…and bend it carefully into two right angles, judging the length
If you remember that the grid of holes in the breadboard
are equidistantly spaced at 2.5 mm (or a tenth of an inch if
you’re old-fashioned like me — what’s an inch, Grandad?)
then it becomes easier. A connection over two holes is 5 mm
long, over four holes is 10 mm long and so on — you’ll soon
get the hang of it.
Now, holding the wire at the top, in the pliers, push it into
the breadboard as shown in Photo 5.3, until it lies flush on
the surface of the breadboard as in Photo 5.4. No bother, eh?
Even with a number of components in the breadboard it is
difficult to short circuit connections made this way.
Two other components you need are:

1 x 555 integrated circuit
1 x light emitting diode (any colour).
