That is a tutorial circuit. It is meant to teach you how a 555 works, and the LEDs are there to provide a visual indicator of what is happening. You are supposed to be able to figure out how to make it work for your application, people are not going to draw your project up for you with as little information as you gave.why is that led??? is it necessary?? i need to switch off motor after 10sec once its start.. so can you guied me pls??
A thread belongs to the OP (original poster). Trying to take over someone elses thread is called hijacking, which is not allowed at All About Circuits. I have therefore moved your thread to one you had already started on the topic.sir, can i switch of motor after 10sec by using 555 timer ic??? can you help me out about connections???
