Notice the Motors subsystem. Thank you for your continued support. If channel A pulse output leads channel B then the motor is rotating clockwise and if channel B leads channel A the motor is rotating anti-clockwise. The code cannot miss pulses, if it does, you have lost position. The L298 Dubai H Bridge is base on l298 Chip manufacture by ST Semiconductor. When motor turns on and with a very slow speed the pules are not constants, seems the arduino don have speed enought to get the pules in right time (or the connection between the pc and arduino). You can use PID. // -- Makes use of the L293 motor driver; may easily be adapted to another driver // -- Motor pwm'ing implemented by direct control of the ATmega Timer2 // -- Closed-loop feedback via encoder wheel on the DC motor. Your code for Arduino + Encoder was very much helpful, but Please check it once, Note the initial value and rotate the shaft of encoder left to right 360 degree. For both types of encoder, the position measurement can be either incremental or absolute. The motor breaks by pushing the encoder key or setting the encoder in position 0. The Radio Artisan Arduino Rotator Controller interfaces a computer to a rotator or a commercial rotator controller, emulating the Yaesu GS-232A/B and Easycom protocols which are supported by a myriad of logging, contest, and control programs. Controlling DC Motors. Interested in encoder? Explore 11 projects tagged with 'encoder'. A DC motor was used to attempt to minimize noise in the system.
