Spacelady is an interactive, Arduino-controlled LED mural. Using a capacitive touch sensor, the Arduino triggers lights and sounds when copper tape pads are touched. To understand the functionality of this mural and to see it in action, watch the attached videos.
This interactive mural is very easy to build, requires just a few components, and is suitable for beginners.
NOTE: Regarding the Neopixels - read the Adafruit’s Neopixels uberguide. The guide recommends putting a 300-500Ω resistor between the Arduino and the data pin (purchase two resistors if you use more than one Neopixels strip; that's what I did). Depending upon the number of Neopixels you use for your project, you may also need an external power supply. Consult the uberguide.
