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 LEDstrip, so when the LEDstrip 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 t2) y travelled distance in meters y0 start distance in meters v0 start velocity in meters, second a acceleration (gr
