I have a multimedia device with an external port that has 8 outputs. These outputs can be programmed to trigger (+3.3vdc) at any time during the presentation or in response to 'buttons' on a touchscreen. My intent is to use these outputs to trigger small lighting units. I need something on the order of an SSR to control each individual light. The lights operate at 12vdc and although they are LEDs, they are non-polarized.
I have 56 of these, so economy is a factor. I tried an SSR with an AC output (because I couldn't find a cheap one with a DC output) and it would turn the light on, but not off.
I next tried a ULN2803A which responded to the trigger voltage but would only illuminate the fixture only slightly.
I'm stumped. Any ideas?
