Start Electronics Now! Part 4:
Beginner's Shopping List

Created on: 27 July 2012

Updated on: 2 November 2012

Part numbers from RS Components have been included in this list as examples as they have branches all over the world. Where the RS Components link leads to the Allied Electronics website, the part numbers are not valid.

Links to parts and tools at have also been included.

You can also search any other electronic component supplier on the Internet using the part name or value.

The RS component stock numbers may be for quantities of 1, 5, 10 or more. First select your country from the main RS component page and then copy and paste the stock number into the search field. Also do your own search on the RS website to see if there are new parts or different quantities available.


1. Breadboard
(RS Components stock number: 748-5300 (breadboard and wire links))


2. Side-cutters
(RS Components stock number: 536-379 or 536-420 or 536-329)


3. Half-round-nose pliers
(RS Components stock number: 536-442 or 536-391 or 536-385)

4. Soldering iron
(RS Components stock number: 604-545 (25W) or 231-5376 (15W, UK plug) or 494-9498 (25W, UK plug) or 231-5398 (18W, UK plug)) These are just some examples of soldering irons, shop around, also buy spare tips, especially chisel tip if not fitted. These are all mains powered irons, 220 to 240V. Be sure to buy a soldering iron that is rated at the correct voltage for your country and has the correct mains plug. Also look at soldering iron stations.

5. Soldering iron stand with cleaning sponge
(RS Components stock number: 431-4139) This is only needed for a stand-alone soldering iron. If you buy a soldering iron station, a stand and cleaning sponge should be included.

From (120V soldering iron stations for USA):

6. Solder wire
(RS Components stock number: 436-4881 (0.5mm) or 295-4814 0.7mm))

Where to Order Parts

You may have a local electronics shop that can supply some or all of the parts. There are also many on-line shops that you can order parts from.

Things to Consider

Where you order from will depend on price and availability of parts. Also consider postage costs if you are ordering online. Some suppliers may have more expensive parts, but free postage.

If you are ordering parts from another country, you may have to pay import duties or taxes, depending on the laws in your country.

Where to Shop

RS components have branches all over the world.

Mouser is an example of another on-line shop. have many electronic parts, kits and tools.

Use a search engine to find a local or on-line electronics shop near you.

The Arduino Distributors page lists many more electronics shops that sell Arduino boards and probably other electronic parts too.
