Hi!
Complete newbie here. I will need some (3 or 4) really long jumper wires with heads (female-male). Length 1m or even 2m. Are these available anywhere please, most are around 30cm long. If not, how easy is to make these myself please.
Thanks
You can buy an inexpensive kit that includes crimp on male and female DuPont connectors with shells and a crimper tool.
And some wires of different colors (IDC rainbow wire).
It takes a bit of practice to get good crimps, but not a lot. I ruined maybe 5 or 7 before I got the hang. On thinner wire, double the stripped ends so there is more to grip.
If you plan to stick with the hobby, buy a crimping tool.

If this is a one time thing, cut an existing wire in 1/2 and add your extra length in the center.
I like to ask why you need them. If it's for data, be aware that long wires are more susceptible to pick up noise from the environment.
Take a 30cm wire and cut it in half and splice in whatever length you need.
Or you can buy a crimper, pins and housings and roll you own ends.
Hello
I´m using patch cable and a screw adapters.
Have a nice day and enjoy coding in C++.

Thanks all for your replies! It appears I will have to make my own but looks certainly doable.
I want to use a water sensor with my arduino, but the place where the droplets appear is very awkward/tight, I am lucky if I can fit the sensor there alone. The board has to be placed somewhere nearby but unfortunately not within 30cm. About 1m long jumper wire should definitely give me a lot freedom but i do take your point about the environment noise. Need to test it first I guess. Many thanks for helping me
How quickly do you need to act on the presence of water? If "immediately", the following isn't relevant.
If you can tolerate a delay, then simply only take action on the presence of water for a defined period. That should filter out common noise effects, if any exist.
