Rgb Light Bar

prusaprinters

<p>This is a light bar (rgb). It is designed for easy printing and easy assembly. It is a decoration for a desk or as a relaxation lamp. The light bar uses the Arduino nano. You can load your chosen code into this chip, such as: rainbow, fire flames, and many more.</p> <p>°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°<br/> RAINBOW CODE FOR ARDUINO NANO HERE:</p> <h3>include &lt;Adafruit_NeoPixel.h&gt;</h3> <h3>include &lt;avr/power.h&gt;</h3> <h3>define PIN 6</h3> <p>Adafruit_NeoPixel strip = Adafruit_NeoPixel(20, PIN, NEO_GRB + NEO_KHZ800);<br/> void setup() {<br/> // This is for Trinket 5V 16MHz, you can remove these three lines if you are not using a Trinket</p> <h3>if defined (<strong>AVR_ATtiny85</strong>)</h3> <p>if (F_CPU == 16000000) clock_prescale_set(clock_div_1);</p> <h3>endif</h3> <p>// End of trinket special code<br/> strip.begin();<br/> strip.show(); // Initialize all pixels to 'off'<br/> }<br/> void loop() {<br/> rainbowCycle(10);<br/> }<br/> // Fill the dots one after the other with a color<br/> void colorWipe(uint32_t c, uint8_t wait) {<br/> for(uint16_t i=0; i&lt;strip.numPixels(); i++) {<br/> strip.setPixelColor(i, c);<br/> strip.show();<br/> delay(wait);<br/> }<br/> }<br/> void rainbow(uint8_t wait) {<br/> uint16_t i, j;<br/> for(j=0; j&lt;256; j++) {<br/> for(i=0; i&lt;strip.numPixels(); i++) {<br/> strip.setPixelColor(i, Wheel((i+j) &amp; 255));<br/> }<br/> strip.show();<br/> delay(wait);<br/> }<br/> }<br/> // Slightly different, this makes the rainbow equally distributed throughout<br/> void rainbowCycle(uint8_t wait) {<br/> uint16_t i, j;<br/> for(j=0; j&lt;256<em>5; j++) { // 5 cycles of all colors on wheel<br/> for(i=0; i&lt; strip.numPixels(); i++) {<br/> strip.setPixelColor(i, Wheel(((i </em> 256 / strip.numPixels()) + j) &amp; 255));<br/> }<br/> strip.show();<br/> delay(wait);<br/> }<br/> }<br/> //Theatre-style crawling lights.<br/> void theaterChase(uint32_t c, uint8_t wait) {<br/> for (int j=0; j&lt;10; j++) { //do 10 cycles of chasing<br/> for (int q=0; q &lt; 3; q++) {<br/> for (int i=0; i &lt; strip.numPixels(); i=i+3) {<br/> strip.setPixelColor(i+q, c); //turn every third pixel on<br/> }<br/> strip.show();<br/> delay(wait);<br/> for (int i=0; i &lt; strip.numPixels(); i=i+3) {<br/> strip.setPixelColor(i+q, 0); //turn every third pixel off<br/> }<br/> }<br/> }<br/> }<br/> //Theatre-style crawling lights with rainbow effect<br/> void theaterChaseRainbow(uint8_t wait) {<br/> for (int j=0; j &lt; 256; j++) { // cycle all 256 colors in the wheel<br/> for (int q=0; q &lt; 3; q++) {<br/> for (int i=0; i &lt; strip.numPixels(); i=i+3) {<br/> strip.setPixelColor(i+q, Wheel( (i+j) % 255)); //turn every third pixel on<br/> }<br/> strip.show();<br/> delay(wait);<br/> for (int i=0; i &lt; strip.numPixels(); i=i+3) {<br/> strip.setPixelColor(i+q, 0); //turn every third pixel off<br/> }<br/> }<br/> }<br/> }<br/> // Input a value 0 to 255 to get a color value.<br/> // The colours are a transition r - g - b - back to r.<br/> uint32_t Wheel(byte WheelPos) {<br/> WheelPos = 255 - WheelPos;<br/> if(WheelPos &lt; 85) {<br/> return strip.Color(255 - WheelPos <em> 3, 0, WheelPos </em> 3);<br/> } else if(WheelPos &lt; 170) {<br/> WheelPos -= 85;<br/> return strip.Color(0, WheelPos <em> 3, 255 - WheelPos </em> 3);<br/> } else {<br/> WheelPos -= 170;<br/> return strip.Color(WheelPos <em> 3, 255 - WheelPos </em> 3, 0);<br/> }<br/> }</p>
