Arduino, Multiplexing, LED's and Resistors. Answered
Ok ok. I'm rather new to electronics, had very minimal use with resistors. I could probably work out which resistor I needed for a series LED connection, but because it's multiplexing, it stumps me on whether it is a series or parallel connection. Pretty much, I'm wanting to run a 5x5 matrix, using these leds (information on it there), through my Arduino, I know some users here have Arduino, but the factsheet, with voltage and currents information is there.
I am wondering, what resistors I'm going to need to use. If you could also say how you calculated that, it would be splendid. Is multiplexing connecting LED's in series or parallel?
I noticed the led link didn't work, but they have the following specs: How bright/dim is 3mcd? I'm assuming it's pretty dim...
# Luminous intensity: 3mcd
# Forward voltage: 2.1V DC
# Forward current: 15mA
