Sebo Posted March 7, 2010 Report Share Posted March 7, 2010 Hi: Some time ago I finished my MIDIbox CV, but the LCD Backlight never was very bright, the LCD is Winstar WH1602B, but the color scheme is not the same as in the Winstar site, mine is blue background with white characters. I used another one for other project and worked OK, but this one is barely readable with this dimmed out backlight. Finally I decided to add one or two white LEDS at each side of the LCD, and I'm wondering wich is the better way to power them. Can I simply connect the LEDS directly to the pins B- & B+ of the CORE V3 (PIC based), just in parallel with the actual backlight, and without any current limiting resistors? or is it better to connect them directly to 5V with some current limiting resistors? Thank you. Quote Link to comment Share on other sites More sharing options...
ilmenator Posted March 7, 2010 Report Share Posted March 7, 2010 or is it better to connect them directly to 5V with some current limiting resistors? I would go that way and make the resistor adjustable, so that you can adjust the brightness any time you like (or need). ilmenator Quote Link to comment Share on other sites More sharing options...
