Gikfun 1R - 9999999R Seven Decade Programmable Resistor Board for Arduino EK6019

hello thought do a quick video on something a small project I've done it really didn't take much time but it but it used to cause me a lot of time wasting and then it says something to do is something to do with the things as simple as a resistor and often when I'm prototyping a circuit I'll use something like this and your low AC or certainly in my case I'll always see you know I've got lots and lots of resistors lying around so I have I have often on these boards I've got them line around the workshop here and I'll have them often out I've got a big a big store of them just on the top shelf there and I'll get resistors out there organized so I can get them easily and so on but what I find is you know when I finished a project I would have gone through quite a lot and you know change the impedance of a circuit or song which will often involve changing very varying resistors and so on v
