I'm starting to "play" with my Ringo; I want to share this simple sketch of light effects
Finally I've copied part of Behavior 5 (color wheel) to change animation's colors.
Is very elemental... but in a dark room Ringo makes a nice effect, specially "moving light"
To test, simply open Ringo_Base_Sketch_Rev06_01, or download from PlumGeek GitHub here
and replace all code in main sketch ("Ringo_base_sketch...") for next code:
Code: Select all
/*
First steps with Leds
Program based on Plumggek guide examples
AngoLito - May 2016 - Luanda
Efects:
- Moving light
- Flash eyes
- Dimmer down face Led
Used Behavior 5 sketch (color Wheel) to change color trought Gyro sensor
