555 circuit doesn't work
Your problem can be self-taught by observing the voltages on each pin to see if there is a faulty connection or design or chip.

I just noticed your pin1 is a bottom view or in wrong orientation on schematic. I assume component side is blue tracks.

(I knew a professional Engineer who reversed his layout top to bottom and he went on to be a successful designer and ENG MGR of a large company) 

List the pins and V readings if you get stuck and any other observations pertinent.
