There are some slight variations of NE555 wiring posted over internet, so I think I might have done something wrong with wiring the chip NE555.
When you boil it all down there really are only two basic 555 configurations:
(1) Astable - typically has a resistor between pins 6 and 7
(2) Monotable - typically has pins 6 and 7 tied together
I use a common configuration when I draw my 555 circuits and that makes the similarities (and differences) easily discernible. My configuration is very similar to yours except I have two connections on each side of the box. I draw pin 5 on the right, under pin 3 and I put pins 2 and 5 on the bottom, with pin 2 on the left and pin 5 on the right.
Your 555 circuit looks OK except you should probably tie or pull pin 4 (reset) high and you should put a small capacitor (0.01uF) between pin 5 and ground.
