Skywalker Lightsaber
Not as clumsy or random as a blaster. An elegant weapon from a more civilized age.
Don't point this directly at your face when handling! Handle with caution and care.
Skywalker Lightsaber | Adafruit Trinket M0 - controlling the onboard dotstar LED via Arduino IDE
2018-01-04 11:08:16
Since I couldn't find how to control it, here's my code how I did it. They probably focus on their python stuff more than on the Arduino IDE, which makes sense and all in all the Trinket still works with the Arduino IDE, so hurray :) You need to install the Adafruit_DotStar library, best done with the library installer. I had to change the datapin and clockpin, easy to find on the pinout site (https://learn.adafruit.com/adafruit-trinket-m0-circuitpython-arduino/pinouts. The other change I had to make was the configuration definition to BGR, RGB backwards. Now that I was able to do that, I found this https://forums.adafruit.com/viewtopic.php?f=25&t=124501&sid=21195cd2275abc7ba8a32912d47cff6f :D
#include <Adafruit_DotStar.h>

#define NUMPIXELS 1
#define DATAPIN 7
#define CLOCKPIN 8
Adafruit_DotStar strip = Adafruit_DotStar(
NUMPIXELS, DATAPIN, CLOCKPIN, DOTSTAR_BGR);
void setup() {
strip.begin();
strip.show();
}
void loop() {
strip.setPixelColor(0, 0xFF0000);
strip.show();
delay(1000);
strip.setPixelColor(0, 0x00FF00);
strip.show();
delay(1000);

Skywalker Lightsaber | more standards and modules

I was inspired by @deshipu to get an adafruit trinket M0 and redo the lightsaber with it, since the atsamd21 being used has a DAC on board and enough pins left to control some neopixels, check a button and grep stuff over I2C from the accelerometer. Just playing around with arduino and analog write I can say that it sounds so much better already.
There will be a connector involved for the neopixels and I want to make everything fit the acrylic pipe first, then redesign the 3D printed parts where needed.

Skywalker Lightsaber | APA106 vs. WS2812B

So it turns out that they are almost the same protocol... Red and Green are switched. But that is fixable :)

I haven't checked the MPU6050 yet, but until I do I have to choose a color. Maybe I'll go with purple. Or rainbow.

So I wanted to present my lightsaber and quickly plugged in the power supply but forgot to set the voltage first. Muahahah. Damn.
