Waterproof NeoPixel Digital RGB LED Strip - White 60 LEDs [1 Meter] - (AD2203)

Description:

First, the higher density means much higher power usage over a certain distance - 18 watts maximum (~3.5 Amps @ 5V) per meter instead of 9.6 watts maximum (~2 Amps @ 5V). For maximum amperage, it is assumed that all LEDs are at maximum white color intensity, generally the actual current for the design at its maximum color is approximately 1/3 to 1/2 of the maximum current. A good power supply, for example, 5V 4A to 10A, is key.

Second, to achieve high density, the driver chip is inside the LED, which means the chip only uses a single pin for input and a single output pin. The protocol used is very time-specific and can only be controlled by high-precision microcontrollers. There are code examples to control it with the Arduino Uno ATMega28/8MHz-16MHz microcontroller, and with a little effort, it can be used with the Raspberry Pi, except with the Basic Stamp, Netduino, or any other microprocessor slower than 8MHz.

Third, just because it has all those pixels doesn't mean you have the RAM for it. The entire strip must be stored in memory, and we have found many Arduino Uno projects that only have about 1500 bytes of RAM available, enough to control about 500 LED pixels. If you want to control the entire strip and have some other libraries included, use a Mega.

These LED strips are even more fun. There are 60 RGB LEDs per meter, and you can control each LED individually! Yes, that's right, this is a digitally addressable LED strip type. You can set the color of each LED component (red, green, and blue) with 8-bit PWM precision (i.e., 24 bits per pixel). The LEDs are controlled by shift registers that are daisy-chained so you can shorten or lengthen the strip. Only 1 digital output pin is required to send data. The PWM is built into each chip of each LED, so once the color is set you can stop sending the data frame to the strip and the PWM will continue on all LEDs.
