Many electronics circuits and projects for learning in simple ways.

Timer control 1-15 minutes by Triac 2N6075 and LM555-LM358

Most timer circuits. Often used with electrical transformers containing low as 9V and 12V, and use of electrical control relays.but the 1-15 minute timer circuit.It uses a triac instead of electrical control.This can be used with a 220V power house it is not connected to the transformer. Make smaller and easy to use.

Timer control 1-15 minutes by Triac 2N6075 and LM555-LM358

This circuit is divided into three parts: work special high-voltage level, the scheduling and control electrical appliances.

When 220V power supply circuit R1, C1 and ZD1 a special level voltage 220V to rest 10V. The 10V input voltage is power supply to IC1 No. 555. which is part timer.Which is set by R3 and C3 at a specified time period you want.Thus, when switch S1 (Start) IC1 work out a pulse signal generator via the output pin 3 of IC1.The VR1 function timer from 1-15 minutes. Then sent into the period to pin 2 of IC2 number LM358. Which is controlled electrical appliances.

The output of IC2 to expand a pin 1 with a voltage of about 5V. to stimulate the pin to the gate (G) of a TRIAC T1. which a TRIAC acts as a switch on and off electrical appliances.When pressure on the to stimulate pin G a Triac will conduct between MT1 and MT2 pins result appliances are working fluorescent light. And after the set time-out quits and IC2 to stop the flow with the Triac. Which IC2 stopped work, simply hit the switch S2 to reset or unplug any.

If you you want to see a simple timer circuit using IC-555, please below.

555 IC Timer control relay Switch

This is easy Timer circuit projects. Control by relay. It use IC 555.
This the circuit sets the time to are simple one that interesting , because use IC LM555 Timer be 8 pin integrated circuits. But can set the time accurate can use by fine while VR1 , and use the the Secretariat of the Senate reset the system is new. When want to set the time new every time for electric appliances supervision as a result can control with Relay Switch normal.

  1. I wanted using 555 one minute on and off 5 seconds
    in all the case only on timer is given where off timer one has todo manually.

    needed is on and off timer on time 1minute and 5 seconds off timer auto matically. no manual response.

  2. What type of software can I use to simulate this circuit?

  3. What type of software can I use to simulate this circuit? Please reply my comment ASAP T-T

  5. Sir, what should I change to make it just up to 6 minutes?

  6. I really like how clean your circuit is. You should be switching the live side of the circuit not the neutral. Lamps for example will be live when you “might” change a bulb etc.

  7. I have an electric air compressor for my basement shop that supplies compressed air to various outlets for air tools and gadgets. It is always plugged in and I like to keep the system comprised of mostly schedule L copper pipe charged with compressed air for immediate use when I need it. The weak part is where at most outlets a rubber hose is plugged into the air line. This is a weak point because should the rubber rupture, the compressor would run until it burned out, if it ruptures while I am not there.

    Would I would like to build is a device that would automatically shut off the power to the air compressor if it ran for a time longer than it would take to fill the tank, which might indicate a rupture. It should be variable, say from 1 to 10 minutes, depending on the usage and size of the compressor. I am thinking some type of timer circuit that would start a countdown when the compressor starts and reset itself when the compressor stops. But throws the circuit anytime the run time exceeds the time set by the operator, and have to be reset manually. Also, should be inexpensive.

  8. what is the L1 in the 1-15 minute timer circuit?

  9. 8-3-430/1/16, Yellareddyguda, Near BSNL Off,Amerpt

  10. What is the relay type used in 555 timer, whether it is 6v or 9v relavy. Please clarify. What is the minimum and maximum time this works.
