yes, I had a look at the schematics.
In combination with the silk screen layout it would answer all questions concerning the hardware.
No hurry, I too have only enough time over the weekends.

Hannes - Topic: 4WD MiniQYou Reply: Hi all,
@Hector: Thank you for the modified code and especially for the additional "encoder test" program.
Well, now I realize what the real problem was.
You guys are using a Chinese environment, and my nose was too long to read the output well!
Ok, I took your new ROB0050EN and reworked every file with an european/(us) Arduino.
There were still errors in "Avoidance", "Key", "Light", "Remote" and "Song".
All files compile under 0023 (I don't have 0022 anymore) without errors now.
Please note: I only corrected the errors, I've done no download to the MiniQ yet.
Please see attached file ROB0050EN_hannes.rar

P.S.: Can I hope for a response to my questions remaining? - Topic: 4WD MiniQYou Reply: Hi all,

P.S.: Can I hope for a response to my questions remaining? - Topic: 4WD MiniQYou Reply: Hello,
I received my 4WD MiniQ from a local dealer today.
I love it at first sight.
But the first steps are not as easy as I thought.
Is is right that it comes with absolutely no documentation?
Well, I found the Wiki and I downloaded the examples.
Unfortunately the Wiki is very briefly.
Most of the examples come in two versions:
The first one has funny characters in the comments and is not very intructively.
The second one is rejected by the Arduino parser, because of numerous space characters at wrong places.
Correcting all the "# Define" to "#define", "> =" to ">=" and the "& &" to "&&" was annoying, but then it worked.
But even more I dfrobot a detailed layout description.
There are two pots.
Are they used for distance sensors sensivity?
What is the procedure to adjust?
There are some headers and jumpers.
One is for ISP. But the others?
The sensors confuse me.
Wiki says: Analog pin 0 is a line tracking sensor.
Is this the leftmost one or the rightmost?
Is pin 1 connected to the next one?
The infrared receiver seems to be the forefront part in the middle.
Is it used as distance sensor and remote receiver at the same time?
That would explain why the remote example works so poor.
What are the ambient light sensors for? Example?
How to use the wheel encoders? I did not found an example.
What are the IR codes of the remote control?
Only left, right, forward, back and stop are used in the remote example.
Sorry, if it sounds a litte disappointed.
I still think that this litte toy is great engineers work.
But the poor documentation belittings the practical value.
I would appreciate your help.
Thank you.
Hannes
