Soldering vs Crimping
Tired of heating up your solder iron and fumble with the pin rows to avoid shortcuts and overheated pins looking in every direction?
Build yourself a connector strip and plug it into your Arduino the safe way
Another handy place is for the external poti connections. Before fixing them into the frame you can make sure to have the connections right (I remember having resoldered these connections about a million times until the servo did what I wanted ...)
You need a crimp plier. You can spend a fortune on a professional one but this 20 USD thing is sufficitient for the few dozen pins and sleeves needed
These are the other components. The pin and sleeve and the commonly usable holders. They come as single pin holder or up to 6 in a row (at least at the shop I know) I bought mine from a german distributor (segor.de) and they are called SLK-2.54. You might find a local store with the same stuff. They are reasonably priced (get 100 for 5 Euros) so its no loss if you brake one.
In my configuration I take about 1.5 mm of insulator off the end of the cable. Then I close the plier fo 2 ticks and insert the pin with the opening upwards and make sure it is plain with the plier sied. (sorry, things are too small for my camera). Insert the cable into the pin holder so you have about 1.5 to 2 mm of insulator included. Then press the plier to the end position. Look at the result. There are 2 clams - one for the inslulater and to take any pull from the cable and one for the braid for the tight contact. The cable may not be too thick, otherwise you might encounter problems with inserting the pins into the holders. Give a few tries with spare wires until you feel confident for using it on the real stuff. Have fun - you gain great looks with your installations!
