Relay question (adding relay to Oscars LED driver board) - it works!
JoyMonkey:
I've got these cathode lights hooked up behind my cocktail cabinet's control panels, they work great, but I'd like to add a relay so they only light during gameplay. I can use an AdvMame script to set the Scroll Lock LED to only light up when a game is being played.
My question is how do I get the scroll lock LED to control the cathode light? What kind of relay do I need?
Popcorrin:
I would use a SPST relay, but a SPDT or DPDT would work fine also. It will need to switch off of a 5V supply but it will need to draw a low amount of current, I would find one that is rated at a nominal wattage of 200 milliwatts or so. As far as the current flowing thru the relay to your cathode lights, a rating of 1 amp should be fine.
JoyMonkey:
Do you think this relay would do the trick?
Sorry, I'm a little clueless when it comes to this electronical lark.
Popcorrin:
That should be perfect.
JoyMonkey:
Cool. Thanks!
