For items with flat surfaces such as breadboards or battery packs, Velcro or

similar materials are useful to secure them in your box. However, if you

remove breadboards that you have secured in a box with Velcro, be careful.

Breadboards have a thin sheet of plastic or paper on the back that can peel

off if you’re not careful.

You can make custom mounts out of metal bars, screws, and nuts, as shown

in Figure 4-17, which shows also how we mount the motors in Chapter 13.

When stranded wire works

If you’re connecting a component in the lid of

your box to a terminal block on the breadboard

in the bottom of the box, that wire will be bent

back into the box when you close the lid. In this

case, it’s best to use stranded wire, which is

more flexible than solid wire. (Refer to Figure 4-9

for a comparison.)

Be sure to leave enough length of wire for the

box to open and lightly solder the strands at the

end of the wire together before inserting them

into the terminal block so none of them poke out

and short the circuit.
