LittleBits/Matrix Color Rotator Code for Twilio Signal HackPack

I made my twitter handle scroll across the screen, changing colors as it goes – pretty simple effect, but here’s the Arduino code:

#include <Adafruit_NeoPixel.h>
#include <Adafruit_GFX.h>
#include <Adafruit_NeoMatrix.h>

#define PIN 1

Adafruit_NeoMatrix matrix = Adafruit_NeoMatrix(8, 8, PIN,
NEO_MATRIX_TOP + NEO_MATRIX_RIGHT +
NEO_MATRIX_COLUMNS + NEO_MATRIX_PROGRESSIVE,
NEO_GRB + NEO_KHZ800);

void setup() {
// put your setup code here, to run once:
matrix.begin();
matrix.setTextWrap(false);
matrix.setBrightness(30);
matrix.setTextColor( matrix.Color(0, 0, 255) );

}

int x = matrix.width();

int colorRotator = 0;

void loop() {
// put your main code here, to run repeatedly:
matrix.fillScreen(0);
matrix.setCursor(x, 0);
matrix.print(F("@jefflinwood"));
if(--x < -70) {
x = matrix.width();
colorRotator++;
}
if (colorRotator > 3) {
colorRotator = 0;
}
if (colorRotator % 3 == 0) {
matrix.setTextColor( matrix.Color(0, 0, 255) );
} else if (colorRotator % 3 == 1) {
matrix.setTextColor( matrix.Color(0, 255, 0) );
} else {
matrix.setTextColor( matrix.Color(255, 0, 0) );
}
matrix.show();
delay(100);
}

Quick Installation Guide for Twilio Plugin for PhoneGap

I’ll be speaking at Twilio’s Signal Conference later today about the Twilio Client Plugin for PhoneGap. Here’s a quick getting started guide (as a PDF) for running the Twilio Client inside of a PhoneGap mobile App.

Built In Austin and BurntX run articles about UT Apps Demo Day

UT Apps Demo day is tomorrow, but the students’ mobile app demos have already gotten some press!

First up is Built in Austin, with an article titled 6 apps to debut at UT Austin App Demo Day.

Next is burnt x, with Six Apps Made For UT Students By UT Students.

I’m really excited for tomorrow’s UT Apps Demo Day – I’ve seen all of these students form groups, work through issues, and go from concept to working app all in one semester (on top of all their other classes).
