The loop constantly checks if the gyro data is equal to the user input & sidereal time data. The default is 0,0. If there is a change and the equality breaks the master module send a command to the slave module. If the user value is higher than the gyro value a signal is sent through cw the motor turns clockwise. + If the user value is less than the gyro value a signal is sent through ccw the motor turns counter clockwise + If the user value is equal to the gyro value a signal is sent through stahp and the motor stops same for cw2,ccw2,stahp2.
