<div>I am using the Simkits multi-controller and have been playing with the 5v LED outputs. The LEDs are cool, (got the marker lights working last night) but I got to thinking, it would be great to use those signals to toggle my 28v bulbs. There are a couple of places where LED wont work in my sim.</div> <div> </div> <div>But this exposes my lack of electronic knowledge so my question is,</div> <div>what would be the simplest way to toggle a 28v DC circuit with a 5v 20mA DC circuit?</div> <div> </div> <div>Justin</div><p>
