Hi, I am working on a school project for my engineering class, and I had a few questions.
I am wanting to power this 12v solenoid valve: https://www.amazon.com/gp/product/B07NWCRM75/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
I read that many of these valves can open with 9 volts. Say I use a 9 volt power supply with this valve. Would it work properly if I used a 2n3904 transistor, resistors, and a diode alone in the circuit, or would I need to purchase a better transistor or a relay to work in conjunction with the transistor, or will the 2n3904 be good enough.
I am very limited on time, so I can't really order anything.The 2n3904 transistors, resistors, and diodes are the only components I currently have. Thank you.
