Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

#define redPin 9 // Pin for the red RGB led pin #define greenPin 10 // Pin for the green RGB led pin #define bluePin 11 // Pin for the blue RGB led pin #define potPin_red A2 // declare pin for the ...

Circuit Diagram: Connections: Connect the +ve end of the red led to pin 11 then connect the +ve end of the blue led to pin 10 then connect +ve end of the green led to pin 9. Take all the grounds ...

Connect the positive lead of the LED light strip to Arduino’s 5V pin, and the negative lead to the GND pin. If you’re using an RGB LED strip, there may be additional leads for red, green, and blue.

The next example is control of RGB Led. For this purpose, we connect the RGB LED diodes to the D9, D10, and D11 pins through the appropriate series resistors as shown in the diagram. Then we start the ...

As their first collaborative project, they decided to take on the ubiquitous LED cube, trimming down the component count to nothing more than 64 LEDs, a protoboard, some wire, and a single Arduino.

Now, though, it shouldn’t be hard to control the RGB LED strips through an Arduino, a computer, or even an Android/iOS device with a small IR LED plugged into the headphone jack.
