N00b here. I got a 4-digit, 8-segment, 12-pin LED that I'd like to program. Before I even get into the mechanics of using the digits and the segments, there's one super basic thing I don't understand: I've connected the pins of the LED to the digital pins on the Arduino, and I'm able to get numbers to display. In one of the tutorials, it says that if you don't want to burn out the LED's, you need to put resistors between the pins and the digital IO ports. On a basic breadboard (2 rails for power/ground on either side, 30 rows total), if the LED is straddling between both halves of the breadboard, how do I wire it up so that I've got a resister sitting in between the leg of the LED and the digital IO port? If possible, please give me an example using exact breadboard wiring (e.g. A13 to C14, etc).
Not sure which one it is. I think I figured out the answer to my question though (and I feel like an idiot). To get resistors in between the IO pin and the leg of the LED, I just need need to run a wire from the leg to another row, and in that row have a resistor, and the other leg of the resister in another row, and a wire in that row to the digital PIN (right)?
I only have a single LED hooked up, trying to figure out how to hook up a 4-digit LED.
