How to control a solenoid? Answered
I have a tiny solenoid from an automatic air freshener that I want to control manually.
The solenoid acts as a valve that opens when fed 5v, and closed when no voltage is present.
On the factory board, there's a timer that triggers the solenoid every few minutes for a fraction of a second (opens and closes so fast it just sounds like a click).
What is the simplest way (No Arduino, Raspberry, etc.) to make a 5 volt pulse to make it go "click" on the push of a button? Further more, how would I control the length of the 5v pulse? I want to be able to control the amount of gas it passes (Pun intended) when activated.
Any information would be helpful, and a circuit diagram would be greatly appreciated (I can read diagrams but can't design a circuit).
