NE 555p Where does pin # 1 start?

I looked at the data sheet for this ne 555p chip. I can not figure out where the pin locations are.?

https://www.dropbox.com/s/fitler9s3jt0i64/NE555P.jpg?dl=0

As in where is pin #1 in this picture?

Thanks,
Andy
 
Pin 1 is at the corner nearest the small dot. Count counter-clockwise from there.

Ok, so 5 would be close to the P?

Looks like it is in line with O to me.

Where do you see an O?

Yes, I overlooked the silk screening on the PCB. Pin 5 is in column O and next to the P on the IC.

It would seem you are new to the digital side of things so it would be
probably a good idea to use the chip sockets for when you let out the
magic smoke. If the board you have is not big enough the use another.You
may like to consider using a "breadboard" for developing or trying
circuits, they have the benefits of being reuseable for small non
critical circuits.

Ok. Found this.

It looks like each row of 5 is connected together.

So if I insert an 8 pin chip, that would leave me 3 other points that I could connect other things to?

You insert the chip over the centre groove and have four spare points
either side of the chip that connect to the corresponding pin.
(unless it's a wide chip then you may have fewer holes available)

Like Jason says and that would be a good starter for you. The 4 pins
connected to each pin enables you to connect several components to them
and form the circuit. Like in the chaser example.

All DIL chips have the same numbering system: stand it on its legs with the dot or cutout at one end away from you. Pins are always numbered the same way round.

yes, it'll avoid soldering frying the chip. Also means you can easily substitute chips when you run into faults.

You can use any PCB you like, that one should work.
