What relay to use to switch 12V source using 5V arduino board? Answered
I need to activate
-4 solenoids 12V 250mah each
For as long as 3 hours at a time with a arduino.
-2A 12V source for solenoids.
I know I need a relay but idk which one I should get. If you could suggest one and send me a link that would be much appreciated.
