The leds in this app are configured at 2v and 20ma. By using Ohms Law the current limiting resistor would be 9v-2v=7v÷20ma=350ohms for the current limiting resistor value.

Hi Wyoelk, you are correct. I made this circuit to replicate one made in real life (though not running the LED at its max current rating). Nevertheless, I was also trying to show how going a bit over the needed resistance value still allows the LED to turn on and is less taxing on the component. Thank you for pointing out the resistance and Ohm's law, I'm sure it'll be helpful for anyone checking this out!
