DC MOTOR CONTROL WITH DIGITAL OUTPUTS

Task:

  1. Connect the DC motor to Digital Output D7 and D6.

  2. Write the program and check all the combinations of digital outputs; 00, 01, 10 and 11.

  3. For each combination of digital outputs mark the state of the motor (fulfill the [@tbl:motor_combo_ARB ]).R

| D7 | D6 | Motor rotation | |:–:|:–:|—————-| | 0 | 0 | | | 0 | 1 | | | 1 | 0 | | | 1 | 1 | | Table: All combinations of the states of motor’s connectors. {#tbl:motor_combo_ARB}

Questions:

  1. Try to stop the shaft of the DC motor for a short time and try to remember how difficult it is?
  2. Why does motors’ shaft not spinning if the digital output state are 1 and 1.

Wireing the DC motor to controller.

Summary

The motor's shaft is spinning according to the direction of the electric current trough the motor.
The torque is weak.
