bibi Posted February 19, 2013 Report Posted February 19, 2013 (edited) Hello fellow, I could'nt find an answer in the forum but I think someone could confirm: I'bought white led that I want to use with some dout. Specifications of the Led are: 3.2/3.4 V 20 mA As they're too bright, I'd like to lower them with resistors. I did some tests and foud that the right brightness would be around 12 Kohm... Is it ok to "mix" the original 220 ohm resistors with 12 K resistors on the same dout pcb?? Many thanks to you guys. Best Bibi Edited February 19, 2013 by bibi Quote
Duggle Posted February 20, 2013 Report Posted February 20, 2013 When you say "mix" you mean have some DOUT pins connected to 220R and some to 12k, right? This is fine. Quote
bibi Posted February 20, 2013 Author Report Posted February 20, 2013 Yes, this is exactly what I was looking for! Sorry, I forgot to mention that... Many thanks to you! Best Bibi Quote
FantomXR Posted March 21, 2013 Report Posted March 21, 2013 Maybe you can use the Dim-command. Take a look at the ng-manual. Quote
TK. Posted March 21, 2013 Report Posted March 21, 2013 Using higher resistor values is the right way, and there is no problem if you use different values for the DOUT pins. The dim option (only available in MBNG) would be an alternative, SW based solution - maybe you will like it (because it gives you more flexibility), maybe you will hate it (because you've to specify the dim level for each EVENT_* entry ;-)) Best Regards, Thorsten.
