Constructing electronic circuits from a kit can be very rewarding , especially when the build process goes smoothly and the device works rite the first time.
Often though when first starting out making kits it can seem a bit confusing with all those different components  to organize and assemble.
So here is a quick guide to making a typical kit.

Here are the parts and instruction  sheets that I received with my latest kit that I bought. (2007)
LCD display , a bag of components , a bag of hardware and of course the printed circuit board.

Often kits come with a list of parts that are , or should be , included in the kit.
It is possible that some parts are missing , so before starting construction , check the parts off against the list to see what you might have to get to complete it.
This kit has some tick boxes on the right hand side to make this check list easier.
Unfortunately , the instructions in this kit are in German and Ich spreche nicht Deutsches  (I don't speak German) but this list uses normal part numbers , so it is pretty easy to work out.

Also in the instructions you might find these sorts of drawings.
A schematic , as shown above , and a part placement diagram.
Both are real handy , both for construction but also for ease of troubleshooting.
If you don't know much about electronics you will have to trust that these and the rest of the instructions are correct , but it is not uncommon to find errors between these two diagrams and/or the included text.

If you have the ability , it is wise to spend a couple of hours tracing through the diagrams and comparing it to your board to ensure that you find any problems before you start soldering any parts.
