Forgot to show the picture! But I think I found OpenCat.h hidden in the drop down! Reloaded, calibrated, Nybble happy for now. Thanks for your help along the way. “Taja ha how”

Unfortunately I don’t see a display OpenCat.h when I double click Write instinct.ino This is what I get. If I double click OpenCat.h I get the same thing, no tab for OpenCat.h. So we have to figure out how to get the OpenCat.h tab to come up. I know it’s something I’m doing wrong. Should I be using a PC and not a Mac?

Thanks for answering, but I can’t get OpenCat h to open under Arduino, so it can’t be edited, see my screen shot. I’m doing something wrong here!

You are totally brilliant! I think this is going to work…. Thanks!

I'm getting a little lost! In the software that is. I am ok testing the RGB Ultrasonic module and the buzzer. The other test modules won't upload to Nyboard, I get messages like a file is missing. After quite a few attempts at uploading write instinct.ino I did get it to the board and I did answer yes to the questions in the serial monitor, but I never heard or saw a servo move. I also couldn't find where I have to change the * Nyboard V1_1. Now when I try to upload write instinct to try to calibrate I can't get it to compile. All I get is a message that opencat.h doesn't exist. So I must be doing something wrong! Can anyone suggest what that might be?

Many thanks for your prompt reply! If I would have looked more closely at your videos I would have seen my mistake in mounting the board on top, rather than under its carrier. I must tell you I haven’t had this much fun and stimulation in a project since I retired from eye surgery! Now if I can just master coding! Barry
