The 555 Timer is presently the foremost wide used physics part. many sorts of comes is finished it. If you recognize a way to make out well then completely different electronic circuits will use it. Plus, you’ll be obtaining eliminate muddle you don’t want. Timer IC is associate degree eight pin IC. nowadays i will be able to show you the way you’ll be able to build slightly switch with 555 timer IC. it’s terribly straightforward to form slightly switch with 555 timer IC. By creating this switch you’ll be able to flip any load on and off. you need to use a driver circuit with it to run a load of a lot of amperes or AC load. Below is that the pin diagram of this 555 timer IC.
Now I have shown below the pin diagram or connection diagram of how you can make a touch switch with this 555timer IC.
Touch will be created if you connect according to this connection diagram. Here I have shown with only one LED. If you want to run AC load you need to use driver circuit.
