arduino pro mini rgb led test

/* * Code for cross-fading 3 LEDs, red, green and blue (RGB) * To create fades, you need to do two things: * 1. Describe the colors you want to be displayed * 2. List the order you want them to fade in * * DESCRIBING A COLOR: * A color is just an array of three percentages, 0-100, * controlling the red, green and blue LEDs * * Red is the red LED at full, blue and green off * int red = { 100, 0, 0 } * Dim white is all three LEDs at 30% * int dimWhite = {30, 30, 30} * etc. * * Some common colors are provided below, or make your own * * LISTING THE ORDER: * In the main part of the program, you need to list the order * you want to colors to appear in, e.g. * crossFade(red); * crossFade(green); * crossFade(blue); * * Those colors will appear in that order, fading out of * one color and into the next * * In addition, there are 5 optional settings you can adjust: * 1. The initial color is set to black (so the first color fades in), but * you can set the initial color to be any other color * 2. The internal loop runs for 1020 interations; the 'wait' variable * sets the approximate duration of a single crossfade. In theory, * a 'wait' of 10 ms should make a crossFade of ~10 seconds. In * practice, the other functions the code is performing slow this * down to ~11 seconds on my board. YMMV. * 3. If 'repeat' is set to 0, the program will loop indefinitely. * if it is set to a number, it will loop that number of times, * then stop on the last color in the sequence. (Set 'return' to 1, * and make the last color black if you want it to fade out at the end.) * 4. There is an optional 'hold' variable, which pasues the * program for 'hold' milliseconds when a color is complete, * but before the next color starts. * 5. Set the DEBUG flag to 1 if you want debugging output to be * sent to the serial monitor. * * The internals of the program aren't complicated, but they * are a little fussy -- the inner workings are explained * below the main loop. * * April 2007, Clay Shirky <clay.shirky@nyu.edu> */ // Output int redPin = 3; // Red LED, connected to digital pin 9 int grnPin = 5; // Green LED, connected to digital pin 10 int bluPin = 6; // Blue LED, connected to digital pin 11 // Color arrays int black[3] = { 0, 0, 0 }; int white[3] = { 100, 100, 100 }; int red[3] = { 100, 0, 0 }; int green[3] = { 0, 100, 0 }; int blue[3] = { 0, 0, 100 }; int yellow[3] = { 40, 95, 0 }; int dimWhite[3] = { 30, 30, 30 }; // etc. // Set initial color int redVal = black[0]; int grnVal = black[1]; int bluVal = black[2]; int wait = 10; // 10ms internal crossFade delay; increase for slower fades int hold = 0; // Optional hold when a color is complete, before the next crossFade int DEBUG = 1; // DEBUG counter; if set to 1, will write values back via serial int loopCount = 60; // How often should DEBUG report? int repeat = 3; // How many times should we loop before stopping?
