DIY Arduino Balancing Led strip

This time I will show you how to make balancing Led dot using WS2812 led strip and MPU6050 accelerometer and gyroscope module. This module 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. The code is taken from the Roel Arits blog with minor changes in hardware and software. Specifically I use Arduino Nano and LED strip with 37 LEDs. To update the position of a virtual object that is falling to the earth under the influence of gravity, we use the formula : y = y0 (V0 * t) (0.5 * a * t^2) y = travelled distance in meters y0 = start distance in meters v0 = start velocity in meters/second a = acceleration (gr
