hi there... My plan is want to use the colour sensor that programmed in arduino...then send the message to ROS.Then i can use it on turtlebot teleop, and the way is it will change the speed automatically by detecting the colour. I want do like traffic light, when the sensor detect green colour it will go fast, and when it detect yellow it will go slow..and when the sensor detect the red colour it will stop the telop. 1) is that possible? 2) What is the way that I can make this work done? 3) Is there any changing at node? topic?
