Kaleidoscope with Arduino and RGB LED strips
I present a new Arduino project: a Kaleidoscope (or something similar), with a list of the simplest materials.
You can see the result in the video. It can be used as decoration in a living room or as decoration for the baby's crib. The baby will be surprised ... Very relaxing if it accompanied with Chill out music .
Thanks to the advent of addressable LED strips, is extremely simple (and cheap) to create projects with multiple RGB LEDs.
These strips contain small RGB leds. Each led is accompanied by a WS2812 circuit capable of controlling an RGB LED with 256 levels for each color.
In the previous post (Christmas Tree shield for Arduino) I talk about the benefits of these chips
The strips have three connections +5 V, GND and data input (DI). Be careful because in the strips is indicated the data flow, the data must enter through DI and exit through DO (on the opposite side). To connect a strip piece with another, connect the DO of the first with the second DI.
The strips can be cut with simple scissors through the mark
The assembly is very simple, just a strip of LEDs 60 leds / m cut into 12 parts of 5 leds each, and mounted on a piece of PVC (forex). The strips are adhesive, so it is very simple.
A sheet of opal Plexiglas handles diffuse the light of the LEDs and enhance the effect.
The circuit is so simple it does not need schema ... just an output pin of the Arduino connected to the input of the strips (DI), and of course, the power supply (GND and 5V).
The code performs a series of symmetric random patterns to simulate the operation of a kaleidoscope.
