1. DIY LED COSTUME Gijs Molenaar - KAT-O - Cape Town - 23 May 2016

4. WHY?
5. - me “Why not.”
6. Play with embedded hardware Prosuming @ AfrikaBurn
7. THE INGREDIENTS Digital RGB LED strip WS2812B - 60 LED - 2.5 M ( € 50 ) 8000 mAh powerbank ( € 50 ) Arduino Uno ( € 25 ) Suit, custom made by friend ( € can’t remember ) Money belt ( € 2,50 )
8. RGB LED STRIP
10. each cell containers 3 LEDS Red, Green Blue 0-255 brightness per led 16M different colors Cascading port transmission signal by single line Number of LEDS depends on update freq
11. PRACTICAL LED LEDs are very bright Used 25% brightness
12. ‘SCHEMA’ 3 wire connections Flexible cat-5 for connecting strips
13. POWERBANK € 50 Off the shelf could run for 2 days still use it often
14. ARDUINO UNO Real time 14 IO pins 2 KB mem
15. PRACTICAL ARDUINO very easy to do runs out of memory quickly (my poor embedded programming)
16. THE SOFTWARE using FastLED http://fastled.io/ Array based, no worries about timing
17. EXAMPLE #include "FastLED.h" CRGB leds[1]; void setup() { FastLED.addLeds<NEOPIXEL, 6>(leds, 1); } void loop() { leds[0] = CRGB::White; FastLED.show(); delay(30); leds[0] = CRGB::Black; FastLED.show(); delay(30); }
