Circuit Diagram 5-30 Minuts Timer using IC 555

Robotronicdiagram. - This is one of electronic circuit diagram of 5-30 Minuts Timer using IC 555 like in Figure 1 below. The main component in this circuit diagram is 555 IC and other components. In here we will show you also the component parts used and the simple description of this circuit diagram and the last we will give you link to read more about this circuit from original source. 

Circuit Diagram 

Component Part
  1. NE555 IC
  2. Resistors
  3. Capacitors

  5. Switchs
Description

Circuit diagram like in figure 1 above is Circuit Diagram 5-30 Minuts Timer using IC 555. According Eleccircuits site describe that this timer circuit uses a 555 IC timer number. This small,compact and portable. For the snooze alarm by buzzer when some 5 to 30 minutes. It makes clear the brain is ready to continue to work.

When the switch S1 to enter a power supply circuit, it will be ready to go.The circuit includes a circuit IC1 Mono Stable for the delay.The switches S3-S6 as election time.If selected by S3, 5 minute timer.S4 is located at 10 minutes.S5 timer for 15 minutes and S6 is scheduled for 30 minutes.If you want to set for 10 minutes, switch S4 is followed by a switch S2 to start all the time.Work is that when switch S4 will allow the current flowing through R4 will flow through the switch S4 to C2.Acting with a delay charge and discharge completely.Then send a signal to Pin 7 and 6 of IC1 resulted BZ1 beeps Buzzer out.
