I’m just getting started with Arduino, and would like to learn a simple way to use it to control some numeric LED digit displays that I have lying around.
I don’t have the specifications of the LEDs; all I know is that they’re common cathode, and that their voltage ratings are somewhere between 1V and 2.3V.
From large to small, the following text is imprinted on their sides:
KPS-1106 / A S R N D (corresponding to each lower leg)
I couldn’t find their specifications by doing searches with this text on the web. I haven’t dealt with numeric LEDs before, so I’d appreciate links to any common information regarding how they work as well.
