What power source does the battery valve need to be connected to
The power to the circuit is controlled by M3 and Q1, so that the circuit doesn't draw any current when off. (If you already have a switch to control the power than you can eliminate M3 and Q1. ) At the start (Vin goes high, red trace ), M2 inhibits the 555 to initially apply full power to the solenoid and pull it in.
FAQs about What power source does the battery valve need to be connected to
Can a 12V battery be used as a solenoid valve?
Ha, yes, the simplest way is not using any switch, but just use your hand to connect the 12V battery to the solenoid valve. USUALLY 12VDC battery (don't use wall wart, which might leak electricity) won't give you a electric shock (assuming you don't have a pace maker in your body). WARNING: me friend hobbyist only.
How do you connect a battery to a solenoid?
As the solenoid is terminated in two wires, you can just touch the wires to the battery terminals. This assumes the battery is beefy enough to provide all the current that the solenoid tried to draw. Caution, if you hold one wire in each hand as you disconnect the battery, you may feel a shock.
