini timer circuit that interesting. I calls that Circuit Egg Timer. By use integrated highly popular circuit number LM555 or NE555 or the number replaces. By VR1 use control the time of the circuit sets the time. When expire buzzer as a result make a noise warn hear. For S1 use for choose that Time or Stand. The detail is other request friends see in the circuit better sir.
