Oh there you are. Perfect! At first, we have to download the Arduino software. We

Now, I’m gonna show you the Arduino. That is a pretty decent thing. The Arduino-Board

Current always flows from plus pole to minus pole. You already know that from batteries.

But now let’s really build something. Take two LEDs, two long patch cables, a resistor,

You already used the breadboard but we totally forgot to talk about it. We can

Until now we only used the Arduino as power source. Now it is time to

Did you build the circuit from Unit 6? Perfect! If you already connected the Arduino

Did your LED light up? Good work! Now let’s make it blinking. In order to

A very important thing in programming are variables. I guess you already know it from

A great thing in programming are loops like the for-loop. It repeats tasks like blinking
