Ok so , its the same result.it moves and inch , even lesser then an inch i have the board wired exactly like the picture in your guide, the pot too ,
I know it's tedious, but if you could go through STEP BY STEP and tell me what you actually did with the wiring (not just "I did what's in the guide", but what you actually did, with all the wire connections and ideally photos), I might be able to spot something that was wrong or missing in what I said in the guide.
Same goes for the calibration step. Trying to talk "virtually" like this, it really helps if you can pretend I'm a 3-year-old and I don't even know what a mouse is, so really tell me in excruciating detail every exact mouse click you're doing so I can make sure I'm following along properly. Again, I might be able to spot the step where something is going wrong.
i also tried switching wires around , at one point when one of the wires made contact it turned off the pinscade and when i disconnected the wired it turned back on ,
I sounds like you shorted power to ground, which will trigger the overload protection on the USB port and cut all power to the port. That will naturally reboot the KL25Z. Most USB ports have little circuit breakers that automatically reset when you do this, so there shouldn't be any harm done, but I'd actually kind of recommend against messing with the wires too much with the power on. There are probably ways you can short things out that are less benign.
when you take off the wires at least two of them the whole meter goes hay wire left and right
That's all to be expected, actually - what you've done by disconnecting one of the wires is made the circuit incomplete, which creates a randomized voltage on the sensor input port. The randomized voltage will cause randomized readings on the port, which will cause randomized readings in the software.
but when i go into the settings menu where u can calibrate it , that is all that it is doing moving kess then an inch ,
When you say "it's moving less than an inch", I hear "it's moving!", which means the potentiometer probably isn't broken. If the device were broken you probably would be seeing either the same kind of randomness you see when you disconnect some of the wires (for exactly the same reason - "broken" could mean "something's not connected inside", which would yield the same results as "one of the wires is disconnected outside"), or no action at all. If you're seeing "moving an inch", that sounds like it's actually working and you just need to complete the calibration process.
