Hi Hans, That should not be a problem. Why are you saying that you cannot do that?

In my old way. I would like to adapt it now with the HCRS04 lib. I use the 16F877a and I tried to convert the sample for this. Of course I can't do that again. Is it too much to ask to adapt the sample of 16F1827 for the 16F877a?

The one I made has a camera on board so I can look under the furniture to see if there is dust. The speed is therefore much lower and I could do everything with one 16F648a. I did use a ready-made motor driver set. This is of course much more professional. Very good. greetings Hans Op zaterdag 5 april 2025 om 19:12:36 UTC+2 schreef Rob CJ: Hi Vasile, I remember that car. I had it as a toy. It worked completely mechanical. When it reached the end of the table it turned. Could also buld it in this car 🙂.

It had no electronics whatsoever except a bistable relay and two front and two rear contacts. Much more elaborated is yours... Great.

I am using the JAL HC-SR04 library for measuring the distance but since the library is made to support only one module, I am using an Analog Multiplexer IC (74HC4052) to multiplex the three sensors. For a video, see: https://youtu.be/kwYxd5GjtCw I also posted the project on Instructables: https://www.instructables.com/Self-Driving-Robot-Wagon/ Kind regard, Rob Op zondag 9 februari 2025 om 16:35:23 UTC schreef [email protected]: Hi Hans, I did not make something like this but if you use the JAL library for the HC-SR04 you need to mutiplex the output of the device and connect the multiplexed signal to the interrupt pin of the PIC. Next to that you need also need to multiplex the trigger signal that goes to each HC-SR04 module.
