Re: Hobby Components Maze Runner (HCROBO0052)

In fact the current download from your forum seems to be V0.1 (copy attached) The version stated at the beginning of each file is: Sorry I'm an idiot! I did downloaded the library but made the rookie mistake of forgetting to delete the existing library from the the library folder. I've now uploaded...

Re: Hobby Components Maze Runner (HCROBO0052)

If I might ask, since my sketch is running oddly on your robot as well as mine and you are looking for bugs in the library, does the demo Maze Solver sketch still work normally on your robot? In particular using the exact same example sketch and library that I am using, downloaded from the forum? Y...

Cheers for that. Please feel free to post a picture when it's finished I'd love to see it.

Re: Hobby Components Maze Runner (HCROBO0052)

I was just going to post you a test sketch to try this morning that ran the motors in a particular direction just before running the calibration routine but after seeing your post I gave your sketch a quick try and I'm seeing the same weird behaviour. What's even more weird is if I add some serial p...

Re: Hobby Components Maze Runner (HCROBO0052)

Ok, thanks. I'll take a another look at the code while you do that. Nothing jumped out at me when I looked at it before but I'll take another look with the fact that it is stepping though the calibration process at the correct rate in mind.

Re: Hobby Components Maze Runner (HCROBO0052)

I've been staring at the library and in particular the calibration routine but at the moment I can't see any condition that would cause it to not rotate the motors and yet still get to the end of the calibration routine. Can I check with you - does it immediately output the calibration results right...

Re: Hobby Components Maze Runner (HCROBO0052)

Regarding the test surface, my original "T" test maze was 20mm black tape on light cardboard which previously worked fine so it was fairly forgiving. I'm now using the same tape on white paper. I didn't know how important extraneous light is so it's been tried in daylight, artificial light and even...

Re: HCuOLED library for SSD1307 & SH1106 based OLED displays

Hi Chris, just to let you know I've tested the font and it looks great - so tiny! I've now updated the HCuLED library (V0.7) to include your fonts and I've also included the ability to use a different character spacing for each font with yours set to 1pt. Thanks again for this contribution.

Re: Hobby Components 4x4x4 64 LED cube kit (HCKITS0041 to 44)

Just given it a try and looks great. If you like I can include it into the library and credit you in the comments.

Re: Hobby Components Maze Runner (HCROBO0052)

Thanks for checking. The values from the test sketch all look sensible. I was hoping it would show a bad sensor as this would explain exactly what your seeing. The way that line sensing works is that IR light bounces off the surface and hits the appropriate IR receiver which is basically an IR opto-...
