MAGracing Forum

Timing system is crucial for me - good racing is hard without. Make sure you have a strategy at place at once. Go with an existing one or easy adapted. We got it quite nicely with Race Coordinator as it has an open interface. (Sorry for the late post, I just haven't looked at this forum in ages) Ye...

Good work. Thanks

Would like more info on lap counter. Do you think it could be waterproofed, to avoid being damaged when installed in my outdoor track? The lap counter is the one described here: http://www.magracingforum.com/viewtopic.php?f=16&t=265 And yes, as others have mentioned it should definitely be poss...

For those interested in testing here's a simple C# application made with the free version of Visual Studio. It only supports car IDs 0-3, but should show how to work with the serial port and it should be easy to expand it to include more cars, a nicer look and so on. If you get a lot of "sensor...

colum 1 magracing car no from web colum 2 dip settings 0=low pos, 1=high pos. colum 3 car no readings in hex from the Arduino (human readable - enabled) Yes, the table is correct. What the Arduino sketch does is that it checks a number of pins (by default 0 to 7) and reports any car IDs spotted on ...

I have had a 'talk' with guys at http://www.racecoordinator.net. He was interested in incorporating MAGracing to their sw. That's good news :) If you need any help rewriting the Arduino code to e.g. output a different format for the car numbers please let me know. As far as I recall I had to make s...

That's great!
What software do you plan on using?

Your output (video) on the screen that would be the "Arduino serial Monitor ?" I actually think that's the program PuTTY, that can (among other things) dump the data received on a serial port. If there's a serial monitor with your other development tools then that should work equally well...

Sounds good. Please note that the photo does not show the IR photo transistors but only the "right half" of the schematic posted earlier in this thread. One simple test would be to disregard the Arduino at first and simply connect an LED where it says "To Arduino PINx". That LED ...

You specify : PNP transistor (BC547) That's because I'm a nitwit ;-) I did use BC547s but as you correctly say they're NPN. Sorry about that! If you're having problems it might be an idea to do a more simple test to check that the light sensors work and can activate the ports on the Arduino. Maybe ...
