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]<mailto:[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.

Has anyone made something like this before? greetings Hans -- You received this message because you are subscribed to the Google Groups "jallib" group.
