IO1-LED1 and a resistor, say R1 (assuming R1 is the resistor in question), whether R1 is connected to the Anode (A) or Cathode (K) side of IO1-LED1 does not change the fundamental operation of limiting current to the LED. The important part is that they are in series.IO1-LED1 where:IO1-LED1:A goes to the +V (could be 3V3 for a 3.3V LED circuit).IO1-LED1:K connects to R1:P1 or R1:P2 (Whichever pin to accommodate the series connection logic).IO1-LED1:K to R1:P1 (assuming P1 is the input side of the resistor).R1:P2 to GND.3V3) is appropriate for your LED and resistor combination. The resistor value should be chosen based on the LED's forward voltage and desired forward current.3V3 represents a +3.3V power net in your project, which is typical for logic circuits but should be confirmed as suitable for your LED.Reviews
