Write Arduino code for a hall sensor and an accelerometer MPU-6050

This project is made for a skateboard activity monitor. Need to measure wheel speed and road slope. Hardware is ready, code needs to be done. The system consists of ATMEGA328P, a hall sensor (would appreciate if you could help me identify) MPU6050 Accelerometer and Bluetooth HM-10. Need to write a code for this system to deliver the y-axis and wheel speed values over bluetooth to the iOS app. There is a certain protocol that needs to be followed (check the attachments). The RPM Counter was made for a reed switch, you can change it accordingly. Open for suggestions regarding MPU6050.
