Hi,

This week some of us were able to engage in playing with “Arduino Uno”. I was one of them, luckily.

SO what is Arduino?

“Arduino is an open-source electronics platform based on easy-to-use hardware and software. It’s intended for anyone making interactive projects.”

In short, Arduino(the name is an Italian masculine first name, meaning “strong friend”) is a module that better engineering. So what matters to Arduino are sensors, codes and your imagination!

What I’ve done today are 1,make one LED blink 2, make two LEDs blink alternatively 3, control one LED by a switch. (download your environment here:http://arduino.cc/en/Main/Software and begin Control-C&Control-V codes,)

SO here I just want to talk about experience learned today.

1, After you finish typing code(or pasting code:D, in most cases), do “compile code”, see if it is successful and then save it, finally upload it to your Arduino. BTW, manually chose the right Serial port (go google the right one for your Arduino series)

2, the circuit plot is really important,

Don’t look at the nasty picture above, go find some like this:

Usually, Red- positive. Black- negative. They make a circuit (go through red to black). Green refers to functional pins. (These “blueprints” are powered by  Fritzing)

Arduino is a very easy-to-use platform and begin your journey:here:http://arduino.cc/en/tutorial/blink
