# MPU6050_Accelerometer_Gyro
Three axis and 6 Degrees of Freedom - and cheap too

A cheap MPU6050 Accelerometer and Gyro can determine its orientation very well, and could be useful for quadcopters, drones or other model aeroplanes, as well as simpler experiments such as a digital spirit level like the one I create here in my demo.

Whilst there is an excellent library by Jeff Rowberg that allows all the functionality possible with this device, the demo sketch doesn't use any, and relies on the raw data being manipulated to provide a stable and useful x-axis reading (in degrees) that could easily be extended to include the y- and z-axes too.

Just to build on previous sketches I'm using some neopixels here to provide the visual indication of how level the x-axis is, and with some jiggery pokery have managed to to get it to show the centre led when balanced with the leds to the left (or right) illuminated depending on how far off-balance it is.

I'll be interested whether anyone kind think of any practical uses over and above stabilising a quadcopter or making a spirit level.
