DESCRIPTION
In this project, we will build a Digital Protractor using MPU6050 and Arduino. Here a servo motor is used to display the angle on a protractor image. The Servo motor shaft will rotate on a protractor image to indicate the angle which is also displayed on a 16xLCD display.

WORKING AND OUTPUT
Welcome to the Arduino-based project in which we are Making a digital protractor using the servo Motor and MPU6050 Accelerometer module. In the code Formula to calculate the x value in degrees (0 to 360) is given below. Here we convert only x because the servo motor rotation is based on x value movement.
x= RAD_TO_DEG * (atan2(-yAng, -zAng)+PI);
write the angle value to rotate the servo on the protractor image and Print those values on the 16x2 LCD. So, this is how MPU6050 with Arduino can be used to measure the angle.
Here servo motor is connected with Arduino and its shaft is projected on the protractor image indicating the angle of the inclined MPU6050
According to the orientation of the MPU 6050 module, we will see the inclination angle on the LCD as well servo motor along with a protractor image.
Try to move at different angles and check the degree rotation on LCD and Protractor.
