Hi guys, how are you doing..
Recently i have done my first spirograph, and as i am total lama in building some circuits i have a little problem with my build..
I used socket adapter as a power supply which give me 3V and 1000mA.. it is enough to drive 3 small motors..
I have used 40-ohm potentiiometers, because it was everything i had..
I have connected everything like on my picture..
My problem is that it is probably paralel conection and if i turn one pot up and my motor stop, then other motor goes quickly.. simply everything is linked and i would like to know how separate each circuit...
I dont know how to describe it better..
I know if i will use 3V battery for each motor+potentiometer separately i will have succes, but how to do this if i want to use this pover supply???
Can anyone help???
Is there some trick, which can do that???
cheers
