My sons Cub Scout pack has a Pinewood Derby 'open' race for family members, so I decided to enter this year. My initial goal was to 'add a few lights' to a car, but I had no set idea of what I was going to do.....but, a few weeks later, after discovering the TinyScreen+ from TinyCircuits, Neopixels from Adafruit and LSM303 Accelerometer/Compass from Adafruit, (and with much research, learning and experimentation), I present "The Light Fantastic"! (The flicker on the TinyScreen+ display is an artifact of this video - in real life, it's rock solid)
The car plays through a sequence of Neopixel patterns with OLED bitmap displays, animations and text marquees, and can detect being tilted forward to switch to a "race mode" RPM-style gauge display. A menu can be accessed by pressing one of the microswitches, and the mouse pointer/settings/compass display accessible from there are controlled by tilting/rotating the car. Obligatory TinyScreen game Flappy Birdz is included and also playable on the car! The menu, along with selections of brightness configuration, displaying a compass and playing Flappy Birdz, are shown at the end of the video. Enjoy!
