![]() The used stepper motor driver lets you control one bipolar stepper motor at up to approximately 1.5 A per phase continuously without a heat sink or forced air flow ( Datasheet ). By reading Euler angle I got problems with Gimbal lock. This reduces the load for the Arduino.īecause of the orientation of my board, I used yaw/pitch/roll angles (in degrees) calculated from the quaternions coming from the FIFO. I used Digital Motion Processing with the MPU-6050 sensor, to do fast calculations directly on the chip. The sensor uses the I2C -bus to interface with the Arduino. Therefor it captures the x, y, and z channel at the same time. It is very accurate, as it contains 16-bits analog to digital conversion hardware for each channel. The MPU-6050 sensor contains a MEMS accelerometer and a MEMS gyro in a single chip. simple position sensing by counting PWM signal. ![]()
