In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Beau Schwabe wrote: One thing that I notice from the schematic, is that ALL of the LED's are in parallel. This is usually a no-no and should be avoided. With a +5V supply you can place 2LED's in series with a current limiting resistor, or you might be able to get away with 3LED's in series if the Vled is less than 1.6V with a small current limiting resistor. If you choose to use the +Vsupply instead of +5V, then you might be able to get away with more LED's in series. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=88380#m103872 Need assistance?
