WEEK ASSIGNMENT:

Output devices

Add an output device to a micro-controller board you've designed and program it to do something

 

 

 

 

 

 

For this week activity we need to add a output to a micro-controller board.

We use some digital serial LED's : WS2811

We use the attiny44A micro-controller Board made in activity six, based in Fab Academy Hello-World board:

 

 

 

 

 

 

 

To connect the WS2811 serial LED's, we use the Ground, 5V an Data Pin.

 

 

 

 

 

 

 

Color Test

 

Using the Fast_Led Library you can change the color of each single LED using a RGB color code or using the precharged color names:

 

 

 

 

 

 

 

Code:

#include "FastLED.h"

#define NUM_LEDS 22

#define DATA_PIN 0

CRGB leds[NUM_LEDS];

int x=20;

 

void setup() {

    pinMode(DATA_PIN, OUTPUT);

  FastLED.addLeds<WS2811, DATA_PIN, RGB>(leds, NUM_LEDS);

}

void loop() {

leds[0] = CRGB::Black;

leds[1] = CRGB::Red;

leds[2] = CRGB::Blue;

leds[3] = CRGB::Green;

leds[4] = CRGB::Purple;

leds[5] = CRGB::Yellow;

leds[6] = CRGB::Cyan;

leds[7] = CRGB::Coral;

leds[8] = CRGB::DarkBlue;

leds[9] = CRGB::Orange;

leds[10] = CRGB::Pink;

leds[11] = CRGB::Gold;

leds[12] = CRGB::FloralWhite;

leds[13] = CRGB::Sienna;

leds[14] = CRGB::Maroon;

leds[15] = CRGB::MediumOrchid;

                leds[16].r = 0;

                leds[16].g = 0;

                leds[16].b = 255;

 

                leds[17].r = 0;

                leds[17].g = 255;

                leds[17].b = 0;

 

                leds[18].r = 255;

                leds[18].g = 0;

                leds[18].b = 0;

 

                leds[19].r = 255;

                leds[19].g = 255;

                leds[19].b = 0;

 

                leds[20].r = 255;

                leds[20].g = 0;

                leds[20].b = 255;

 

                leds[21].r = 0;

                leds[21].g = 255;

                leds[21].b = 255;

 

FastLED.show();

}
