We want to be able to wire a set of led for the robot this years robot anyone who knows a good brand and how to wire them up also can we use a usb and plug it in to the reo
I highly recommend the REV Blinkin if you want to control your LED’s from the rio.

See Addressable LEDs — FIRST Robotics Competition documentation
You can find WS2812B type LEDs for cheap at many places, including Amazon etc.

We are using 1m of these directly off the Rio. Technically over the power limit, but managing color and brightness can bring it into spec.

Hey Great idea this is our teams first ever time using LED and we use purple yellow red and blue. red and blue depending on our alliance and purple and yellow depending on whether we want a cone or a cube.
we use CTRE cannifer.
Is there anything else because that controller is out of stock
We are using 12v Addressable LEDs running directly off the PDH for power and the roborio for data signal. So far so good. They do dim when we brown out but it’s work the simplicity of wiring.

Do you have a link for them

Note that this LED strip has 3 LEDs equal to 1 address.
how does the canifyer work for ya? I think we’re considering using it (mostly because its the only easier led driver in stock)
I’m not a programmer but our programming team is very new and they figured it out no problem plugs right into it he can chain and grabs power from the PDP took about 20 minutes all set and done to get it functioning as we like it
purple, orange, and yellow LEDs…
like these?
We used individually addressable, 5v, WS2812B LEDs off Amazon and plugged them directly into the rio’s PWM port.
Using WPILib’s documentation for WS2812Bs, we set HSV values for an aesthetic orange ripple mode, and then purple and yellow for cube/cone pickup, respectively, to signal the human player. We also just added a mode that flashes the lights when the Limelight says we’re lined up with the grid.
Let me know if you have any questions!

what do you use as a diffuser for the lights?
We had a student donate a bunch of rails and diffusers for light strips, just standard thin strips of white flexible plastic. We mounted them with VHB tape. Ours arent diffused very well atm because the plastic is mounted too close to the lights, but we’re going to move them further for a nicer effect. You can buy diffusers pretty cheap or even 3d print your own.
