I want to control this solenoid from Arduino, but I am confused which transistors, resistors and diodes to choose. I have seen a lot of tutorials about controlling solenoid from Arduino, but all of them are for 12 volt solenoid or are using some relays which I don't want to use. I will be using 6 of these solenoids for my project.
Most of 12V solenoid tutorials would work here too, if you use just 6V instead of 12V. Post here links to some 12V tutorial, I will look at that and say you, if they are easy to adjust and how.
Or as last resort - your selenoid is rated 6V/0.35A - that is 17.14 Ohm, you can buy power resistor 17-20 Ohm with minimal of 7 Watt (can be much more Watt, no problem - probably big ceramic one) and just connet it in serie with your solenoid and then follow ANY 12V solenoid tutorial verbatim (with this combination in place for 12V solenoid - as it is de-facto 12V / 0.35A solenoid together)
