This project has no practical use at all, but was initiated as an exercise in implementing physics formulas related to gravity in C-code on an Arduino. To make things visible, a neopixel LED-strip with 74 LEDs was used. The effect of the gravitational acceleration on an object is demonstrated by using a MPU-6050accelerometer and gyroscope chip. This chip is physically attached to the LED-strip, so when the LED-strip is held at a certain angle, the chip measures the angle of the LED strip and the Arduino uses this information to update the position of a virtual object as if it was a ball that is balanced on a beam and rolls from one side to the other if the beam is held at an angle. The position of the virtual object is indicated on the LED strip as a single LED that is illuminated.
