And then put my code in your trinket, is programmed to turn the LED's in blue with a small animation. Now download the great FastLED library from GitHub and install it. You now know how to load programs to the Trinket with Arduino and the basics, probably you have done a Blinky demo :) When you are ready come back to the action. Luckily adafruit has a great tutorial right here. Okay, first of all you will need to learn how to use the Trinket. Note: I used the plastic bag that came with the velostat sheet to protect the sensor from humidity, just slip it in :) Is everything is okey you now have a fully functional stepping sensor!!!.Also be careful of letting a small space without tape or make a tiny hole in both aluminum and cardboard to allow air escaping without making damage to the sensor. Then use a thin cardboard from protect the aluminum foil from ripping, this sheets must be the same size as the entire sensor.Solder wires to the attached copper tape and use some kapton tape to protect the connection.Use some copper tapper to create electrical contacts, one goes in the bottom aluminum foil and the other one in the top.Also let a small space free of tape for the wiring. Then use some electrical tape to join the 3 sheets, remember that in the middle goes the velostat sheet.Cut two aluminum foil sheets a bit smaller than the velostat sheet.Please use the photos as reference and follow this steps: This is probably the longest part of this tutorial, but it's easy. But consider a proper power supply for your setup, remember that most rgb strips can need as much as 60 mA per LED.
In my setup I used 50 LED SM16716 modules, feel free to use as much leds as you want and any model the code supports. This is up to you, my code has a lot of options available.
