00:00:06,000  -->  00:00:13,860
Now we will learn about the parameters parameters are the
configuration value of a Node and we can

2

00:00:13,860  -->  00:00:20,400
even change them during the real time operation
as usual we will run the turtlesim node again

3

00:00:25,440  -->  00:00:36,540
Ros2 param list so here we have all the
available parameters and that the turtlesim

4

00:00:36,540  -->  00:00:46,860
 node has and we can like we can get the value
and we can even set according to our desired value

5

00:00:46,860  -->  00:00:57,240
so let's get the value of the background G
parameters from the turtlesim node and uh

6

00:00:58,320  -->  00:01:08,400
we can just copy it ros2 param get the node name turtlesim param name

7

00:01:09,000  -->  00:01:19,320
and hit enter so it is an integer and its value
is 86 and we can even set it like instead of

8

00:01:19,320  -->  00:01:28,620
writing here get we will uh right here set and
then the integer value that we want to input

9

00:01:28,620  -->  00:01:38,940
like we will change it to like 120 it hit enter
it has successfully set now if we want to get it

10

00:01:40,140  -->  00:01:46,860
here it is set to 120 now
so let's also set it to zero

11

00:01:49,020  -->  00:01:54,720
you can see a significant change in
the color and we will also set b

12

00:01:55,920  -->  00:02:08,760
to zero it is going to turn black
yeah it is finally black now and if we try to run

13

00:02:09,600  -->  00:02:20,040
we can see the line more vibrant so this is
how we can play with the parameters of a node

14

00:02:22,920  -->  00:02:23,640
