Basic Timer Control with NE555
As friends many take an interest the circuit about IC 555 which be integrated highly popular that circuit. I then lead the circuit sets the time be Basic Timer Control with NE555 come to present again. By it basically the base of the circuit sets the time work instruction easily initial. Press S1 for a already moment liberate for initial setting the time (Timing Cycle) Relay encouraged work (Pulled in). Until anniversary completed work. The R1 and C1 control length of while delaied keep. If use the value C1 very the time long ago go up This circuit meets to wasp Logic pulse with sir. Request have fun the circuit sets the time this easily please sir.

Time Delay Relay by 555
A time delay relay is a relay that stays on for a certain amount of time once activated. This time delay relay is made up of a simple adjustable timer circuit which controls the actual relay. The time is adjustable from 0 to about 20 seconds with the parts specified. The current capacity of the circuit is only limited by what kind of relay you decide to use.

Time Delay Relay II by IC 4011
When activated by pressing a button, this time delay relay will activate a load after a specified amount of time. This time is adjustable to whatever you want simply by changing the value of a resistor and/or capacitor. The current capacity of the circuit is only limited by what kind of relay you decide to use.
