Re 3mm Bi-colour LED P/N UF96E I Can''t see any technical specifications for this on your web site, therefore what size resistors would I need to run the green/red portions of the LED from a 12v DC supply? Thanks Adrian Carr
Asked by: Adrian Carr
This is hard to do because you only have 2 leads. You would need to add diodes to allow the current to flow through the red resistor at 330R and a reversed diode to get the current to flow in the green resistor at 390R!

How do you change from red to green ? What does die connected inverse parallel mean ?

Asked by: JOHN
It means that the anode of red is connected to the cathode of green and vis versa. Connect one lead to + and the other to - and one colour will light, connect the other way round and the other colour will light. Connect an AC signal and the LED will glow yellow (red then green, so fast you cannot see the difference)
