I got a question about how to use 2 LED on 1 GPIO (digital output) Turning 1 LED on and the other off. I had designed this simple electronic schematic to turn 1 LED on and the other off, using just 1 switch. Just replace the switch with a transistor and you can use this whit an Arduino or Raspberry.

Here is a Youtube video about this:

NEW: corona shooter game and tutorial in c# Now in corona times, I made a simple game with which you can take your frustrations against the lock down. This is very basic. But very good for learning to program. You can also make it into a different game. Simply by using other drawings. And once you fully understand how it works, you can experiment with adding extra rules. 🙂
