So there was a cool project in MAKE http://makeprojects.com/Project/PS-2-You-LED-Sign/1069/1 that used a PS/2 to control a sign. I'm trying to make an LED sign with the same LED modules http://www.sureelectronics.net/goods.php?id=1118 but adapt it to be controlled using the Arduino Ethernet board. The software I can probably figure out, but the electronics (simple as they are) can be over my head.
Silly me thought I could just plug the +5V and ground right into the LED module and all would be well. The board shuts down so it seems that the LED module is drawing too much power from the board. The original project uses an ardweeny with a voltage regulator that runs everything. For this the plan was to plug the arduino into the ethernet and use the DC jack to power the whole thing. I figured the onboard voltage regulator would be sufficient.
Can anyone suggest a good way to power this whole thing?
