I am have circuit with Arduino NANO and I need to control air valve, which is powered with 12 Volts and 0.8 Amper. Problem is that Arduino NANO is powered with 5 volts. I want to use transistor to achieve it. Which one the best option in this case ?
Thank you for help
PS: I need ON/OFF states only.
PSS: I want to use transistor, not relay, because transistors are quicker.
