So here’s something I should have posted quite awhile ago. This is a ‘breakout board’ I made for controlling LED strips with Arduino over bluetooth or USB.

PCB

It’s a little PCB for an Arduino nano, bluetooth chip, and (3) 4-pin terminal blocks with PWR-GND-SN-CK, and a 2-pin block for PWR-GND input. It can be used with 3 or 4 pin LED strips, or anything really, servos, sensors, whatever. I designed the PCB using Fritzing and had it printed through OSH Park. If you’re interested in one let me know via the funkboxing contact form. I’ll offer just the bare board or a pre-soldered and tested version with a nano, bluetooth chip, and terminal blocks, or any variation thereof. I can’t really come up with a price that makes sense, so if you tell me what you’re planning on using it for and I think it’s cool I’ll probably give it to you pretty much at-cost.

And here’s an LED array I made with it.

Array

It uses (64) WS2811 LED’s in an 8×8 array, an Arduino Nano, bluetooth chip, and a USB battery pack. It’s a double-decker sandwich of (3) 1/2″ thick acrylic plates so the whole rig is excessively large and heavy, but I kind of meant for it to be that way. I wanted something as a little testbed for 2D effects, of which I’ve only made a few so far. I’ll post the 2D array code at some point, but I should clean it up and make sure it works with the newest FastSPI library first.

  1. Hi
    Im not a programmer but have been interested in bt led control for a while. I saw your android app n such. Have you optimized your code for fastled and ws2812? The 4 wire led strips are just too expensive
