3. None

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

9. None

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); }

18. MY SOFTWARE https://github.com/gijzelaerr/nye-outfit

19. None

20. THE PROBLEMS fragile hardware change requires software
