Hello It's a basic knowledge, but I'm confused and post a question. I'm going to connect 10 LEDs in a bundle and connect them to one data pin of Arduino. In this case, is the resistance value is (resistance of LED * number of LED)? For example, if the voltage of the Arduino is 5v, the voltage of …

What is the resistance when connecting multiple LEDs to the same pin?

10 leds in parallel, each with a 1k5 resistor will be (more or less) the same as 1 led with 150 Ohm resistor.
