LED Board Control Answered
Hi there. I salvaged 2 boards of LEDs from an old LED can at work. They were previously DMX, and have an array of red, green, and blue LEDs. There are four leads coming from the board, +, -, a dashed line, and an unmarked line. I am looking to integrate these with another project, but am unsure how to go about finding how to control them electrically. I was thinking it might be digitally controlled right on the board, but I see no IC.
All I am looking to do is figure out where voltage needs to be applied in order to have different RGB levels. If I helps, the number printed on the board is FT140PCB GS. I am able to attach an image if that would be helpful.
Any ideas of how to go about this? Thanks a lot, anything would help!
