Hi everyone, I am in need of a little help please.
Im looking to build a low res LED screen for a stage set up that is powered by these http://www.usledsupply.com/shop/rgb-32-spi-dmx-decoder.html
The problem I have is that this board only allows for 300mA output per RGB pixel (100mA per led) and this really isnt enough as I need each pixel to be fairly bright maybe 30 or 60 LEDs (10 or 20 R,G & B)
Is there a simple way I can use the output from the above decoder to control a simple MOSFET circuit to amplify the output. I have in mind something similar to this http://picprojects.org.uk/projects/bigmosfetrgb but I only need the MOSFET power part of the circuit. I would obviously have a MOSFET curcuit for each of the 96 outputs.
Am I correct in thinking I could build a curcuit for each output that has its own power supply that powers the LEDs through a MOSFET and the output from the decoder controls the mosfet (as such)
A little help would be great as you can probably tell.
Many thanks
Simon
