Hi all,
First post on this forum and I'm a bit of an electronics newb. I started writing long post, but will just give details and if you'd like the full version, let me know.
I'm modding a DMX LED color changing light so that it uses RGB LEDs.
There's a 4 pin connector that bridges the power/DMX circuit and the LED board.
R-G-B-VDD
Max voltage for RG&B - 14.5 Volts
MY RGB LEDs:
Forward Voltages - Red-2.0, Blue-3.5, Green-3.5
Forward Current - 30ma
Common - Cathode
I have calculated for the correct resistors and I am aware that the current draw multiplies per how many LEDS I connect together. I know I muse run these in parallel and that the original circuit was designed to power LEDs in series.
Any ideas on this one?
Should I have gotten Common Anode?
Should I dig further back on the DMX board and pull signal from there?
Do I need to boost the current coming from the DMX board?
What is the average air speed of a laden African Swallow?
Again, I will be more than happy to answer any questions if it will shed light on a solution.
Tony
