I am trying to build a simple LED flasher circuit using 555 timer IC. Tried building it on breadboard and simulators several times but that is not working. As I am a beginner I think I am making some mistakes but with a lot of efforts I couldn't find that. Can some one please have a look to the breadboard circuit that I have build on simulator and tell me what is the problem in this circuit and why it is not working.
Here I have used 4k resistors between pin 6 and 7. and used 1k resistor with LED. Also connected pin 2 with pin 6 which is not visible in the image. Thanks
