# cmd_dcmotor_release

Command to release pins which have setup for DC motor

### Calling Sequence

    cmd_dcmotor_release(h,motor_no)

### Parameters

h :

  Board number, reserved for future use. For this version, any number would do

motor_no :

  ID in which the motor has been connected

### Description

Arduino board does not deliver enough power, so it is necessary to use a H-bridge circuit/IC to control the motor. There are several types of H-bridge IC that do not all operate on the same principle. For example, the L298 requires the use of a PWM signal with current sense. The L293 uses two PWM to set the speed and direction. Ready-to-use Shields are also available.

Remember that the PWM is 8-bit (0 to 255). The input of the block could accept any value, but it would saturate at +- 255.

### Examples

    ok = open_serial(1,9,115200)
    cmd_dcmotor_setup(1,3,1,9,10)  // Setup DC motor of type 3 (L293), motor 1, pin 9 and 10
    cmd_dcmotor_run(1,1,255)
    sleep(1000)
    cmd_dcmotor_run(1,1,-255)
    sleep(1000)
    cmd_dcmotor_release(1,1)
    close_serial(1)
