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?

you gonna have 3mA drawn from MCU pin then shared between 10 LEDs, don’t think it will be enough to light up any
