 Their robot moves so fast that it changes colour due to the Dopler Effect. By rapidly alternating between driving away from the viewer (Redshift) and driving toward the viewer (Blueshift), they can make the viewer see it in their traditional purple colour. - philso [more] |

Re: LED indicator lights
We started using outputs on the PCM for indicator led control this year. It was much easier, lighter, and cheaper than spikes or arduinos that we have used in the past.

Re: LED indicator lights
We didn't do it on our competition bot this year (weight problems) but we were going to use three DIOs on the rRIO MXP port to act as a 3-bit binary input to an arduino. From there, the Arduino drove a pair of WS2801 RGBLED strips, like those AndyMark used to sell.
