Hi,
My Robot is doing fine , after some little problems with the light sensors it is working ok. Making it look more away from each other and little bit downwards.
Now comes the question: I used an Atmega168-20 instead of the Atmega8. I modified the makefile, mcu and timerx8 etc like in the tutorial and given in this Forum.
As the robot is turned on, it runs like a circle to the left, circle is about 150cm wide. The left servo (looking from behind) is turning slower then the right one.
Somebody has this problem also ?
I measured the Light sensors and the resistor difference is about 100 ohms between the left and the right sensor in the same lighted situation. Can this make a speed difference ?
Must compensate this in the code ? If so what is the best option ?
