Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite I want to control a total of five solenoid valves with my Arduino. The solenoid walves operate at 12 volts and have a power consumption of 5 watts per solenoid valve, which equals a current of roughly 420 milliamps. My idea is to use a ULN2003A transistor array to do this. The ULN2003A datasheet says it supports voltages of up to 50 volts and a maximum current of 500 milliamps per output. My question is: Is the ULN2003A with its 500 milliamps maximum current rating per output sufficient to reliably switch the solenoid valves? I'm asking because solenoid valves are inductive loads and if I'm not mistaken, they are subject to inrush current that far exceeds the normal current. arduino share asked 5 hours ago Chris1309 6 1 New contributor Chris1309 is a new contributor to this site.

At one point, he's restarting the game and the very first three easy ships appear, and send him a message with a picture of some weird eggs with legs and something like "Please don't shoot! There are children on board!" He looks into it more, and instead of just being a glitch he finds out that there's actually a world inside the game, and each time people reload the videogame they're actually fighting new, different ships of an alien species and they're running out and almost dead. The kid transports into the other world somehow, and meets with the alien queen (they're bugs of course, I think the author was a fan of en...
