Nybble doesn't like obstacles !

Good start!

One hint, you can change the 1s after #define in IRremoe.h to 0 as below, then you will save about 10% of the programming space for more logic codes.

// Supported IR protocols
// Each protocol you include costs memory and, during decode, costs time
// Disable (set to 0) all the protocols you do not need/want!

Thank you very much for your advise ! It will help me for sure.

Hi Lilie,

Congratulations on creating your first course! I'm assuming you're using the ultrasonic sensor for obstacle detection?

Is your initial course based around only instantiating the ultrasonic sensor to detect obstacles, or will you be extending the code to allow Nybble to make directional decisions as well?

Looking forward to seeing more of your upcoming your course material!

Hi @FuzzyFoyz ,

Thanks for your kind comment !

As this course is one of the first one for the kids, it has to stay quite "simple" so yes I am using the ultrasonic sensor. I have a lot of projects for the next courses, including a (simple) obstacle avoidance algorithm.

I am currently working on computer vision algorithms, and on adding some LCD screens on MiniCat. I am looking forward to showing you the results ! Best regards :)

hello, fantastic job, I have put your code in my diy "nyacat" and apart from that the code occupies 107% of memory that is solved with the Rongzhong Li trick, when the program is run it starts fine but on the serial monitor they appear infinite 0 and does nothing else, it is my problem or the code, Thanks

Hey, thanks for your message, I'm sorry I haven't seen it before ! That's weird... I have to admit I don't know what your problem is, I don't have this error with my Nybble. Could you send me more details and screenshots of the error(s) ? Maybe I will be able to help you. Have a nice day 🙂
