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 the LED is 2v, and the current is 20ma, the resistance is 150 ohms. Then is it 1.5㏀ if I use 10 leds?
