Hello:
I feel outclassed by posting such a simple project here.
I am currently debugging some MOI boards in Dell systems, and need to monitor when a few circuits are activated and deactivated. They are in a hard-to-reach place, so I would like to wire in parallel a few low-amp LEDs to indicate when the circuits have been activated.
The circuits are 12VDC, and draw about 2.5A each. Therefore, a couple of low-powered LEDs would not affect the circuits' power draw at all.
This would be a throw-away, one time use. So I'm looking to build it on the cheap. I'm assuming the following parts:
* Low volt LED (could you recommend some specific ones, Radio Shack perhaps?)
* A resistor to place inline to lower 12V down to ~3V, or whatever the LED needs.
Thanks again!
