    I'm (very slowly) working my way through the exercises in Make: Electronics but am having trouble with an experiment involves making a circuit with a battery, a potentiometer and an LED with crocodile clips and then measuring the voltage and current using a multimeter.

    I don't know if the components are too small or what but the problem I'm having is that it's too fiddly for me to actually do it as well as handle the multimeter to get readings. Things either won't attach or they're too close together and there's a danger of shorting or they actually do touch so I have to keep adjusting things and it's just ridiculously fiddly. The main problem is getting things attached to the potentiometer as the terminals are very small and close together and the crocodile clips seem to be rubbish for the job.

    Do I have any alternative ways to do this? I'm a total beginner and so I don't know how to solder yet.

    Try doing a Google or eBay search for "Mini Grabber test clips"
    They should solve your problem.
    They can come as discrete clips (which require soldering leads on, or with leads attached.)

    Clips are entirely the wrong way to go about prototyping pretty much any circuit. You're right, they're clumsy. They're not meant to be used at every connection. Instead, purchase a breadboard. They're extremely helpful and tidy. Purchase plenty of jumper cables as well, or make your own. 22 AWG is the size you want, but 20-24 should also work.

    If you've never seen or used them,
    Breadboards typically look something like this:http://ferretronix.com/stuff/breadboards/breadboard_holes_91.jpg
    And Jumper cables, like this: http://i00.i.aliimg.com/wsphoto/v0/...readboard-Jumper-Cable-Wires-male-to-male.jpg

    Another alternative is wire-wrapping, but I've never tried it.

    How would I go about hooking up the potentiometer to a breadboard?

    You can solder a breadboard jumper wire to each terminal of the pot.
