On Off Timer Circuit Diagram

Here is a timer circuit using common ic 555.

On off timer circuit diagram. A simple timer circuit can be built by using only a single or two transistors. Let us discuss in detail about this circuit. The terminals are a good set of reference points. In circuit uses an integrated circuit timer lm555 or ne555.

Using versatile ic 4060. It has a part compares with voltage 2 group. Programmable industrial timer circuit diagram circuit description. Touch switch circuit using 555 timer.

The circuit is designed to facilitate time adjustment of both charged and discharged states of the relay. In this page we will discuss a very simple yet reasonably useful timer circuit diagram whose on time and off time settings are independently adjustable through. This is done by pressing the inc button. We can use this property of 555 timer to create various timer circuits like 1 minute timer circuit 5 minute timer circuit 10 minute timer circuit 15 minute timer circuit etc.

On pressing the start button the display interfaced to the microcontroller starts showing the relevant instructions. The on time delay and the off time delay are independently settable and this facility becomes the most important feature of a programmable timer circuit.

The figures below show different schematics of simple timer circuits which can be built very easily with few general components.

This is a simple touch on and off switch circuit. On off switch circuit using a 555 timer. Each component should be placed and linked to other parts in particular manner. Details of how to test your finished circuit board are also provided.

So if you reproduce the layout you will have a working timer. The on time of the load is then entered by the user. This circuit has many applications on places where it is necessary to activate and deactivate connect and disconnect an electrical or electronic device. Pressing the button more than once increases the on time.

This on off switch circuit using a 555 timer is simple useful and easy to implement. To fit them you may need to enlarge the holes slightly. These circuits can be used for variety of timing purposes in electronic projects like time delay relay etc. These on off intervals can be adjusted by varying the 555 timer output and number of counter outputs.

Adjustable on off timer using 555 astable mode in this circuit a timer with cyclic on off operations is designed. This circuit uses very basic components like 555 timer and 4017 counter.
