NeoPixel Digital RGB LED Strip

NeoPixel Digital RGB LED Strip, has 144 LED per metre and is water resistant. You can program it to have really cool LED sequences. You can create an interactive LED display using an Arduino Uno, a potentiometer and an accelerometer. The 144 LEDs can be programmed indicidually. this DIY gives you the source code of 5 sequences, but you can try many many more. You can the hue and brightness. Change direction and speed using an accelerometer and play with sequences like the comet effect, bounce effect etc. You can see the crazy things it can do, in the video, below.

To get started, get the ingredients in place. You can get the complete list, in the source code, given at the end. You will need a power supply as each LED draws around 60 milliamps of power. Excessive voltage can destroy your strip. So be careful! You can always increase the length of the strip, by adding another one to it, but you’ll need more power, in that case.

Start with the software and program the Arduino microcontroller. You can get all the codes from the source link, again. Once, you’re done, make the connections.
