i have a little problem here about solenoid valve 220V AC.
i am using 5v micro controller. i will operate 200V AC solenoid valve operated by 5v micro controller, but i don't know if it will be work properly.
solenoid valve is powered by 220v AC. My question is, can it be change from 220v AC supply to 12v, and how can i make solenoid valve powered by 12v?
Need help here!!! please!
i forgot. here is the flow chart, it goes like this.
5v Controller -> 12v Relay -> 220v AC(i want this to be 12v)
to protect my controller and my LCD for high Voltage which is 220v AC.
