Serial input

Since I only have some LEDs to play with I had to be “creative”. So I have tried different ways to program my LEDs to light.

By entering the numbers from 0 to 3 I make one of the four LEDs connected to the Arduino to light for some milliseconds.

Here is the code:

It’s not so easy to see on the sketch below, but each LED is connected to a output, then through a resistor back to ground. Each LED is connected to their own output. I have used output 10 to 13.
