4. APPLICATION WITH A RASPBERRY PI
Initially, connect the motor with your Raspberry Pi like shown in the
following connection diagram.
Since the motor is connected, you can transmit the following code
examples to your Raspberry Pi and test their functions.
In general applies:
The motor is controlled by the command
pwm.ChangeDutyCycle().
The
value between the brackets, can be among 2.5 and 12.5. If the value is
beneath a value of 7.5, the motor rotates in one direction. If the value is
above a value of 7.5, the motor rotates in the other direction. The further
away (or rather higher and lower) the value is from 7.5, depends on the
speed in which the servomotor is rotating.
If the value is set on 7.5, the motor stops.
You can modify and edit the code examples according to your wishes as a
matter of course.
Create now a data file with the following command:
sudo nano servo.py
Now enter the following code example into the editor. After that you can
save the file with the key combination of
STRG+O
and you confirm it with
Enter
. You can leave the editor with the key combination
STRG+X
.
