The +5V and ground connection shown in the circuit diagram can be obtained from the 5V and ground pin of the Arduino. The Arduino itself can be powered from your laptop or through the DC jack using a ...

Be sure to verify the polarity of your LED light strips before you start making connections. Connect the positive lead of the LED light strip to Arduino’s 5V pin, and the negative lead to the GND pin.

Being able to use one of your old projects to make a new one better can be quite satisfying. [Steve] from Hackshed did just this: he integrated an Arduino based webserver into a new network control… ...
