Hello! I want to make a ping pong ball tracker (that detects a ping pong ball) and then display a color on the right side of the screen corresponding to where the ping pong ball is. What I mean is, if the ping-pong ball is on the right side of the screen, it'll be one color. If it's straight ahead, it'll be a different color. If it's on the left side, it'll be a different color. This is a way to communicate with my VEX IQ kit (a robotics kit, similar to Lego Mindstorms). I could use a Bluetooth radio, but I don't have one, and I'm not in the market for one. Also, I will be using normal orange ping pong balls. I will also be using my Samsung Galaxy S8 as the Android phone. I'm a total NOOB at OpenCV. I have some experience with Java though, so if this could be coded in Java, it would really help. So far, nothing has worked for me. Again, if you can tell me how to do this, it would really help (maybe even include some code since I'm a noob). Thanks!
