thanks a lot what I infer now is that for the same current I get more torque in full step than half step.

What is the difference between wave drive,full step and half step modes of stepper motor. Which of them is most efficient in terms of power consumption and efficiency? Which of them gives a smoother operation and how the coding changes with the mode

Can anyone pls help me on how to code the ADC of the atmega 32 microcontroller

Hi,
Can anyone please tell me why are all chips colored black? Is it something to do with power consumption or something like that?

How to build an analog circuit to control 5 LEDs with a single input (0V-5V)?
the input will vary from 0V to 5V and i need help designing an analog LED multiplexing circuit for 5 LEDs such that the output will be:
1V Light 1 on
2V Light 2 on
3V Light 3 on
4V Light 4 on
5V Light 5 on
PS:I know this…

OK thanks I ll try that and let you know

Thats what my calculation turned out to be but the batteries are draining in hardly 15 minutes after full recharge

Yes its total system power.
It is 1.8 amp-hour rating.
Just I would like to add one more thing. The current which I mentioned in previous case was when motors were running freely when the robot actually runs on ground the current is increasing to 1.0A-1.4A

Thanks,
I actually had done that but forgot to mention.
I measured the current when motors were spinning which was fluctuating between 120-150mA

In case the previous link is not posted properly pls see this one
