Now we will learn about the parameters parameters are the configuration value of a Node and we can 2
even change them during the real time operation as usual we will run the turtlesim node again 3
Ros2 param list so here we have all the available parameters and that the turtlesim 4
node has and we can like we can get the value and we can even set according to our desired value 5
so let's get the value of the background G parameters from the turtlesim node and uh 6
we can just copy it ros2 param get the node name turtlesim param name 7
and hit enter so it is an integer and its value is 86 and we can even set it like instead of 8
writing here get we will uh right here set and then the integer value that we want to input 9
like we will change it to like 120 it hit enter it has successfully set now if we want to get it 10
here it is set to 120 now so let's also set it to zero 11
you can see a significant change in the color and we will also set b 12
to zero it is going to turn black yeah it is finally black now and if we try to run 13
we can see the line more vibrant so this is how we can play with the parameters of a node 14
