Science Buddies: "Ask an Expert"

I need to build a model dam with 2 solenoid valves. One is for normal activation, the other is emergency. Unfortunately, I have no idea of how to wire this all up and code it. Can someone please explain the wiring and coding to me?(Note: I am using relays for the valves.)

Hi,

This is more than we can really teach you how to do in a forum post. We have a resource page about how to use an Arduino here:

https://www.sciencebuddies.org/science- ... an-arduino

An Arduino is a programmable electronic board that lets you do things like control motors or solenoid valves. However, if you have never used one before, it will be too difficult to jump directly to controlling the valves. We recommend going through the first seven tutorials on that page so you understand the basics. You can then skip ahead to some of the more advanced videos, particularly videos 16, 17, and 19 will be useful in your case.
