how do I know if it is the motor that is taking up a too much voltage when there is other stuff connected to the NXT too that will take up voltage

Hi, Can the NXT read the voltage before it goes to - terminal on the battery pack? This is to see if the motor load (on the axle) is too high, if it is then the current or voltage should increase (not sure if its current or voltage, probably current) if it does then I would need the program to someh...

how about using another method, I think the encoder method is going to take up too much space in my model, and it is not out for purchase yet.

also are pins 5 and 6 the yellow and blue ones since the NXT cable and connector goes with the latch facing up ontop?

I think ill be using this: or

I am not sure on what language to use yet, its just if the power goes up too much not if it goes slow, it has several speeds that can be set. if if pwm works best for what I need then ill probably use that but I still do not get if the pins on a NXT output port can input information or if an input p...

Hi, how can I use the NXT to measure the friction of a motor, this is useful if a gear geats jappned when swapping over or if the car hits a wall but tries to spin the wheels. with the output port it does not seem possible. and you cannot use input port with the motor. if a certain value is read (me...

Ok I should step back ,im sure somebody else will/has done this some method, after thinking, I dont think I know enough to even theoretically do something like that. But thanks again for helping out I am busy learning the basics of the PIC microcontroller architecture and workings but I am a little ...

No, use three output pins, latch, data and clock toget 8 or 16 inputs

The software that is arleady installed in the rom in the microcontrollers of the NXT brick can be changed so that the connectors for the motors and sensors can all be set to be 'input', i found this by reading the datasheets of the two microcontrollers in question, The ports are connected to registe...

Hi,

When I looked through the datasheets it seemed the processor can change it but although the processor can change it may be that the language or PCB will prevent it

It would be cool to have all the serial ports to be input.

Any ideas if it is possible and how?
