Controlling an LED by typing


I just started with my arduino today and I'm trying to figure out how to control an LED with my keyboard. I simply want to type "on" and click enter and the LED will turn on and vice versa. Could somebody please explain how to do this? pls send help

Thanks! :)

Do the Serial input basics experiments.

After that, several things at the same time.

Understanding the concepts presented is an important stepping stone to doing much more.
