Simple 555 signal generator ...

Hello.

I am trying to build this circuit :

http://www.rmcybernetics.com/projects/D ... erator.htm

on breadboard without using the 14-pin IC socket (because it doesn't lock down in the board).

I have three things i'm unsure of :

1. What is supposed to be connected to the middle leg of my (3-leg, linear) pots. Is it the chip pins or resistors ?

2. The circuit diagram has connecting lines running from some components to unused legs of the IC socket, what should i be doing there ?

3. What is the best way to test this circuit's output ?


Thank you,

Gary.

Hurray !

I figured it out :)

Resistors go to middle legs and the connecting lines to unused legs on IC socket don't matter.

I tested it by attaching a small speaker.
