Hi Guys.
I bought a 12 pac of dual color (red/green) 3mm LED.to make signals to note switch positions. I need to figure out the resistor value needed to light them properly.I have a 12V input The paperwork I have is a little tricky for me to follow it says the LED has the following...
------------------------------------
Forward current
Red 20 mA
Green 25mA
(peak 60 mA)
----------------------------------
Forward voltage
Red 2.1v -10mA
Green 2.0 - 10mA
Reverse Voltage
3V
What value resistor do I need?
thank you!
