What is incorrect with my 555 LED flasher circuit?
That doesn’t look like a 470k resistor in your photo.  It looks more like a 470 ohm.  Do you have a multimeter to test it?

The correct colours should be yellow, violet, black, orange in the 5 band colour code, or yellow violet yellow in the 4 band colour code.

The brown band indicated it is a 1% tolerance resistor on the 5 band colour code.
