LED's How do you make 150 x individually addressed LED's flash? Answered

Hi,

I am trying to get a project started that requires up to 150 x individually addressable LED's. Each LED needs to be programmed to flash individually. Ideally the project would be controlled by an Arduino or similar and would be battery powered as it needs to be portable. The whole system needs to be operated with a simple On/Off switch.

The flashing sequence for each LED is critical so if a piece of software is available to easily set up and control the flashing sequences, then that would be a big bonus.

The LED's will be mounted in pre-drilled holes on a large sheet of plywood. Each sheet would then need to be repeated to build up an array of sheets.

Any help would be much appreciated.

The LEDs your looking for are likely WS2811 or WS2812.

If your wanting to just flip a switch and have it start its sequence, an arduino running a program with fastLED or neopixel library will be able to handle the 150 lights without an issue.
Where this is going to get more complicated is the battery. I usually figure an average use of 1.5 amps / 50 lights, so your talking roughly 4,500 mAh per hour you plan on running this.

There are programable LED matrix display available....
Also neopixels come to mind here.
In old school tech you need a lot of transistors and matrix IC's just to make it possible to address the single LED's.
