Now, change the program so that the first LED shows red, the second green, and the third blue. We want all three to start with a light intensity of $0.$ After a second, all three change intensity to $50,$ then $100,150,200,250,$ and back to $0.$ Repeating forever.

$($VERY STRONG HINT: Do not use the pixel.setBrightness $()$ function. It is not intended for this purpose and will likely break and$/$or confuse you later.$)$

REMEMBER: Create a new project for each IoT exercise! When you do so$,$ reselect $$DeviceOS@$5\mathrm{.}8\mathrm{.}0$ and $$Photon $2/$ P$2,$ plus you$$ll need to reinstall the $$neopixel$$ library $($and potentially re$-$add the line #include $$neopixel$.$h$)$
